Castles S1 MINI2 Compact Wireless Payment Terminal | 4G + Wi-Fi + Bluetooth | Android 13 Mobile POS

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.
