The conceptual difference in one sentence

RFID is the family: it covers all forms of radio identification. NFC is a specific type of RFID: it operates at 13.56 MHz over a very short range (less than 10 cm) and supports secure two-way communication. This is why it underpins contactless payments and many modern access cards.

The 5 technical differences that matter

1. Frequency and reading range

NFC: 13.56 MHz · maximum range of approximately 10 cm · designed for very short-range interaction.

RFID HF (Mifare, NFC): 13.56 MHz · range from 1 cm to 1 m, depending on the antenna.

RFID LF (125 kHz – EM, Temic, HID Prox): up to 1 m, simple readers and widely used in legacy systems.

RFID UHF (860–960 MHz): range from 3 to 15 m, depending on the antenna; used for inventory and traceability.

2. Security and encryption

NFC and RFID HF support robust encryption (AES, 3DES, Mifare DESFire EV2), enabling cards that are extremely difficult to clone. Basic RFID LF technology (HID Prox 125 kHz) is vulnerable to cloning with inexpensive devices, which is why new projects are moving towards HF/UHF.

3. Memory and data capacity

NFC cards can store several kilobytes of structured data, such as credentials, encrypted biometric data and an electronic wallet. LF cards store only an ID. This difference makes it possible to use NFC for access, payments and transport on a single card.

4. Mobile device use

Only NFC allows a mobile phone to be used as a credential through services such as Apple Wallet, Google Wallet and digital car or building keys. RFID UHF and LF cannot be accessed from a standard smartphone.

5. Cost and ecosystem

LF cards are cheaper and remain suitable for legacy systems. NFC cards cost slightly more but offer stronger security, multiple functions and a longer service life. UHF tags are inexpensive (€0.10–€0.30) and are used for pallets, assets and clothing.

Summary table: NFC vs RFID

When should each technology be used for access control?

NFC / RFID HF (13.56 MHz) is the default choice for new projects because it offers cryptographic security, electronic-wallet capabilities, mobile compatibility and manageable obsolescence. We recommend Mifare DESFire EV2 as the de facto standard for businesses.

RFID LF (125 kHz) should be retained only in legacy systems where thousands of cards have already been issued. Migrating to 13.56 MHz often recovers its cost in less than 18 months by reducing incidents.

RFID UHF does not compete with NFC for personal access control. It is designed to read tags at a distance, such as pallets, assets and clothing in shops. It is often combined with NFC in advanced logistics projects.

Frequently asked questions about NFC and RFID

Are NFC and RFID the same?

No. NFC is a specific technology within the RFID family. RFID covers all forms of radio identification, including LF, HF, UHF and microwave. NFC always operates at 13.56 MHz and over a very short range.

Can I use my phone as an access card?

Yes, but only with NFC technology. Most current smartphones support NFC and can store digital access credentials in Apple Wallet or Google Wallet. You need an up-to-date NFC reader and a system that can issue mobile credentials.

Are 125 kHz RFID cards secure?

Basic versions such as HID Prox and EM4100 are vulnerable to cloning. Encrypted versions such as HID iClass are available, but they cost more. The current industry recommendation is to migrate to Mifare DESFire EV2 (13.56 MHz) for any new project.

Which RFID card should I buy for my company?

If you are starting from scratch, choose Mifare DESFire EV2 (13.56 MHz) in PVC or biodegradable material. If you already have an LF system and many users, consider a gradual migration with dual-technology readers that accept both types of card during the transition.

How can I test NFC and RFID before buying?

Qualica-RD can send you a sample kit with several card models (Mifare, Temic and UHF) and compatible readers. Request one with no obligation and we will help you validate the technology before deployment.

What is an industrial ruggedized terminal (and what it is not)

A ruggedized terminal is a handheld or tablet-type device, with Android operating system, that integrates in a single device: 1D/2D barcode scanner, interchangeable battery, 4G/5G/Wi-Fi/Bluetooth connectivity and, depending on the model, UHF RFID, NFC, fingerprint reader or industrial camera.

It is not:

• An “outdoor” mobile with a case. The real IP certification requires factory sealing.
• An old PDA with Windows CE. We are talking about Android 10/12/14 with an open SDK.
• A pure scanner. The advantage of the terminal is to unify capture + computing + connectivity in a single device.

