Isonas Proximity Cap Tag with Adhesive Backing, RFID, 125khz, PVC Construction

No. The Isonas proximity cap tag is a 125 kHz RFID credential, so it only reads on low-frequency 125 kHz proximity readers. A 13.56 MHz smart card reader will not see it at all. Check what frequency your reader head runs before ordering these for a site.

That is exactly what the Isonas cap tag is built for. It's a small adhesive-backed RFID disc that turns an item you already carry into a credential, so student ID cards, books, laptops and cell phones all become readable at the door. Useful in schools and multi-tenant buildings where you don't want to hand out a second card.

Operating range on the cap tag is -10F to 120F. That covers most exterior openings in temperate climates, but a credential left in a vehicle in a deep-winter or desert-summer region can run past both ends of that band. The body is PVC, not a potted or ruggedized housing.

Metal is the limitation with any 125 kHz proximity credential, including the Isonas cap tag. Low-frequency RFID detunes when mounted directly against a metal surface, so on an aluminum laptop lid or a metal-backed phone you should apply the tag to a plastic case or a non-metallic area. On paper, plastic and card stock, which is what the tag is intended for, it reads normally.

Pick cap tags when the user already carries something you can attach a credential to, or when you're tagging assets rather than people. They're small, stick on, and cost you nothing in extra items to carry. Choose a standard prox card when you need a photo ID, a printed badge face, or a slot punch for a lanyard. Both read on the same 125 kHz head, so you can mix them on one system.

White PVC. The flat white face takes a label or a handwritten ID number, which is how most facilities track which tag went to which person or asset. Only one finish is offered, so a fleet of them will all look the same.

It's a commercial access control credential. Isonas cap tags are sold as credentials for hardwired electronic access control systems, so the typical buyer is a security integrator or a facility standardizing badges across a campus, not a homeowner with a single smart lock.
