Types of POS systems

The market for POS systems is ever-growing but the different systems can be distinguished by the main industries to which they cater:

Also, some providers such as Epos Now have maximised their market offerings by putting together software and hardware packages for each of these industries.

POS systems differentiated by hardware

1. iPad-compatible POS systems

iPad POS systems work by turning Apple’s flagship tablet into a touchscreen POS terminal using software installed via the App Store. Other devices can be connected via Bluetooth or GPRS. Generally speaking, POS apps tend to be free as standalone software, however, some providers sell complete hardware packages including
card readers, receipt printers, routers, and even the tablet devices themselves as part of a bundle.

At, we help you understand the differences between POS iPad providers and how they work.

2. Android/other tablet-compatible POS systems

Apple may rule the tablet market, however, this does not mean that POS systems are limited to the iPad. In fact, Android is just as accessible for POS, if not even more so. Furthermore, the main POS providers have long been offering software that is compatible with both Apple and Android. Indeed, all providers that we mentioned above can be used with Android devices as well as iPads.

3. POS terminal systems

Of course, you are not restricted to using tablets or smartphones with modern-day POS systems. Several providers also offer purpose-built touchscreen units that look like desktop monitors but store customised software and offer connectivity to the other hardware devices on your systems such as receipt printers, card readers, and WiFi devices.

What are cash register systems?

Cash register systems are full POS systems that consist of several components:

  • Cash register program
  • Computer unit (terminal)
  • Card reader
  • Receipt printer
  • Cash drawer
  • Extra handheld terminals (optional)

These systems can typically be networked, which means that you can use one programme in several locations simultaneously while storing data in a central location (such as the cloud). This is useful for multiple retail stores or other industries where multiple sites or remote working is common.

What do cash register systems cost?

You can expect to pay over £1000 for a full package. Click here for more information on pricing and specifications.

What are mobile card readers (mobile payment)?

Thanks to mobile card readers, you can now accept payments via debit or credit cards anywhere. Card readers complement most POS systems in modern business and extend the ability of businesses to offer card payment as an option by being completely portable.

All you need is internet access, although many card readers can be used offline for a short time. Data is uploaded at a later stage once a connection is available. Connections to card readers are generally made via Bluetooth from a smartphone or tablet. All the main vendors offer contactless (NFC) payment.

While card reader providers charge fees for payments, they are not astronomical, with Zettle, Square, and SumUp offering low flat fees. Alternatively, PayPal Here operates a sliding scale, which is inversely proportional to sales volumes.

Mobile card reader providers have proven effective in the digital age, especially as their record-keeping is flexible and fail-safe. This is particularly pertinent in 2019 as Making Tax Digital regulations come in to effect in October.

What do card readers cost?

Card readers are not expensive and the main vendors don’t ask for contract terms or monthly services unless you want to take advantage of extras such as Zettle Pro, for example.

The cost of a reader roughly is between £19 and £50 in the UK.
