MIFARE DESFire EV2 contactless IC is the third generation of the MIFARE DESFire series product, which features fast and highly secure data transmission and flexible application management. It is functionally backward compatible with both MIFARE DESFire EV1 and MIFARE DESFire D40 (MF3ICD40) and it can hold as many different applications as the memory size supports.
Compared to MIFARE DESFire EV1 a MIFARE DESFire EV2 chip can hold as many different applications as the memory size supports and new applications can be loaded after the card has been deployed into the market. A purse can even be shared between applications, for greater interoperability.
