T5577 Keyfobs & Epoxy Tags · UID-Changeable Tags
The contactless consumables: rewritable 125 kHz T5577 and UID-changeable 13.56 MHz tags.
As intercom estates migrate from contact keys to RFID, the same counters that buy RW1990 start asking for these: T5577 keyfobs and epoxy drop tags that a duplicator programs to EM4100-class IDs, and UID-changeable 13.56 MHz epoxy tags for systems that verify sector 0. Stocked alongside our TM line so one shipment covers a mixed estate — old Dallas doors and new RFID panels alike.

Frequently asked questions
Which systems do the T5577 fobs work with?
Any 125 kHz panel that reads EM4100-class IDs — the duplicator programs the required ID onto the T5577, which is why it is the standard consumable at key-copying counters for RFID doors.
What is the UID-changeable 13.56 MHz tag for?
For 13.56 MHz systems that verify the card UID (sector 0): an ordinary tag with a fixed UID cannot be enrolled as a copy, while the UID-changeable version takes the source card’s UID and is accepted.
Can RFID fobs be ordered together with TM blanks?
Yes — mixed cartons with RW1990 and other TM blanks are routine, so one shipment covers a mixed estate of old Dallas doors and new RFID panels. Fob or epoxy mini-tag formats, colours and logo printing to order.
