Frequently asked questions

What is the difference between reading range on metal and off metal?

The Tag-Icode-4921 is an on-metal RFID tag — its design includes a special substrate that makes it work better when mounted on metal surfaces (up to 8 cm range) compared to non-metal surfaces (up to 5 cm range). Standard RFID tags typically fail completely on metal due to signal interference, whereas this tag is specifically engineered to counteract that effect.

Is the Icode-4921 compatible with NFC smartphones?

Yes. The tag operates at 13.56 MHz and supports the ISO 15693 standard used by NXP I-CODE SLI-X chips. Most modern smartphones with NFC support ISO 15693 reading, making it possible to scan the tag with a phone. However, the effective range with a phone may be shorter than with a dedicated RFID reader.

Can the tag be reused after writing data?

Yes. The tag supports up to 100,000 write cycles, making it fully reusable. Data is retained for up to 50 years without power, so the tag is well-suited for long-term asset labelling applications.
