How do I enrol it?
On the device’s user page click Obtain and hold the card on the reader, or capture it at a desk with the Akuvox ACR-CID01 USB reader.
Can the card be encrypted?

Will it work on 125 kHz readers?
No. It is a 13.56 MHz card. 125 kHz-only readers will not read it.
Should I choose DESFire EV3 instead?
