Castles payment terminals
24 models, and what each one is actually for. Castles does not sell to merchants directly — which provider puts the terminal in front of you decides what you pay for it.
Portable
S1F3
A 5.5-inch Android portable with a 100mm/sec printer and an ATEX certification — the only Castles handheld rated for an explosive atmosphere.
Countertop

The S1F3 rebuilt for the counter — same 5.5-inch screen and Android 12, with Ethernet, RS232 and a snap-in paper roll.
Portable
S1F4
The base of the S1F4 family — Android 13, a 5.5-inch screen, a printer and a Magic Box accessory for wired ports.
Portable

The big-screen S1F4 — a 6.745-inch display on an octa-core processor, with a 3350mAh battery and an optional barcode scanner.
Portable
S1F4 MAX DUO
The MAX with a second screen on the back — a 1.9-inch customer display for QR payment and confirmation.

The only Castles portable on PCI PTS 7.x — an A73 octa-core, up to 8GB of RAM and a 6.745-inch screen.

S1F4CT
The countertop S1F4 — a 6.745-inch screen on a fixed base, with Ethernet and a snap-in paper roll.
Portable

The S1F4 with a real keypad — fifteen backlit physical keys under a 5-inch screen, for fast entry and for customers who need to feel the buttons.
Handheld
S1MINI2
A pocket Android terminal — 160g, 20mm thick, contactless and chip with PIN on the screen, built for taxis and delivery rather than a counter.
Handheld
S1E2-L
A printerless Android handheld with a 6000mAh battery — built for stadiums, events and anywhere a shift outlasts a normal terminal.
PIN pad
S1P
An Android PIN pad with a 4-inch touchscreen and a physical keypad — the customer-facing half of a till that is already doing the selling.
PIN pad
S1P2
A slim Android PIN pad on Android 13 — thirteen large backlit keys, 23mm thick, IP53, with wired ports through a Magic Box.
PIN pad
S1P2-PLUS
The S1P2 certified to PCI PTS 7.x — same body and keypad, newer certification, crystal keycaps.
Countertop
N1-22
A 22-inch Android all-in-one POS — a full till that also takes the payment, usable staff-facing or as a self-checkout.
PIN pad
S2L
A multilane customer-facing terminal — an 8-inch screen with room for promotions beside the amount, and a 15-key physical PIN pad.
Portable
S2T
An 8 or 11-inch Android tablet POS with the card readers built in — one device instead of a tablet plus a terminal.

PIN pad
V1P 3.5
A wired Linux PIN pad — 220g, a 3.5-inch screen, fifteen backlit keys, and no radio of any kind.
What these cost
Castles publishes no merchant pricing, and in Australia a merchant does not buy the hardware outright in most cases — it comes with a facility. What you pay depends on the rate you negotiate with the provider, not on the terminal.
