Electronic Point of Sale (ePOS) equipment ensures the fast and secure processing of electronic financial transactions. ePOS terminals are one of the most complex designs in the NFC world. They must comply with strict payment standards including EMVCo LVL1 & 2, or PBOC (a scheme used in China), and PCI, as well as certifications such as the FCC Declaration of Conformity.
Often connected to a central server for inventory management and sales reports, a complete ePOS system can consist of multiple fixed terminals but also portable and battery-powered devices required to validate the payment. In the case of mobile terminals, wireless connectivity, typically Bluetooth Low Energy (BLE), Wi-Fi or cellular, is required.
ST has many products particularly suited for these types of applications: NFC readers, ultra-low-power STM32L4 microcontrollers, and our Blue-RNG Bluetooth Low Energy system-on-chip. To complete the offer, ST’s portfolio includes convenient USB-C charging and wireless charging Qi solutions.
Security has emerged as one of the 3 key areas that developers of embedded and IoT applications are thriving to improve. The STM32L5 microcontroller series is the solution and provide a new optimal balance between performance, power and security.
