The HID 1431 FlexSmart cards are the kind of solution that makes access control genuinely straightforward — combining HID proximity and Mifare smart card technologies in a single CR80 card (86mm x 54mm). They support all standard HID proximity card formats, with mutual authentication, data encryption, and a unique 32-bit serial number built in. Compatible with most ID card printers, these are cards that fit into existing infrastructure without demanding changes to it.

Sold in packs of 100, they suit organisations running dual-technology environments or looking to future-proof their access systems without replacing readers site-wide. The contactless format keeps things practical at the door — no swiping, no contact wear, no fuss.

These are a customised product with an estimated lead time of 5–30 working days. Once your order is confirmed, the team will be in touch to agree the format, facility code, and number range required — so the cards arrive ready to deploy.
