T5577 is a popular 125kHz option due to its read/write capabilities.
Unlike other read only proximity cards, such as EM4102, these T5577 re programmable, offering the ability and opportunity to program your own numbering to suit your system requirements, duplicate, or imitate existing cards and more with a range of 125kHz compatible readers.
These cards are supplied blank/unprinted. If you would like these cards printed, or programmed, please do let us know and we will provide a bespoke quotation to meet your requirements.
T5577 is also available as a key fob, offering all the same functionality in a different form factor.
