Following American Express, which pioneered payments via Twitter in the US, Barclays is taking the ability to pay via Twitter accounts to a potential of 13.5m Twitter users in the UK.
The service, due to launch on 10th March 2015, will let people from any bank register to make payments via Twitter, so long as they are using the Barclays Pingit mobile payments app.
To be able to pay over Twitter, people need to download and log into Pingit, register their Twitter handle and then select other Twitter users to pay using the app.
Darren Foulds, director of Barclays Mobile Banking and Pingit said: "We are always on the lookout for new and exciting ways to make people’s lives easier and customer feedback plays a big part in how we chose to further develop our apps.
"Adding the ability to pay people or a small business using just a Twitter handle brings together a social and digital experience to create a new step forward for mobile payments in the UK."
According to Barclays the Pingit app has had 3.7m downloads since launch in 2012 and over £1bn has been sent using the app. Some 57,000 businesses are currently signed up to use the Pingit service.
