Frequently asked questions
Is the TM card electrically the same as a TM key?
Yes — the same DS1990A-compatible 1-Wire chip, presented in an ISO card body (85.6 × 54 mm) so staff can carry it in a badge holder next to photo ID instead of on a key ring.
Can the cards be printed and numbered?
Yes — full-colour printing, sequential numbering and slot punching are all available, so the card doubles as a branded staff badge.
Does it work with existing TM readers?
Yes — touch the card’s contact to any Dallas-branch reader and it reads like a standard DS1990A key; no controller changes are needed.
