It generally allows for normal dual-sided use. However, due to differences in RFID technology, signal strength, and reader compatibility across different cards and terminals, we cannot guarantee functionality for all card combinations. This product is primarily a custom leather good, and as such, it is final sale with no returns or exchanges. The dual-sided RFID functionality is an added feature and not a guaranteed performance, nor will it be accepted as a reason for return.
