Mifare cards are designed for convenient, fast transactions. The cardholder does not need to stop at the card reader for the card to be read. This high-speed processing allows for high throughput at gates, boarding areas, and toll booths. Mifare cards can even remain in a wallet or purse during the transaction.
Mifare cards are compatible with existing Mifare infrastructures. The cards are available in 100% PVC or composite PVC-PET, 1 or 4 kByte EEPROM read/write memory, and with or without a magnetic stripe.
