DESFire®EV3, Ultralight®, JavaCard, and other chips are available. Custom sizes and specifications are available. For NFC Payment Wristbands/Bracelets/Rings Projects
The Mifare®DESFire®EV3 series chips are NXP’s current mainstream high-security CPU card chips, supporting AES encryption and multi-application partition management. The DESFire®EV3 chip features advanced contactless technology and a robust security architecture, designed specifically for modern identity recognition systems to provide reliable data protection and efficient communication in smart card environments. Designed to global standards, the DESFire®EV3 chip integrates seamlessly with existing system infrastructure while supporting secure authentication and flexible upgrades, making it suitable for long-term deployment. The D43 model features 4KB of EEPROM storage capacity and is suitable for small-value payments, 'Nar njäts'i ya tarheta, and identity authentication scenarios involving moderate data volumes. This blank card complies with the ISO 14443A standard and is compatible with all NFC readers and writers that support this protocol. This custom NFC payment tag model is suitable for mass-produced NFC tags and wristband-type products. This custom NFC payment tag utilizes high-frequency RFID technology to communicate with compatible readers. When brought near a reader, the built-in chip and antenna are powered by the electromagnetic field and exchange encrypted data, enabling secure authentication and rapid contactless identification without the need for physical contact.
