NFC stickers for everyday automation
This pack contains ten black NTAG215 stickers that let any NFC-capable phone or tablet trigger actions with a tap. Each label is a 25 mm circle of PET material with an adhesive back, ready to mount on desks, walls or personal items. They suit homeowners, hobbyists and small-business owners who want quick wireless shortcuts without wiring.
540-byte NTAG215 chip with 100 000 write cycles
The genuine NTAG215 silicon stores 504 usable bytes and operates at 13.56 MHz under ISO/IEC 14443A and 18000-3 protocols. Data stays intact for ten years and the tag survives 100 000 rewrite cycles, making it reliable for daily routines like Wi-Fi hand-off, contact sharing or smart-home scenes.
Adhesive PET discs that fail on metal
The 0.2 mm thin stickers bond to most clean, non-metallic surfaces — plastic, wood, glass or painted drywall — but the NFC field collapses on ferrous metal, so they cannot be used on steel appliances, filing cabinets or vehicle bodywork. No extra software or battery is required; the phone supplies all power during the tap.

Questions about this item
What does the 540 byte capacity actually hold in daily use?
The NTAG215 chip provides 504 usable bytes — enough for a URL, a Wi-Fi credential, a short text note or a single Amiibo dump written once.
How does the ISO/IEC 14443A and 18000-3 protocol limit range and speed?
Both standards operate at 13.56 MHz and require the phone or reader to be within a few centimetres; data rate is fixed at the NFC Forum baseline.
What surface preparation and clearance do the 25 mm stickers need?
Each 0.2 mm thick PET disc adheres to clean, non-metal surfaces; allow a flat area at least 25 mm wide and keep metal objects away to prevent shielding.
