A new smartpay app could make it easier for small businesses to collect payment from customers without having to set up a till.
The New Zealand-based company which designed the app says it is vital in an increasingly cashless society.
"We call it till-to-go," Smartpay chief executive Bradley Gerdis says.
"It's a free cash register app that anyone can download and use on an iPad instead of buying a large expensive cash register system."
And Mr Gerdis says the app is easy to use.
