OPTIGA™ Authenticate NFC solutions
Secured, intuitive experiences with Infineon’s NFC solutions
Near field communication (NFC) tags, also referred to as NFC sticker tags or NFC smart labels, are a short-range RF technology that use a base frequency of 13.56 MHz. It is a standards-based, secured contactless communication technology that enables devices that are close to each other to exchange data with just a tap. Today, NFC is enabled in a billion-plus smartphones and enjoys native support from smartphone OS platforms such as iOS and Android. This massive device adoption coupled with ease of use has fuelled widespread deployment of NFC tags in a growing number of commercial and consumer applications.
Infineon is a leader in the delivery of NFC-enabled secured, contactless solutions for payment, ticketing, and identification applications. To help customers easily embed NFC into their applications, we offer the OPTIGA™ Authenticate NFC family of products. These solutions deliver best-in-class security in a variety of packaging options suited to standalone tag applications and embedded NFC use cases.
- Contactless communication technology based on 13.56 MHz RF field
- ISO/IEC 14443 Type A
- NFC Forum Type 2 and Type 4 tag types
- Standalone plain tags and secured NFC tags for stickers
- Embedded NFC-I2C bridge tags for IoT devices
- Multiple user memory options for NDEF data storage
- On-chip high capacitance to enable small antenna designs and improved RF performance
Infineon secured NFC tags store user data in standardized NFC data exchange format (NDEF) to allow for contactless identification processes, customer engagement applications, and the secure authentication of products and accessories. Applications can be customized and built by the user to ensure product compatibility with near field communication enabled Android and iOS smartphones.
Secured NFC smart tags are built around the CIPURSE™ open-standard security architecture, which is based on robust cryptography. This ensures for attack-resistant communication between the initiator and the target tag, thus making it difficult for counterfeiting or cloning tags.
Due to their low cost and small footprint, plain NFC smart tags from Infineon can be conveniently used to embed near field communication into mass market consumer goods and applications. NFC contactless tags can be used to create an interactive and engaging experience for consumers with the simple tap of their smartphone.
The Infineon NFC chip used in plain NFC tags can be uniquely configured by the user to allow for full product compatibility. Plain NFC solutions can be used with open memory access or password protected access which is controlled by authentication procedures. Non-secure NFC tags offer a rewritable memory for simple reconfiguration, or they can be locked to prevent further changes. They also offer a unique serial number and anti-tearing support.
NFC bridge tags (NBTs) are dual-interface tags that bring contactless capabilities to IoT devices for touch-and-go mobile phone experiences. NFC bridge tags have a contactless passive NFC interface on one side and a contact-based I2C slave interface on the other which connects to the MCU of the IoT device.
Our OPTIGA™ Authenticate NFC family of NFC bridge tags is designed for today’s conventional applications like Bluetooth pairing and – more importantly – for upcoming applications like device activation and device configuration. 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.
