Key applications*Public transportation*Access control*Event ticketing*Gaming & identity MIFARE cards have three main differences from a standard proximity card:- The frequency of a MIFARE card is 13.56 Mhz. A standard 1386 proximity card is 125KHz.- The standard MIFARE card is factory programmed with a unique 32-bit serial number. This is a random number and does not contain a facility code. Most 26-bit proximity cards use a facility code within their configurations.- A MIFARE card has memory for storing values (typically up to 1 kilobyte of data). A proximity card does not have the capacity to store values.

RFID Readers & Prox Card Readers- It’s important to make sure your cards readers can “read” technology cards that are 13.56 KHz; your readers may only be able to read the 125KHz frequency. Also, MIFARE cards come pre-encoded with a unique 32-bit number, so you will need to make sure your software can read 32-bit formats.
