30-piece NTAG215 coin tag set

This pack supplies thirty blank NFC tags built around the NTAG215 chip with 504 bytes of user memory. Each tag is a 25 mm white PVC disc with an adhesive back, ready to be written once or locked as read-only for long-term use. The tags suit hobbyists, developers and anyone automating tasks with a smartphone or TagMo.

Passive operation needs no power

The tags draw energy from the reader field, so they add zero load to a power supply and produce no heat or noise. Data retention exceeds ten years, and the read-write lock prevents accidental changes once a tag is finalised. Keep the adhesive side dry to maintain bond strength.

Stick on non-metal surfaces only

Adhesive backing lets you place tags on plastic, wood or painted walls, but metal blocks the RF field and kills readability. The 25 mm diameter fits tight spaces such as door frames, controller shells or automation panels. No extra wiring, reader hardware or software licences are required beyond an NFC-enabled phone.

Questions about this item

How do I install the 25 mm NTAG215 tags and what step causes adhesion loss?

Peel the backing and press the tag onto a clean, non-metal surface; letting the adhesive side touch water before or after mounting will cause the bond to fail.

What maintenance or replacement will the 504-byte NTAG215 tags need over time?

The tags are rewritable until locked as read-only; once locked they cannot be edited again, so plan the final data write carefully to avoid needing replacement.

What limit appears first during sustained use of the 25 mm NTAG215 tags?

The read range tops out at 3-5 cm, so the reader must stay within that distance for every scan; metal surfaces also block communication immediately.
