Frequently asked questions

How does this differ from the magnetic version?

It is the same DS1990A-compatible key in the same fob, just without the iron retention ring — lower cost per unit, which is why large tenders and mass issuance default to it.

Does it work on magnetic readers too?

It reads on any standard TM reader, including magnetic ones — it just will not be magnetically held, so the user touches and holds it manually for the fraction of a second the read takes.

What customisation is available?

Stock housing colours for departmental coding, logo printing, and supply either loose or pre-assembled with the fobs — MOQ 100 pcs.
