Hi Onyekachi,

Please take in mind: the DESFire EV1 is a security product, but the MIFARE Ultralight it is not! Of course, there are the possibility to protect pages on the Ultralight with a key, but you cannot compare this feature with the key management on a DESFire EV1.

The OTP counter allows for instance a ticket application the usage of a limit time. Each time the ticket is used, the OPT set one bit to 1. After an amount of usages the ticket cannot be used anymore because the bits cannot be reset to 0. Please note, the Ultralight is used very often in “paper tickets”.
