A clear trend in Point-of-Sales is to replace conventional ePOS devices with tablets and smartphones executing a POS mobile app and providing the required backend and connectivity to a mobile POS terminal (mPOS). The mPOS might even provide LTE connectivity allowing them to be either a mobile payment device or a standalone unit. These terminals run the EMVCo Level 1 and 2 contact and contactless stacks as well as tamper detection and cryptography functions for PCI compliance.

Our ST25R NFC readers provide high sensitivity and antenna adaption to significantly reduce certification efforts helping to compress time to market. We also provide Bluetooth Low Energy connectivity and Qi-compliant wireless charging solutions.
