The S1P plugs into a cash register, a terminal or a self-checkout and becomes the part the customer touches. It has a 4-inch colour touchscreen at 480 x 800, a physical keypad and a front camera for QR codes.
A quad-core at 1.3GHz with 16GB of flash and 2GB of RAM, on Android 10. All three card readers, two SAM slots expandable to four, and two SIM slots.
It is PCI PTS 6.x with EMV contact Level 2 and the full set of scheme contactless approvals. Android 10 dates it against the S1P2 and S1P2-PLUS that sit above it.
What it costs
The rate you pay is negotiated on your volume and card mix, not set by the terminal — two businesses on the same S1P can be paying very different money. Find out what yours should be.
