NTAG 424 DNA cards are contactless RFID badges that operate in the HF-band at 13.56 MHz. They follow standard ISO 14443 A for proximity cards. They also offer maximum interoperability in the NFC infrastructure, thanks to compliance with the Near Field Communication Forum Type 4 protocol.
They are equipped with the Secure Unique NFC (SUN) message authentication mechanism, which is enabled for every reading performed by NFC devices. Furthermore, data protection is guaranteed by crypto-secure authorisations.
NTAG 424 DNA cards are suitable for several applications in smart cities, including attendance control at companies, document authentication and loyalty programmes.
They are available in PVC, PETG and wood, in the following sizes: 86 mm x 54 mm x 0.86 mm for PVC and PETG, 86 mm x 54 mm x 1.3 mm for wood.
