About this card
The HID iCLASS Key II 2054 is the high-memory keyfob version of the iCLASS credential: a 13.56 MHz contactless smart chip with 32k bits (4K bytes), partitioned 16k/16 plus 16k/1, moulded into a small black fob with a blue HID insert. It goes on a key ring or a badge clip and reads on the same iCLASS and iCLASS SE readers as the cards.
A fob suits people who never wear a badge — maintenance, drivers, contractors, after-hours staff — and sites that want a credential which survives being carried in a pocket. It is moulded rather than printed, so there is no photo ID, no artwork and no magnetic stripe. If you need the credential to double as a visible ID badge, use the iCLASS 2004 card instead. Choose the 32k fob when the credential has to carry more than door access; for access control alone the iCLASS Key II 2050 does the same job for less.
To order programmed fobs, give us three things: your card format, your facility or site code, and the starting number. They are printed on the box your current credentials came in, or on your original HID paperwork. We encode every fob in the run in sequence from your start number. Printed numbering, where you choose it, is laser-engraved on the back of the fob.
