MIFARE smart cards are a brand of ISO 14443 Type A 13.56 MHz contactless smart card encoding technology, using read/write functionality to securely share information. MIFARE smart cards can also use 125 kHz prox card technology, allowing your cards to be multi functional, such as Touch N Go access card.
This technology is available in several styles, each with different abilities. This allows you to select the card style that meets your card program’s needs. MIFARE cards, fobs, and tags can store more data than a prox card, with options for 1k Byte (8k bits) or 4k Bytes (32k bits) on many of their cards.
