Existing customers who may have multiple Tenants using multiple card formats and Facility Codes run into the the problem where there are duplicate cards that may have been ordered or handled differently. In Access Expert, when the card is added an error shows up indicating that the card is already assigned and cannot be added to another person. Card offsets can be introduced in order to ensure no overlapping card number values.
In order to resolve this issue, the following steps need to be followed:
1. Create a new Card Format using the same Tenant Information
2. Add a card number offset, which is added to the original value. ie. a Card Offset of 1000 would make card 100 read as 10100.
3. Save and Close
4. Reboot the controller
