Q&A: RFID Cards for iFace Timeclock & Door Access

Q: Are there specifications available for an RFID card compatible with both the iFace timeclock and door access system?
A: Not at this time. Our vendor was unable to provide compatibility specifications. If additional details become available, we will share updates accordingly.


Q: Can we print employee photos, names, and company info on RFID cards if we purchase our own card printer?

A: Yes, clients may use their own card printer to print images or text onto the cards. A sample RFID card can be provided upon request, or one should already be included in the box with each iFace timeclock.
