Smartphones have long been able to accept card payments. But can a phone be a full cash register that issues fiscal receipts? Yes. Here is how it works, what you need to start and who such a till suits best.
Is it legal to use a phone as a cash register
Yes. Ukrainian law allows settlements through a software registrar of settlement operations — a PRRO. It can run on an Android phone or an iPhone. A receipt created on the phone has the same status as one from a regular cash register: it reaches the tax service online and contains all the mandatory details.
What you need to start
- an Android phone or an iPhone;
- the cashier’s qualified electronic signature (KEP);
- a business unit and a PRRO registered in the Electronic Cabinet — step by step in “PRRO for a FOP: how to register”;
- optionally, a Bluetooth printer for paper receipts.
Paper or electronic receipt
A phone till can print a receipt on a portable Bluetooth printer or send an electronic receipt — for example, as a link or a QR code — with the buyer’s consent. For coffee to go, delivery or market stalls an electronic receipt is often more convenient: no printer or paper to carry.
Who a mobile POS suits
- take-away coffee spots and kiosks in malls;
- food trucks and stalls at fairs and festivals;
- couriers who take payment on delivery;
- waiters who take orders and settle the bill right at the table;
- a backup till when the main one is unavailable.
What if the internet goes down
PRRO has an offline mode: receipts are created without a connection and sent to the tax service as soon as the internet is back. The law limits offline mode to 36 hours in a row and 168 hours a month — enough for ordinary outages and blackouts. More on the “Working offline” page.
Limits to keep in mind
- battery: keep a power bank for long shifts;
- small screen: for a hall with dozens of tables a tablet is more comfortable;
- a stable printer connection: choose Bluetooth LE models if you work with an iPhone.