The 7 criteria that we apply to recommend a model

Not all terminals are suitable for everything. These are the seven criteria we use with our clients:

1. Type of code to read

Does your operation read only 1D codes (EAN, Code 128) or also 2D (QR, Data Matrix, PDF417)? Most current models read both, but it is advisable to confirm it. For reading damaged codes or those printed on a mobile screen, the 2D imager module is mandatory.

2. Distance and reading conditions

On shelves at 1.5 m, a standard imager is sufficient. If you work with pallets at 6-8 m, you need long-range UHF RFID. If you combine both, look for dual models like the Qualica-RD range RD 50, RD 60, RD 72 or RD R6.

3. Physical environment: IP, drops, temperature

IP certification is the most misleading piece of data. IP65 = protected against dust and water jets (suitable for warehouse). IP67 = brief immersion (construction site, outdoors, cold storage room with condensation). Also ask for drop rating: 1.2 m, 1.5 m or 1.8 m onto concrete. And operating temperature range: a terminal working in a cold storage at -10 °C is not the same as one in a warehouse at 25 °C.

4. Autonomy and battery management

What defines a bottleneck-free operation is the battery. Models with hot-swap battery (replaceable without powering off) such as RD 60, RD 70, RD 71, RD 72, and RD 75 cover shifts of 10-14 hours without interruptions. Tablets (RD 80, RD 100) typically last 8-10 hours with fast charging.

5. Operating system and SDK

Android 10/12/14 with open SDK and FOTA update support for 3-5 years. This prevents the device from becoming obsolete due to Google updates and allows you to integrate it with your ERP or WMS with total freedom.

6. Real connectivity (not just “Wi-Fi”)

Wi-Fi must support fast roaming between APs (802.11r/k/v) if the site is large. 4G/5G for mobile fleets. Bluetooth 5.0+ for accessories (printers, readers). USB-C with OTG for charging and data.

7. Ergonomics and intensive use

Weight, grip with glove, scan trigger, sunlight-readable screen, fog resistance. Ergonomics is invisible in the technical data sheet but accounts for 80% of returns.

Comparison of the Qualica-RD range for industrial use

What to look for (and what to ignore) on the datasheet

What matters: real IP rating (not “splash-resistant”), drop height in meters onto concrete, battery life under intensive use (not in stand-by), open SDK, FOTA, warranty and spare parts stock in your country.

What is overrated: the number of processor cores, the exact version of Gorilla Glass and the megapixels of the rear camera. A professional terminal does not need more than 13 MP on the camera; what it needs is reliability for 3 years.

How to avoid the 5 most common mistakes

1. Buying by catalog instead of by use case. A terminal for cold logistics is not the same as for mobile retail.
2. Ignore integration with ERP/WMS. Closed SDK = eternal dependence on the manufacturer for any changes.
3. Do not budget for additional hot-swap batteries. Without a second battery, a 12-hour operation stops.
4. Choosing IP65 when IP67 is needed. Water jets and momentary immersion are not the same.
5. Failure to validate ergonomics with gloves. Screen that does not respond to work gloves = returns per month.

Frequently asked questions about industrial ruggedized terminals

What is the difference between IP65 and IP67 in an industrial terminal?

IP65 protects against total dust and water jets (valid for standard warehouse). IP67 adds resistance to brief immersion (1 m for 30 min), therefore it is mandatory on construction sites, outdoors with heavy rain and cold rooms with condensation.

How long does the battery last on average under intensive use?

Between 10 and 14 hours of continuous use in models with hot-swap (RD 60, RD 70, RD 71, RD 72, RD 75). Tablets (RD 80, RD 100) last around 8-10 hours. We always recommend two batteries per device to cover long shifts without interruption.

Do they work with my ERP or management software?

Yes. The Qualica-RD range works on Android with an open SDK and supports HID (keyboard mode), OPOS, COM emulation and native APIs. It is compatible with SAP, Oracle WMS, Manhattan, Bluetensor, Compact and any custom development via REST API.

Do I need technical support in Spain?

It is essential. Qualica-RD offers direct support, official warranty, and spare parts stock from Spain, with repair SLA and equipment loan. Avoid models whose warranty depends on shipments from Asia.

And data security?

