TARJETA BLANCA MIFARE\u00ae 4K QUALICA-RD HQ\u00a0
\n1. \u00bfQu\u00e9 es MIFARE\u00ae?<\/p>\n
La tecnolog\u00eda MIFARE\u00ae es una tecnolog\u00eda RFID a 13,56 MHz ISO 14443A y 14443B fabricada por Philips.<\/p>\n
A menudo se hace referencia a MIFARE\u00ae como una tecnolog\u00eda de \u201ctarjeta inteligente\u201d. Esto se basa en el hecho de que la tecnolog\u00eda MIFARE\u00ae permite leer y escribir en la tarjeta. En realidad, MIFARE\u00ae es simplemente una tarjeta de memoria en sus versiones Classic, Icode, ultralight y si es criptogr\u00e1fica (inteligente) en las versiones con procesador Desfire, Plus, Ultralight C.<\/p>\n
Las tarjetas inteligentes sin contacto MIFARE\u00ae y los lectores\/escritores de tarjetas MIFARE\u00ae fueron desarrollados inicialmente para transacciones de pago en sistemas de transporte p\u00fablico. Gracias a su corto alcance de lectura, la tecnolog\u00eda MIFARE\u00ae resultaba especialmente apropiada para realizar funciones de adici\u00f3n\/sustracci\u00f3n. Aunque las tarjetas inteligentes de contacto tambi\u00e9n pueden hacer esas funciones, los lectores sin contacto son m\u00e1s r\u00e1pidos y f\u00e1ciles de usar y pr\u00e1cticamente no necesitan mantenimiento. Las tarjetas sin contacto, por su parte, casi no sufren desgaste.<\/p>\n
2. Cu\u00e1l es el alcance de lectura t\u00edpico de los lectores de tarjetas sin contacto MIFARE\u00ae?<\/p>\n
El alcance t\u00edpico de lectura de un lector de tarjetas inteligentes sin contacto MIFARE\u00ae es de 2,5 a 10 cm en sus versiones Classic, Desfire, Ultralight, Icode y de hasta varios metros en la versi\u00f3n Icode (con lector especial). En Norteam\u00e9rica, debido a las regulaciones de la FCC, el alcance de lectura est\u00e1 en la parte inferior de la escala.<\/p>\n
3. \u00bfLos lectores de tarjetas sin contacto MIFARE \u00aese pueden utilizar en sistemas existentes de control de acceso?<\/p>\n
Los lectores MIFARE\u00ae de tarjetas inteligentes sin contacto pueden utilizarse junto con sistemas existentes de control de acceso. Hay algunos aspectos t\u00e9cnicos que se debe tener en cuenta:<\/p>\n
La tarjeta est\u00e1ndar MIFARE\u00ae viene programada de la f\u00e1brica por Philips con un n\u00famero de serie \u00fanico de 32 bits. Este es un n\u00famero aleatorio que no contiene un c\u00f3digo de lugar. Si usted est\u00e1 utilizando otro formato de bit en su sistema de control de acceso y desea utilizar simult\u00e1neamente tarjetas\/lectores sin contacto MIFARE\u00ae de 32 bits, aseg\u00farese de verificar que el sistema de control de acceso en uso acepte simult\u00e1neamente m\u00faltiples formatos de bit y c\u00f3digos de lugar.<\/p>\n
4. \u00bfQu\u00e9 capacidad de memoria tienen las tarjetas MIFARE\u00ae?<\/p>\n
Depende de la MIFARE\u00ae de que se trate. El m\u00f3dulo MIFARE\u00ae S50, de Philips, con un (1) Kbytes de memoria EPROM. MIFARE\u00aeS70 4Kbytes de memoria EPROM. Desfire, 2, 4, 8Kbytes, etc.<\/p>\n
5. \u00bfCu\u00e1ntos sectores tienen las tarjetas MIFARE\u00ae?<\/p>\n
La tarjeta MIFARE\u00ae 1K (la m\u00e1s com\u00fan de todas) tiene 16 sectores independientes que pueden configurarse como \u201cmonederos\u201d o para almacenamiento de informaci\u00f3n general. El primer\u00a0sector (0) se usa com\u00fanmente como directorio de la tarjeta y contiene el UID (bloque 0), con lo que quedan otros 15 segmentos para datos o \u201cmonederos\u201d. Los bloques 3 contienen las llaves de seguridad Key A y Key B por lo que tampoco son h\u00e1biles para almacenar datos.<\/p>\n
6. \u00bfCu\u00e1ntas aplicaciones pueden alojarse en una sola tarjeta MIFARE\u00ae?<\/p>\n
En total, en una tarjeta MIFARE\u00ae se puede almacenar un m\u00e1ximo de 15 aplicaciones diferentes. Estas aplicaciones se separan individualmente utilizando claves \u00fanicas (contrase\u00f1as) paracada sector. El \u00fanico requisito es que los distintos suministradores de aplicaciones deben cooperar en la programaci\u00f3n del Directorio de Aplicaciones MIFARE\u00ae (MAD, por sus siglas en ingl\u00e9s) y que las claves de estos directorios deben estar a disposici\u00f3n de todos los suministradores de aplicaciones.<\/p>\n
7. \u00bfCon qu\u00e9 est\u00e1ndar ISO cumplen las tarjetas MIFARE\u00ae?<\/p>\n
MIFARE\u00ae es una tecnolog\u00eda de no contacto a 13,56 MHz, descrita en el est\u00e1ndar ISO 14443 Tipo A (Classic) y B (Desfire). Esta tarjeta est\u00e1 dise\u00f1ada para permitirle incrustar un m\u00f3dulo opcional de chip inteligente de contacto. En caso de hacerlo, la tarjeta tambi\u00e9n cumplir\u00eda con el est\u00e1ndar ISO 7816. Esta tarjeta est\u00e1 dise\u00f1ada para tener una banda magn\u00e9tica. En la configuraci\u00f3n con banda magn\u00e9tica, la tarjeta tambi\u00e9n cumple con el est\u00e1ndar ISO 7811.<\/p>\n
8. \u00bfLa informaci\u00f3n MIFARE\u00ae se encripta?<\/p>\n
La transmisi\u00f3n de datos por radiofrecuencia entre la tarjeta y el lector MIFARE\u00ae se encriptan. Sin embargo, los datos que almacenamos en la tarjeta no se encriptan. El acceso a los datos est\u00e1 protegido por una clave de 48 bits, por lo que solo pueden ser le\u00eddos por un lector que contenga la clave correcta.<\/p>\n
La tecnolog\u00eda MIFARE\u00ae permite la autenticaci\u00f3n mutua entre la tarjeta y el lector. Se genera un n\u00famero aleatorio y, de acuerdo con las claves, se env\u00eda un mensaje desde la tarjeta hasta el lector. El lector entonces le env\u00eda un mensaje a la tarjeta. Esta operaci\u00f3n se realiza tres veces para verificar que la tarjeta que se ha presentado ante el lector es v\u00e1lida.<\/p>\n","protected":false},"featured_media":46168,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false},"categoria-productos":[606,612,617],"class_list":["post-46167","productos","type-productos","status-publish","has-post-thumbnail","hentry","categoria-productos-cards","categoria-productos-biodegradable-plastic-cards","categoria-productos-mifare-13-56-mhz"],"acf":{"ACF_PRODUCTO_texto_descripcion":"
