Twitter users can now donate to charity via JustGiving though a new app called giv2.it.

To donate, users need to mention the charity in a Tweet with the amount they wish to give and the hashtag #giv2.

Within five minutes giv2.it will then send the user a link to the charity’s JustGiving page, pre-populated with their donation, ready for them to enter their card details to donate.

Registered JustGiving users will just need to enter the authentication code on the back of their credit/debit card.

People using a smartphone will automatically be directed to the JustGiving mobile-optimised site.

Developer Simon Painter said: “There’s no lengthy process for signup and no one is asking for commitment. I wanted to try to create something to take that to Twitter, because I believe that it currently has no serious proposition for instant giving.”

Charities need to be registered with giv2.it and JustGiving, but if someone Tweets a donation to a charity which is not registered then giv2.it will inform the charity that they have a donation pending and direct them to the sign up page.
