elements offered by STMicroelectronics are ideal for secure payment and access control applications. These products ensure secure communication and data protection, making them suitable for contactless payment systems and secure access management. NFC technology is unlocking new possibilities every day – will your next product tap into its full potential?
Development support
even longer distances. The NFC reader generates the radio signal which powers up the NFC tags to establish a connection and allow communication.
STMicroelectronics range of NFC readers, the ST25R product family, provide multiprotocol support for 13.56 MHz communications such as ISO 14443 Type A or B, ISO 15693, ISO 18092, FeliCa, and NFC Forum protocols. The ST25 readers are compliant with the NFC Forum CR13 certification, and ensure full interoperability with mobile phones, as well as with all other NFC-enabled devices and cards. The ST25 NFC reader ICs are available with SPI and I2C interface options to communicate with a host microcontroller.
The ST25 readers are designed to be low power and are suitable for use in consumer goods and industrial flows for power and data transfer to authenticate objects, improve safety, and enhance customer experience as well as to get valuable feedback on product usage. Payment terminals equipped with the ST25 reader benefit from advanced features such as Active Wave Shaping (AWS) and Dynamic Power Output (DPO). These features are instrumental in achieving the latest EMVCo certifications swiftly, enabling designers to achieve the shortest possible time-to-market. Additionally, the inclusion of Noise Suppression Receivers (NSR) ensures compatibility with noisy displays, enhancing functionality in challenging environments.
Security is a critical aspect of NFC technology; STMicroelectronics ensures that their NFC products meet the highest standards of security. The NFC controllers and secure elements provide secure communication and data protection, making them suitable for applications such as secure payment and access control. An example is the ST25TA-E secure NFC tag for product authentication which supports Digital Product Passport and brand protection applications by utilising password-based authentication, cloning protection with ST’s Edge TruST25TM digital signature, on-chip ECDSA signature and blockchain compatibility. The NFC tags and Readers are part of STMicroelectronics 10-year longevity commitment meaning designers can confidently integrate them into products.

NFC tags can do more than just store data – they create instant, interactive experiences. For example, by embedding a web page URL or a direct app link into their onboard memory, these tags allow users to simply tap with a compatible mobile device to launch a specific web page. Whether it’s accessing a digital user manual, activating a product warranty, or downloading an app directly, NFC makes the process seamless, intuitive, and just a tap away.
Contactless electronic ticketing for mass transport systems is a popular application, use of NFC technology in this scenario allows fast access and minimal delays for users. NFC technology is also being utilised in access control systems to provide secure and convenient access to buildings and facilities.
NFC tags aren’t just for user interaction – they’re transforming production workflows too. By enabling wireless programming of device parameters during manufacturing, NFC eliminates the need for manual steps like setting DIP switches. Even more impressively, it supports “in-the-box” programming, allowing devices to be configured without ever opening the packaging. This means manufacturers can maintain a single, generic inventory and program each unit to specific customer requirements just before shipping – dramatically simplifying stock management and offering greater agility in responding to changing order patterns. Asset tracking and data logging is yet another area where NFC is being widely adopted, it allows users to audit the tracking data on a product, for example the transportation cold chain data for food products and supports Digital Product Passport initiatives by enabling secure, verifiable product histories that enhance transparency, compliance, and brand protection throughout the product lifecycle.
NFC technology is also being used widely in industrial equipment for applications such as equipment monitoring and maintenance. The ST25 dynamic NFC tags and readers offer reliable and efficient communication for industrial applications. For example, they allow retrieval of fault history in case of equipment failure, even if the device is no longer powered.
