Golden Key TPS · SimplePOS

Sells when
the line
goes down

One Android tablet on the counter. It takes cash and cards, drives the terminal, prints the receipt and opens the drawer — and through an outage it keeps selling and uploads everything the moment the line is back.

The counter

What sits on the counter

The tablet talks to the terminal, the printer and the scanner directly over the shop's own network. There is no box in the middle to buy, power or replace — and anything you already own that speaks these standards keeps working.

Android tablet

8.0 or newer, landscape, 10 inches or bigger. This is the POS — everything else hangs off it.

Card terminal

Valor or PAX on the network. Sale, void, refund and batch close. No approval can be keyed by hand.

Optional

Barcode scanner

Any USB or Bluetooth scanner in keyboard (HID) mode. Scan a product to ring it, scan a receipt to open it.

Optional

Receipt printer

Any ESC/POS printer on 80 mm paper. Network on port 9100, Bluetooth or USB — the same bytes over all three.

Optional

Cash drawer

Any drawer with an RJ11/RJ12 kick port, wired to the printer. It opens on cash sales and cash returns, and on nothing else.

Optional
The grid

Your shelf, in the order you sell it

Hold a tile for five seconds and the grid opens for arranging: drag the best sellers to the front, edit a price, add what you just started stocking. Alphabetical is not how a counter works.

A tile marked +T is taxable. One rate per shop, applied to the items you flag, and stored with each sale — so raising it never rewrites last year's receipt.

What it does

The whole counter

Ringing up, taking the money, printing the paper and closing the day — all on the tablet, with an admin site behind it for whoever is not standing at the counter.

01

Sells with no connection

A dropped line does not stop the counter. Sales queue on the tablet and upload themselves the moment the server answers; the banner says how many are waiting.

02

Terminals, not typed numbers

Valor and PAX over the shop network. There is no way to key an approval by hand, so a payment nobody approved can never be recorded as a sale.

03

One bill, several tenders

Cash, card, store card and points in any combination. Every part is collected before anything is recorded, and returns go back per tender.

04

The paper matches the screen

The printed receipt is the same five sections the tablet shows, over Bluetooth, USB or the network. The drawer opens on cash sales only.

05

Regulars by phone number

One number a cashier can ask for across the counter. Points earn on the discounted subtotal before tax, spend like any other tender, and come back when a sale does.

06

The day, counted properly

Takings by tender, returns and voids on their own lines, card batches split credit and debit, trade by postal code. Counted in the database, not summed from the last hundred rows.

07

One key per POS

Every POS carries its own key, bound to one installation. Shut one off without touching the others; a key that turns up on a second tablet is flagged rather than passing quietly.

08

More than one shop

Each shop keeps its own catalogue, cards, customers and takings. The boundary is enforced on every read and every write, not by each query remembering.

09

It updates itself

A published build is offered on the next launch, downloaded and hash-checked before Android asks its one confirmation. Never mid-sale.

10

Cash without the penny

Where the smallest coin is going, a cash total is rounded to the nearest five cents — the rule the US Treasury recommends, or always up or always down if a shop needs it. Only cash: card, store card and points still settle to the cent. What it moved is on the receipt.

Cloud

The tablet is not where your takings live

Every sale is recalculated and recorded on the server, not on the POS. Drop the tablet, lose it, have it stolen — the day's takings, the catalogue, the customers and the card batches are all still there, and a replacement tablet is set up with a QR and a key.

01

The server holds the record

The POS says what is being sold and how many; the price comes out of the catalogue on the server and is recorded there. What the tablet sends is never taken on trust, so the takings are the server's figures whatever happens to the tablet.

02

An outage loses nothing

With no line the POS records the sale itself and carries on selling. It uploads the moment the server answers, and a resend cannot bank the same sale twice — every offline sale carries its own id and the server recognises it.

03

Read it from anywhere

The admin site opens in any current browser: transactions, receipts, settlements, customers, the areas your trade comes from, and the POS log. Nothing has to be done standing at the counter.

04

Hosted by us, or by you

Run it on our servers and there is nothing for the shop to maintain. Or run it on your own Windows server, on your own network, with the data never leaving the building — the same software either way.

05

Card numbers are never stored

The terminal talks to the card network itself and masks its own numbers; the POS scrubs the log before sending and the server scrubs it again on arrival. There is no card number in the database to lose.

06

One shop cannot see another

Every shop's catalogue, cards, customers and takings are separated at the database layer — on every read and every write, not by each query remembering to ask.

Hardware is bought separately and priced on what you choose — a POS with no card terminal costs less than one with two. Everything is optional, and anything you already run that speaks these standards keeps working. Tell us what the counter needs on the form and a person answers with the figure, usually the same working day.

Put it on your counter

Create an account and we set the shop up with you, or ask for a price on the tablets and terminals first. Either way a person reads it — nothing here is automated but the acknowledgement.
