The S1F4CT puts the family’s large 6.745-inch display on a mains-powered counter unit, with Ethernet and RS232 as standard and 4G as an option rather than the other way round. That ordering tells you where it is meant to live: a hotel lobby or a restaurant counter with a cable already run to it.
It is an octa-core A53 at 2.4GHz with 32GB and 2GB, Android 13, PCI PTS 6.x. The printer takes a 50mm paper roll at 80mm a second, loaded through a snap-in cover rather than threaded.
It is 217.6 x 83.7 x 88.6mm and 451g, and runs on a 9V 4.5A adapter.
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 S1F4CT can be paying very different money. Find out what yours should be.
