Five taxi firms have signed up to a Birmingham-made app which allows customers to make payments by text message.

Scrabbling around for loose change in the back of a cab could be a thing of the past, as passengers will be able to pay with their phones following the deal with mobile payment app Droplet.

A total of 2,200 vehicles run by ABC, A1 Ace, Blueline, Radio Cabs and Streamline across East Anglia, the North East, South of England and the South West will accept the payment.

Using cloud technology, passengers are now able to open the Droplet app and the driver’s listing will appear automatically.

This comes after the Birmingham Science Park Aston company agreed deals with Chiltern Railways and Airparks last year.

Steffan Aquarone, who founded Droplet with Will Grant in 2011, said: “Passengers don’t have to worry about being caught fiddling around for change or asking the driver to stop at a cash point.

“With around 2,200 taxis now offering this payment option it’s proof that there is a demand for our technology and we are already in discussions with firms in other major UK cities.”

Droplet has rolled out across Birmingham, Bournemouth, Brighton, Edinburgh, Leeds, London, Newcastle and Norwich with hundreds of merchants accepting mobile payments.

Mr Grant added: “More and more people are turning to mobile payments as they like the speed, security and flexibility. The fact that an established sector like taxis has adopted this approach proves that Droplet can bring growth and innovation to all sectors.

“If a bit of technology can make an every day chore easier, it tends to be a hit with customers in a very natural way.”

Mike Davis, owner of A1 Ace Taxis in Taunton, has been impressed with the response so far: “While it is early days, we have had a lot of interest from our customers and they particularly like the fact they don’t have to pay any additional charges. It is easy for our drivers and is ideal for replacing cash, so making them feel more secure, especially at night.”
