The Castles S1MINI2 is an ultra-compact, handheld wireless payment terminal built on Secure Android 13, giving ISOs, merchant services providers, and payment resellers a modern mobile POS to deploy at scale. Weighing just 160 g with a 4" capacitive multi-touch color display, it accepts EMV chip and NFC contactless payments anywhere a merchant does business — making it ideal for taxis and ride services, delivery drivers, outdoor vendors, market stalls, and events or pop-up retail.

With true mobile connectivity over 4G LTE, dual-band Wi-Fi, and Bluetooth 5.0, the battery-powered S1MINI2 keeps merchants taking payments on the go without a fixed connection. Built-in remote estate management, remote key injection, and real-time monitoring make it simple for distributors and processors to provision, secure, and support a fleet of devices from a single platform.

  • Accepts EMV contact chip (ISO 7816) and NFC contactless payments, including Mifare and FeliCa, for fast tap-to-pay acceptance.
  • Mobile-first connectivity with 4G LTE / 3G / GPRS, dual-band Wi-Fi (2.4 GHz and 5 GHz), and Bluetooth 5.0.
  • 4" color LCD with capacitive multi-touch for on-screen chip and PIN entry and contactless transactions.
  • PCI PTS 6.x certified hardware to keep cardholder data secure in the field.
  • Ultra-compact 120 x 66 x 20 mm body at 160 g with a built-in 2000 mAh Li-Ion battery for true on-the-go use.
