What you get

This pack contains 50 round NFC tags built on the NTAG215 chip. Each coin-style tag stores 504 bytes and includes an adhesive backing for quick attachment. They work with TagMo and any NFC-enabled phone or tablet running a compatible app. Makers, collectors and hobbyists who need a batch of blank, rewritable coins for Amiibo emulation or custom automation will find the quantity convenient.

Speed and reliability

The chip reads and writes in 1 to 2 milliseconds, so data transfers feel instant during normal use. A built-in read-write lock lets you freeze a tag as read-only once the content is finalised, preventing accidental overwrites. Stored data is rated to remain intact for more than 10 years. Strong magnetic fields or direct contact with metal surfaces can disrupt communication, so keep tags clear of those environments.

Build and everyday handling

Tags are moulded from 1 mm thick PVC that resists cracking and warping, measuring approximately 25 mm in diameter. The flat coin profile sits flush on desks, dashboards or inside card sleeves without snagging. Adhesive backing holds firmly on clean, non-metallic surfaces, yet the tags can be repositioned carefully if needed. Users who need a different form factor such as larger cards or flexible stickers should look at other listings.

Questions about this item

How do I install the 25mm NTAG215 sticker and what step do people often miss?

Peel the adhesive backing, press the coin tag firmly on a clean non-metal surface, then enable NFC on the phone and hold it steady over the tag until the app confirms the write — skipping the metal-surface check is the common error

What maintenance or replacement will the 504-byte NTAG215 tag need later?

The chip stores data for over 10 years with no battery; replace only if the PVC disc cracks or the adhesive fails, otherwise no routine upkeep is required

What limit appears first when the NTAG215 tag is scanned repeatedly?

Each read or write takes 1 to 2 milliseconds, so sustained rapid scanning hits that latency before any memory or durability limit is reached
