About

Easy, BOM-optimized NFC connectivity for any device?

Tiny, ultra-fast, and with plenty of memory - Infineon's NFC bridge tags check all boxes to enable an easy, BOM-optimized NFC connectivity for any device, and a hassle-free user experience. These dual-interface tags bring contactless capabilities to IoT devices for touch-and-go mobile phone experiences. These products offer flexible security schemes, making them ideal for applications with specific security needs, and they come in tiny packages to enable easy integration into your IoT devices.

High-performance bridge tag for ultra-fast, contactless communication?

With their dual NFC-I2C interface, these tags act as a bridge between the device you want to control (the contact-based I2C interface which connects to the MCU of the IoT device), and the phone or reader (the contactless passive NFC interface). The two get paired easily and through ultra-fast data transfer consumers can enjoy connectivity on the go.?These tags have reduced sizes to a minimum, so even small devices can be equipped with NFC connectivity. Infineon's complete product-to-solution ecosystem offers antenna design guidance to enable rapid deployment and reduce your time to market.

Easy pairing, secured product activation and device configuration?

The tags are specially designed to enable easy pairing, secured product activation, device configuration, and data logging. Typical applications include shared mobility, personal and consumer electronics, industrial equipment, and healthcare devices:

  • Keyless access and activation of shared mobility services such as e-bikes with NFC mobile phones
  • Locking/unlocking personal electronic devices, such as portable HDD drives with NFC mobile phones
  • Prevention of electronic goods theft by restricting activation to legitimate buyers
  • Healthcare applications requiring authenticated access to secured data
  • Industrial applications involving configuration and parametrization of electric relay switches, circuit breakers, etc.