Qualica-RD terminals support Android Enterprise, disk encryption, remote MDM (wipe/lock in case of theft) and, in models with SAM modules (RD 71), can store secure credentials for digital signature or corporate identities.

You have to implement an access control or time and attendance system in your company. You know you want biometrics because it is more secure than RFID cards (which can be lost, lent or cloned) and more convenient than PIN codes (which can be forgotten or shared). But when you open the catalog you come across fingerprint, facial recognition, palm recognition, iris… and you don’t know which one fits your actual operational needs.

This article helps you decide with objective criteria: cost, speed, hygiene, work environment, precision, and user acceptance. No smoke. No manufacturer bias.

The 4 biometric technologies competing in access control

1. Fingerprint: the reliable veteran

How it works: The sensor captures the characteristic points of the fingerprint (minutiae) and generates a mathematical template. It does not store the fingerprint image.

Accuracy: False Acceptance Rate (FAR) less than 0.001%. False Rejection Rate (FRR) less than 1% under normal conditions.

Speed: 0.5-1 second per reading. It is the fastest.

Cost: It is the most economical technology. Fingerprint readers cost between 30% and 50% less than equivalent facial recognition readers.

Ideal for:

Known issues:

Usage advice: If 95% of your employees have no skin wear issues, fingerprint is the most cost-effective option. For the remaining 5%, offer RFID card as an alternative.

2. Facial recognition: the post-pandemic star

How it works: An infrared camera captures the nodal points of the face (distance between eyes, nose width, jaw contour). It works with a mask on the most recent models.

Precision: FAR lower than 0.0001% in the best models. The technology has improved dramatically with the advent of deep learning algorithms.

Speed: 1-2 seconds per read. Slower than fingerprint but acceptable for most applications.

Cost: It is the most expensive of the three main options. A facial recognition terminal costs between 40% and 60% more than one with fingerprint only.

Ideal for:

Known issues:

Usage tip: If your priority is hygiene and contactless, facial recognition is the answer. But be prepared for a more rigorous DPIA and more careful internal communication with employees.

3. Palm reading: the great unknown (and possibly the best for many cases)

How it works: A sensor captures the vein pattern of the palm of the hand using near-infrared light. The vein pattern is unique, internal (not externally visible) and does not change with age.

Precision: FAR lower than 0.00008%. It is the most accurate of the three because the vein pattern has more identification points than the fingerprint and is not affected by cuts, dirt, or wear.

Speed: 1-1.5 seconds. Similar to facial recognition.

Cost: Intermediate between fingerprint and facial. Less demand means fewer economies of scale, but the difference with facial is narrowing.

Ideal for:

Known issues:

Usage tip: If you work in heavy industry, construction, or very dirty environments where fingerprint constantly fails, palm is your technology. Less known, but more reliable where others fail.

4. Iris recognition: the maximum security option

How it works: A high-resolution camera captures the unique pattern of the eye’s iris. It is the most accurate biometric method that exists.

Precision: Virtually infallible. FAR less than 0.00001%.

Speed: 2-3 seconds. The slowest.

Cost: The most expensive of all. It is only justified in maximum security environments.

Ideal for:

Not recommended for: Standard employee time tracking. The cost and user friction are not worthwhile compared to fingerprint or palm.

Quick comparison: decision table

The factor that nobody tells you: user acceptance

You can choose the most advanced technology on the market, but if your employees don’t accept it, the project fails. This is what we have learned in hundreds of implementations:

Practical recommendation: Before deciding, talk to the workers’ representatives. Explain the alternatives to them. And always offer a non-biometric option (RFID card or PIN) as a voluntary alternative. The GDPR requires it, but it is also the best strategy to avoid labor conflicts.

What if I combine several technologies in the same terminal?

This is the smartest trend for 2026. The ruggedized multifunction terminals like those in our QualicaRD range integrate fingerprint + facial + RFID + NFC + barcode in a single Android device. This allows you to:

It is the option we recommend in 80% of projects because it eliminates the risk of choosing the wrong technology and gives you flexibility to adapt on the fly.

Conclusion: there is no “best” biometrics

There is the best biometrics for your specific case. And that depends on your sector, your physical environment, the profile of your employees, and your level of demand in terms of privacy.

If after reading this you still have doubts, contact our technical team. We help you choose without obligation and without bias. Because our goal is not to sell you the most expensive terminal, but the one you really need.

