The TDSi 2920-3000 Mifare 1K cards are proximity cards designed to work within TDSi access control systems — the kind of straightforward replenishment purchase that should be exactly what it says on the box. Each card carries 1K byte of memory and operates at 13.56 MHz, the standard frequency for Mifare-compatible readers.
Cards are supplied in packs of 100 at CR80 size (86mm x 54mm) — the same dimensions as a standard credit card, which means they sit neatly in wallets, cardholders, and lanyards without any fuss. If your site is already running TDSi infrastructure, these are the cards to match it.
