My ring (NTAG216) works perfectly with the Dorma Kaba evolo cylinder when using a Mifare master card. I assume it won't work when you use a Legic master card however I have not tested this.

Here in Switzerland most offices use a legic badge for opening doors. However, most other applications like public transport use Mifare Desfire.

My wish is as NFC ring with the new ATC4096-MP312 chip that combines those two worlds.

Dormakaba evolo locks work well at least when using a Mifare master card and whitelist mode.

+1 and use Mifare Desfire Ev2 so one can use it with different mastercards
