MIFARE CONTACTLESS CARD TECHNOLOLGY AN HID WHITE PAPER GENERAL The MIFARE contactless smart card and MIFARE card reader/writer were developed to handle payment transactions for public transportation systems. Although contact smart cards could also do the job, contactless readers are faster and easier to use, and there is virtually no maintenance on the readers, or wear and tear on the cards. MIFARE technology is owned by Philips Electronics. They do not make cards or readers, but they make and sell the card and reader chips on the open market. A reader chip is not required to read the card’s fixed random ID number, but it IS required to access any data stored on the card. Philips has also licensed manufacture of the card chip technology to Infineon. Similarities between MIFARE and Proximity : Both are passive cards (no battery) Both consists of a chip and a coil antenna Both are available in ISO card packages, fobs, discs Both use RF energy to power the chip and send and receive data Differences between MIFARE and HID Proximity : MIFARE PROXIMITY 1 - 4 inch read range 3 - 30 inch range Uses a frequency of 13.56 MHz Uses 125 kHz 1000 bytes of data storage 85 bits of data storage Holds 16 separate applications Holds one application Open standard Proprietary standard HOW MIFARE IS USED In fare collection systems, a MIFARE transit card is issued to a passenger, who goes to an automated terminal and uses a credit card or cash to load value on to the card. The value is stored in an “electronic purse” on the card, from which the appropriate fare is subtracted every time the passenger boards a bus or train. When the stored value is used up, the passenger goes to the automated terminal and reloads the electronic purse. Philips recommends the MIFARE cards for automatic fare collection, toll roads, airline ticketing, loyalty schemes, park and ride, prepaid metering, and phone, banking, city, ID and university cards. Although MIFARE cards have security features, such as encrypted RF transmission, mutual authentication, and security keys, most banks do not feel that MIFARE has

The MIFARE card has up to 16 separate sectors, which can be configured as purses or for general data storage. The first sector is typically used as a directory for the rest of the card, leaving 15 segments available for data or purses. Up to 15 different applications can be stored on a MIFARE card, and these applications
