Radio Key® Proximity credentials are smart, reliable, and secure. They are compatible with all Radio Key®proximity readers. Radio Key® proximity credentials use proven reliable technology, offering consistent read range, unaffected by body shielding or variable environmental conditions. Radio Key® supports formats up to 40 bits, with over 1 trillion possible codes. Radio Key's® passive (no-battery) design allows virtually unlimited reads.

Secura Key's Radio Key® proximity cards can be used for diverse applications such as access control, biometric verification, cashless vending, network log-on security, automotive vehicle identification and time and attendance, simply by using the card number as a reference to an external database.

The Radio Key® ISO Card (RKCI) offers the ability to add photo identification directly on the credential. The Radio Key® ISO card is a standard CR80 form factor, and it also meets strict ISO 7810 dimensional and thickness standards for use with direct image and thermal transfer printers. The ISO Card can be carried with credit cards in a wallet or purse. Use it with a strap and clip as a photo ID badge. It can be slot punched vertically or horizontally for easy use. The Radio Key® ISO Card is strong, flexible, and resistant to cracking and breaking. Available options include an unencoded magnetic stripe. External laser engraved card numbering is included.

The Radio Key® "Clamshell" Card (RKCM) can stand up to rough usage while providing superior read range. The clamshell card has a standard CR80 form factor, with a thicker rugged ABS card body which also allows thicker antenna windings than the ISO card, resulting in superior read range. The clamshell card can be carried with credit cards in a wallet or purse. It includes a molded slot for a strap and clip allowing it to be used as an ID badge in a vertical orientation. Available options include an adhesive-backed graphics quality PVC label, which can be used with direct image and thermal transfer printers to add photo ID capability to the card. External laser engraved card numbering is included.
