HID Global SlimFlex™ UHF RFID Tag (Higgs 3)



HID Global SlimFlex™ UHF RFID Tag (Higgs 3)

HID Global SlimFlex™ UHF RFID Tags are among the most advanced general purpose flexible tags available. The unique thermoplastic elastomer (TPU) housings – made from the same materials used worldwide to manufacture automobile pipes and hoses – tolerate repeated bending or torsion, while maintaining excellent performance characteristics. The durable housing safeguards embedded electronics, even under harsh conditions. Standard SlimFlex tags attach snugly to round or irregular surfaces, such as cylindrical containers, plastic pipes, helmets or even trees. These tags conform to the surface contours and can be securely attached with cable ties, industrial adhesives, rivets or screws. While the SlimFlex Tag with a washer has been designed with one reinforced hole to rivet it. This version is ideal whenever a SlimFlex tag shall be fixed with a single rivet to hang down from metal bars or be placed on a hook.

Barcode and Serial numbers are uniquely generated and assigned during manufacturing. Please contact us if you would like specific information printed and encoded on your tags.
