The TDSi 2920-3003 Mifare 4K cards are the kind of access control credential you buy when you need things to work reliably across a range of door readers and systems. Operating at 13.56 MHz, each card carries 4K bytes of memory — enough headroom for multi-application deployments where a basic 1K card simply won't do. Each card comes printed with a unique serial number, which makes issuing, logging, and managing credentials considerably less painful than it might otherwise be.

Supplied in packs of 100 and cut to the standard CR80 format (86mm × 54mm), these cards slot straight into any ID card printer or laminator you're already using. A practical choice for facilities managers, security installers, or anyone running a TDSi access control system who needs a dependable, compatible card stock to keep operations moving.
