The S1F3CT takes the S1F3’s platform — quad-core A53 at 2.0GHz, Android 12, a 5.5-inch HD+ touchscreen, 32GB and 2GB — and puts it in a fixed countertop body with wired ports: Ethernet, RS232 and USB alongside the mobile and Wi-Fi options.
Being mains-powered rather than battery-powered is the real difference. It runs off a 9V 4.5A adapter, takes a larger 50mm paper roll, and prints at 90mm a second.
It is 217 x 81 x 73.5mm and 430g. PCI PTS 6.x, two SAM slots, and two SIM slots as an option.
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 S1F3CT can be paying very different money. Find out what yours should be.
