Programmable NFC cards

This pack contains 20 blank Honeywell NTAG215 cards with 540 bytes of memory and 504 bytes available for data. Each card operates at 13.56 MHz and follows the ISO/IEC 14443A and 18000-3 protocols. The PVC cards measure 3.35 by 2.13 by 0.03 inches and are uncoated with a black finish. No internal power source is required for operation.

Compatibility and limits

Suitable for users with NFC-enabled Android phones or iPhone XS and later models who want to program tags for automation, data sharing or access control. Not suitable for buyers who need to rewrite tags indefinitely after setting them to read-only, or for anyone using devices without NFC capability. The cards cannot function in strong magnetic fields and iOS devices can only read data passively.

Memory and write endurance

The NTAG215 chip provides 540 bytes of total memory with 504 bytes user-available and supports 100,000 write cycles over a 10-year data retention period. Once a card is locked as read-only it cannot be edited or reset, which is a fixed constraint of the chip. This specification determines whether the card fits a reusable or permanent deployment.

Questions about this item

How many cards come in one pack and what is the memory per card?

The pack contains 20 cards. Each card uses an NTAG215 chip with 540 bytes total memory, of which 504 bytes are available for user data.

What does 540 bytes actually hold when I write to the card?

504 bytes are usable. That fits a short text record, a small vCard, a Wi-Fi configuration or a single amiibo dump — not images or long documents.

Which standard governs the 13.56 MHz communication and what does it limit?

The cards follow ISO/IEC 14443A and ISO/IEC 18000-3. This sets the read range to a few centimetres and the transfer speed to the standard NFC rate.
