T5577 Keyfobs & Epoxy Tags · UID-Changeable Tags
The contactless consumables: rewritable 125 kHz T5577 and UID-changeable 13.56 MHz tags.
For sites moving from contact keys to RFID: T5577 keyfobs and epoxy drop tags that a duplicator can program to EM4100-class IDs, and UID-changeable 13.56 MHz epoxy tags for systems that verify sector 0. Intended for mixed estates — old Dallas doors and new RFID panels alike; whether they can be combined with TM blanks in one order is confirmed in the quote. Compatibility depends on your reader, controller and firmware; test a sample on your own system before ordering.

Typical applications
Frequently asked questions
Which systems do the T5577 fobs work with?
They are intended for 125 kHz panels that read EM4100-class IDs: a duplicator programs the required ID onto the T5577. Whether a given panel accepts the result depends on the panel, its firmware and the duplicator; test a sample before ordering.
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 is intended to take the source card’s UID so that it can be recognised. Acceptance depends on the system and its firmware; test a sample first.
Can RFID fobs be ordered together with TM blanks?
Ask us to quote them together — a combined order can suit a mixed estate of old Dallas doors and new RFID panels; combined orders and shipping are confirmed in the quote. Fob or epoxy mini-tag formats, colour, marking and other customization options: feasibility, MOQ and cost are confirmed in the quote.
