Hardware compatibility

Works with the hardware you already own

Oliver POS runs natively on iPhone, iPad, and Android today — with native macOS and Windows desktop apps coming soon. Certified for Star and Sunmi printers, every USB and Bluetooth barcode scanner, RJ11/RJ12 cash drawers, and most ESC/POS thermal printers on the market.

Platforms Oliver runs on

Use the devices you have. The same Oliver register works across all of them, with the same login and the same data.

iOS — iPhone & iPad

Native iOS register for iPhone and iPad, with Tap to Pay on iPhone built in. Runs on any modern iPhone or iPad on iOS 14 or newer.

Android — phones & tablets

Native Android app for tablets and phones running Android 10 or newer. Recommended minimum: a quad-core 2.0 GHz CPU and 3 GB of RAM.

macOS — coming soon

A native macOS register for desktop and laptop Macs is in active development. We'll publish the release date as soon as it's locked in.

Windows — coming soon

A native Windows register app for desktop and Surface-class devices is in active development. We'll publish the release date as soon as it's locked in.

Receipt printers

Certified for Star and Sunmi out of the box. Everything else either prints through your operating system or speaks ESC/POS — which covers most thermal printers on the market.

Certified — Star (Star Micronics)

First-class support for the TSP and mC-Print families over Wi-Fi, LAN, USB and Bluetooth. Plug it in, pair once, print receipts and kick the cash drawer.

Certified — Sunmi

Built-in printers on Sunmi smart POS devices (D3, V2, T2 and similar) work natively with Oliver — no driver, no extra config.

System print — AirPrint & Android print

Any printer your iPhone, iPad, or Android device already prints to also works with Oliver: AirPrint on iOS and Android's default print service. A4, Letter, 58, 80 and 90 mm rolls all supported.

General ESC/POS printers

Most thermal receipt printers on the market speak the ESC/POS protocol, and Oliver supports it. There are a lot of no-name brands out there, though, so we don't guarantee every model — quality varies.

The reliable path: install the printer using the vendor's own setup tool first, so the operating system sees it as a regular printer. Once the OS prints to it, Oliver will pick it up automatically.

Not sure if yours will work? Send us the make and model on the contact page and we'll tell you before you commit.

Barcode scanners

We work with every barcode scanner that's USB or Bluetooth and connects as a keyboard (HID). That covers roughly 99% of scanners shipped today — Honeywell, Zebra, Datalogic, Socket Mobile, and the long tail of generic 1D/2D scanners.

Scanners read barcodes in different ways and most ship pre-programmed for the common case. If you need a specific output format (a prefix, a suffix, a line break after each scan), use the configuration barcodes in your scanner's manual to program it once — Oliver will then receive exactly what you want.

Cash drawers

Oliver works with the RJ11 / RJ12 cash drawers the vast majority of the industry uses (the connector looks like a slightly smaller version of a network jack). The drawer plugs into the receipt printer's drawer-kick port and opens when a receipt prints.

That means a cash drawer is supported wherever the printer driving it is supported. If your printer is in the certified list above or sets itself up cleanly through your operating system, the drawer connected to it will too.

Keyboards & HID input

External keyboards work across iOS and Android. Plug in a USB or Bluetooth keyboard and you can type into any compatible field in the register — customer name, email, quantity, search, notes, and so on.

Under the hood, keyboards and barcode scanners use the same HID input path, so anything that talks like a keyboard to your device will talk to Oliver.

Coming later

Two things on the way. We'll publish dates as soon as we have them locked in.

macOS native app

A native macOS register for desktop and laptop Macs is in active development. We'll publish the release date as soon as it's locked in.

Windows native app

A native Windows register app for desktop and Surface-class devices is in active development. We'll publish the release date as soon as it's locked in.

Hardware questions, answered

Do I need to buy hardware from Oliver?
No. Oliver runs on the devices you already own — any iPhone, iPad, or Android phone or tablet. You can add a receipt printer, scanner, cash drawer or card reader if you want, but none of it is required to start.
My printer isn't a Star or Sunmi — will it work?
Probably yes. We officially certify Star and Sunmi, but Oliver speaks the general ESC/POS protocol most thermal printers use, and we also print through the operating system (AirPrint on iOS, the Android default print service). Set the printer up with the vendor's own software first so the OS sees it, and Oliver will pick it up automatically. We can't guarantee every no-name brand, so test before going live.
Which barcode scanners are supported?
Any USB or Bluetooth scanner that connects as a keyboard (HID). That covers the vast majority of scanners on the market — Honeywell, Zebra, Datalogic, Socket Mobile and most generic 1D/2D models. Most scanners ship pre-programmed; if you need a line break or a specific prefix, use the configuration sheet in your scanner's manual.
Will my cash drawer open from Oliver?
If it uses the standard RJ11 or RJ12 ("phone cable") drawer-kick connector and plugs into a supported printer, yes. The drawer is opened by the printer when a receipt prints, so a drawer is only supported on setups where the printer itself is supported.
Can I use a regular USB or Bluetooth keyboard?
Yes — on iOS and Android. Oliver listens for HID keyboard input, so an external keyboard can type into any compatible field (name, email, quantity, customer search, and so on). This is the same input pipeline used by barcode scanners.
Does Tap to Pay need a separate card reader?
No. On a recent iPhone or Android phone, Tap to Pay turns the phone itself into the reader — contactless cards and digital wallets, no extra hardware. For pin entry, chip cards or larger setups, pair a dedicated terminal from the hardware shop.
Does Oliver support weighing scales?
Not at the moment. "Scale" product types are on the roadmap but aren't supported in the register today. If you have a specific scale integration in mind, contact us with the make and model and we'll let you know where it sits in the queue.
Can I use the POS hardware I already own?
Usually yes. If the printer speaks ESC/POS or talks to the operating system, the scanner emulates a keyboard, and the cash drawer uses an RJ11/RJ12 cable through the printer, you're covered. Send us the model numbers and we'll confirm compatibility before you commit.

Not sure if your device works?

Send us the make and model of anything you already own — printer, scanner, drawer, terminal — and we'll confirm compatibility within one business day.
