The MIFARE Classic 1K NXP EV1 27mm Tamper Proof Circular Stickers offer a practical way to extend your access control or contactless system to surfaces that don't suit a traditional card format. Each sticker houses a MIFARE Classic 1K chip operating at 13.56MHz, with a read range of up to 10cm — though that figure will vary depending on your reader's output power. At 27mm in diameter, they're unobtrusive enough to sit on the back of a phone case, inside a wallet, or on a plastic card without getting in the way.

The tamper-proof construction is the detail that makes these worth using seriously. Once applied, the sticker resists removal without visible evidence of interference — the kind of reassurance that matters when you're deploying credentials across a workforce or a managed site. They arrive pre-encoded with the standard MIFARE Classic 1K memory structure, so in most cases you can put them straight to work with a compatible reader without any additional programming steps.

Supplied in packs of 100, these stickers suit organisations that need flexible, low-profile credential options alongside their existing card-based infrastructure. If your access control system already runs on MIFARE Classic 1K, these slot in without complication.
