Citibank has launched a new Facebook app that allows users to ‘pool’ credit card reward points to save up for a group purchase or make a donation.

The ThankYou Point Sharing App, which is only available in the US, builds on a service introduced last year that lets customers transfer points to each other on the bank’s homepage.

Now, ThankYou members can combine their points on Facebook to make a charitable donation, or choose from a range of rewards on

Customers start a rewards pool by naming a recipient, who must be an individual rather than an organisation, and explaining its purpose. The recipient then maintains control of all the points.

Users can promote the reward pool through their Facebook page or by inviting other Citibank customers to donate. The app can collect personal information from Facebook profiles, but Citi says it does not share any customer account information with Facebook.

PayPal launched a similar app in November that allows Facebook users to make peer-to-peer payments free of charge.

The app, called Send Money, is aimed at the gifting marker as it allows users to send an e-card with the money, but it does not offer the same group contribution function as Citi’s app.

The launch of Citi’s app signals increased competition among online payment providers, with companies seeking to innovate and integrate social media into their online services.

Visa also announced a new online wallet last year, called, which operates in a similar way to PayPal although it was not integrated into social media networks at the time of launch.

PayPal would appear to have a headstart on other brands as it is seen as a trustworthy online brand and 80% of its users actively use Facebook, but it may soon feel the pinch if the likes of Citibank and Visa continue to push for a share of the market.
