13.56MHz RFID keys and cards support both ISO 14443B or ISO 15693 protocols
With a 13.56MHz interface, these secure keys come packaged in a laminated plastic key fob or ISO thin card format and are available in either the ISO 14443B or ISO 15693 HF protocol. Each protocol family offers three products: 64-bit ROM ID only (MAX66000/MAX66100), ROM ID plus 1K-bit EEPROM (MAX66020/MAX66120), or ROM ID plus 1K-bit EEPROM and SHA-1 authentication (MAX66040/MAX66140). Custom form factors are also available. The MAX66040 and MAX66140 employ the secure hash algorithm (SHA-1), an ISO standard that is publicly available and has been thoroughly tested in the marketplace. It is designed to maintain the integrity of the stored data so that one can verify the authenticity of any credential. Maxim’s RF keys and cards are custom programmable to match the requirements of new and existing tag populations. They work with most 13.56MHz readers on the market, thus providing an alternative tag source for existing systems.
