Beyond the NFC Tag capabilities mentioned above, ST25 chips also support energy harvesting technologies to extend battery life and, in some cases, even allow fully autonomous operation without any battery at all.
The ST25T product family offers a wide range of NFC RFID tags operating at 13.56 MHz. These ICs and chips feature 512-bit to 64-Kbit EEPROM memory to store product or item information which can be retrieved at power up at any stage of the end-to-end supply chain.
Moreover, they hold Unique Identifiers and Trust25 Digital signatures assigned at the EWS stage, and include counters, data protection and tamper detection features to provide multi-layer defense against counterfeiting. Different access credentials can be assigned to different data, allowing intelligent, user-specific data access scenarios across product lifetime.
The ST25TV-eSEAL is a ready-to-use Disposable Tracking demonstration board allowing the user to assess the features and capabilities of the ST25TV series NFC tags, Type 5, with tamper detection functionality and proprietary TruST25 digital signature, as well as a dedicated ST Asset tracking app and DSH-ASSETRACKING web-based cloud dashboard to help with monitoring and streamline management of multi-technology solutions.
This solution can be used with environmental and motion sensor monitoring data to detect damage from falling, or extreme temperature or humidity conditions, and even barometer pressure sensors to detect altitude or transit in a plane and signal take-off and landing phases.
Web-based cloud dashboards allow complete end-to-end application proofs of concept, and ST offers a free asset tracking dashboard powered by AWS, which is free for customers to use for application development purposes in combination with ST sensor nodes.
