When you are out and about shopping, you may not think of using your mobile phone to pay for things. But an app that was designed here in the Midlands, is proving a hit on the high street.
Today one of the app's developers has flown out to what is known as the heartland of pioneering technology - Silicon Valley in America - to try to get more investment. As Charlotte Grant reports, it will have all begun in Birmingham.
More than 50 businesses in Birmingham have signed up to a new app, which allows people to pay for items via their mobile phone.
The creators of Droplet, the contact-less payment system, are hoping to secure millions of pounds of funding in the US so the app can be launched nationwide.
Customers upload a certain amount of money to Droplet, they then send a specified amount to vendors who have signed up to this.
The benefit to businesses is they don't have to pay bank fees for the payments.

Birmingham is trialling a new app, which lets you pay for items via your mobile phone.
Droplet has been designed by two entrepreneurs in the city and is being used by more than 50 businesses so far.
Two Birmingham entrepreneurs have developed an 'app' which allows shoppers to load cash onto their phone and send payments to anyone for free.
50 businesses in the city have already signed up to the scheme which has no credit card or bank charge and no additional charge to the user or the business.
