Five-piece NFC keyholder set

The Viator Gear ZY-213DJK-5 supplies five black keychains, each embedding an NTAG213 chip with 137 bytes of user memory. They operate at 13.56 MHz and work with any NFC-enabled phone or device. The split-ring design lets them serve as key accessories, bag tags or luggage identifiers.

Rewritable chips with lock option

Each tag can be rewritten repeatedly or set to read-only using the chip’s built-in lock function. The 137-byte capacity suits short text records such as URLs, Wi-Fi credentials or contact data. Performance stays consistent across multiple write cycles without degradation.

Epoxy-sealed stainless steel build

The 33.5 by 30 mm housings combine stainless steel with epoxy resin encapsulation, giving waterproof, shockproof and corrosion-resistant protection. Data retention is rated for up to 10 years. The tags must not be placed on metal surfaces, which would block communication.

Questions about this item

Does the NTAG213 chip draw noticeable power or generate heat when scanned repeatedly throughout the day?

The passive NTAG213 chip has no battery and draws zero power until a reader energises it at 13.56 MHz, so it produces no heat and adds no load to your phone.

What phone or device do I need to read and write these keychains?

Any NFC-enabled smartphone or tablet running Android or iOS can read and program the 137-byte NTAG213 tags using a free NFC app.

Will the stainless-steel body interfere with the NFC signal if I keep the fob on a metal key-ring next to older keys?

The supplier notes the NTAG213 keychain cannot be used on metal surfaces; keep a small gap between the epoxy face and any metal objects for reliable reads.
