Android Card Terminals: Smart POS Explained (2026)
Pick up a modern card machine and there's a good chance it looks more like a small phone than the chunky keypad terminals of ten years ago. Many of these are Android card terminals, sometimes called smart POS terminals. They take card payments, but they also run apps, so the same device can be your till, your stock book and your receipt printer.
Here's what they are, how they differ from traditional terminals, what they cost and whether you need one.
What an Android card terminal is
An Android card terminal is a payment device that runs a version of Google's Android operating system, adapted and locked down for payments. On top of the secure payment part, it can run:
- A point of sale app with your products and prices
- Booking, ordering or loyalty apps
- Apps from the provider's own app store
- Custom apps built by software companies
The payment side, where the card is read and the PIN is entered, stays in a separate secure area that apps can't touch. That's how these devices stay PCI compliant while running other software.
How they differ from a traditional terminal
| Traditional PDQ terminal | Android smart terminal | |
|---|---|---|
| Screen | Small, often not touch | Large touchscreen |
| Apps | Payments only | POS, booking and other apps |
| Connectivity | Phone line, WiFi, Bluetooth base or SIM | WiFi and 4G, sometimes Ethernet via a dock |
| Updates | Occasional, by the provider | Regular over the air updates |
| Typical use | Type in the amount, take payment | Ring up items and take payment on one device |
Our guide to PDQ machines covers traditional terminals in more detail.
Examples you'll come across
PAX A920 range. One of the most common Android terminals in the UK, used by several payment providers under their own branding. Our PAX A920 Pro review explains the specs.
Castles terminals. Castles makes Android and traditional terminals used by many UK providers. See our Castles card machines guide.
myPOS Android models. myPOS sells several Android based terminals alongside its simpler readers. Our myPOS card machine review compares them.
Provider branded smart terminals. Many providers, including SumUp, Square and PayPal, sell their own handheld terminals with built in POS apps. They work in a similar way, but you can only use the provider's own software and payments.

Costs
There are three parts to the cost.
Buying or renting. Provider branded terminals typically cost £135 to £149 to buy outright. Traditional merchant account providers often rent smart terminals monthly as part of a contract.
Card fees. Flat rates of 1.69% to 1.75% from pay as you go providers, or custom rates from merchant account providers.
Software. Basic POS apps are often free. Advanced features, such as SumUp's POS Plus at £39 a month or Square's Plus plans from £29 a month, cost extra.
Example: a small café taking £8,000 a month
| Setup | Hardware | Monthly fees |
|---|---|---|
| SumUp Terminal on pay as you go | £135 once | £135.20 (1.69%) |
| SumUp Terminal with Payments Plus | £135 once | £98.20 (0.99% + £19) |
| Square Terminal on the free plan | £149 once | £140.00 (1.75%) |
Assumes UK consumer cards. Amex, premium and overseas cards can cost more.
Integration with card payments and your EPOS
An Android terminal can work in three ways:
- As your whole POS. Your products live on the terminal and you ring up sales directly. Ideal for small cafés, market stalls and salons.
- Paired with a till. Your countertop EPOS sends the total to the terminal, which takes payment and sends the result back.
- As a handheld. Staff take orders and payments at the table or in the queue, synced to the main till.
If you already have an EPOS, check that it supports your chosen terminal. Our best EPOS systems guide compares the main options.
Key considerations
- Who controls the apps? Some terminals only run the provider's own apps. Others allow third party apps, which is useful if you rely on a booking or loyalty system.
- Battery life. Handhelds with printers drain faster. Check how many payments they manage on a charge.
- Connectivity. A built in SIM keeps you trading if the WiFi drops.
- Printer. Built in printers are handy but add weight. Many customers prefer email receipts.
- Contract. Bought terminals are usually locked to the provider that sold them, so you can't move them to a new provider.

Looking after a smart terminal
A few habits keep an Android terminal running smoothly:
- Install updates promptly. They often include security fixes and new card scheme rules.
- Charge it overnight in its dock or with the supplied cable.
- Use a case if it's going to be carried around a busy venue.
- Clean the screen with a soft, slightly damp cloth, not harsh sprays.
- Restart it weekly if it starts feeling slow, just like a phone.
- Keep paper rolls in stock if it has a printer.
If something goes wrong, our guide to what to do when a card machine is not working walks through common fixes.
Who it suits
- Cafés, bakeries and takeaways that want a till and card machine in one.
- Restaurants using handhelds at the table.
- Mobile businesses that need a standalone device with 4G.
- Retailers wanting a second till point or queue busting device.
If you only take a few payments a week, a basic reader paired with your phone, or Tap to Pay, will do the job for less. Our Tap to Pay guide explains how that works.
Next steps
- Decide whether you need a full POS on the terminal, or just payments.
- Check whether your existing EPOS supports the terminal.
- Compare total costs for your monthly takings.
- Check whether you're buying or renting, and what happens when you leave.
FAQs
What is a smart POS terminal?
A card machine with a touchscreen that runs apps, usually on Android, so it can act as a till as well as taking payments.
Is an Android card terminal secure?
Yes, when it's a certified payment device from a regulated provider. Card data is handled in a separate secure area, away from the apps.
Can I install any Android app on a card terminal?
No. Payment terminals only run apps approved through the provider's or manufacturer's app store, to keep payments secure.
Can I move my Android terminal to another provider?
Usually not. Terminals are normally locked to the provider that supplied them, even if you bought them outright.
Do Android card terminals take Apple Pay?
Yes. They accept contactless cards and mobile wallets, including Apple Pay and Google Pay, as well as chip and PIN.
Is an Android terminal better than a phone and card reader?
For busy businesses, usually yes, because it's a single standalone device. For occasional sales, a phone with a reader or Tap to Pay is cheaper.
How long does an Android card terminal last?
Most last several years with care. Over time, providers stop supporting older models as security standards change, so ask how long your terminal will be supported before you buy.