La entrada Fingerprint vs Facial Recognition vs Palm: Which Biometric to Choose for Your Access Control? se publicó primero en Qualica-RD.

This is the question we receive most at QualicaRD. The short answer is yes, it is legal, but with very specific conditions that you must know before installing any biometric system in your company.

The General Data Protection Regulation (GDPR) classifies biometric data as special category data (Article 9), which means it enjoys the highest level of protection. You cannot treat it as if it were a simple RFID card number. You need a legal basis, an impact assessment, and specific technical measures.

In this guide we explain exactly what Spanish and European regulations require, what the AEPD has said in its latest resolutions, and how to implement a biometric access control that complies with the law without sacrificing operational efficiency.

What exactly does the GDPR say about biometric data?

Article 9.1 of the GDPR prohibits the processing of biometric data aimed at uniquely identifying a natural person. The prohibition is the general rule.

However, Article 9.2 establishes exceptions. The most relevant for access control and labor time recording is letter b): the processing is necessary to fulfill obligations in the field of labor law.

This means that:

The AEPD resolutions you should know

The Spanish Data Protection Agency has been especially active in this area. These are the key resolutions:

Resolution on biometric time recording at work (2023-2024): The AEPD has validated the use of fingerprint for time control provided that:

Criterion on facial recognition: The AEPD is more restrictive with facial recognition than with fingerprints. It considers it a high-risk technology and requires a higher level of justification. In work environments, it is only allowed for access to critical security areas (defense, essential infrastructures, sensitive data).

Compliance checklist: 7 steps to implement biometrics without problems

1. Define the legal basis BEFORE buying the system

Do not buy biometric terminals and then look for legal justification. Do it the other way around. First determine whether your use case fits into one of the exceptions of Article 9.2 of the GDPR.

2. Carry out an Impact Assessment (DPIA)

It is mandatory for any large-scale processing of biometric data. It must include:

The AEPD offers a free template on its website. Don’t skip it.

3. Choose terminals that encrypt biometric templates

Here is the technical difference that really matters. A biometric terminal must never store images of fingerprints or faces. It should only store biometric templates: irreversible mathematical representations of the characteristic points of a fingerprint or a face.

QualicaRD ruggedized terminals, for example, generate an encrypted hash of the fingerprint at the moment of capture. The original image is immediately discarded. The template cannot be used to reconstruct the original fingerprint. This is exactly the architecture that the AEPD expects to see in an EIPD.

4. Always offer an alternative to the worker

Although clocking in is mandatory, the biometric method cannot be mandatory. Offer each employee the option to use a personal RFID card or a PIN code. Document that you have offered this alternative.

5. Report transparently

Each employee must receive and sign an information clause detailing:

6. Minimize data: do not ask for more than necessary

If you only need time recording, don’t also capture the face. If you only need access to a door, don’t link the biometric data to the employee’s complete file. Principle of minimization: the GDPR punishes disproportionality.

7. Set retention and deletion deadlines

Biometric data cannot be kept indefinitely. Define a clear period (e.g., 5 years from the employee’s termination, unless there is a legal obligation to retain it for longer) and automate the deletion once that period is fulfilled.

Cloud biometrics vs local biometrics: the decision that defines your risk level

This is the point where many companies mess up without knowing it.

Cloud systems: Biometric data is stored on external servers. Higher risk of security breach. More difficult to justify to the AEPD. Only recommended if your DPD expressly supports it.

Local systems (on-premise): Biometric templates are stored exclusively in the terminal’s memory, without internet connection. This architecture best aligns with the GDPR minimization principle and is the one that the AEPD views most favorably.

Our ruggedized terminals allow both configurations. But if you ask us which one we recommend from a regulatory compliance point of view: always local, with the possibility of occasional export of clocking records (never templates) to your ERP.

Penalties: what non-compliance can cost you

GDPR sanctions for inadequate processing of biometric data can reach 20 million euros or 4% of global annual turnover, whichever is greater.

In Spain, the AEPD has imposed fines from €2,000 (minor cases, such as not having an information clause) to over €200,000 (serious cases, such as capturing a fingerprint without an alternative or DPIA). The cost of doing it right is ridiculous compared to the cost of doing it wrong.

Practical summary: what do you need to be in compliance?
