CaixaBank and Global Payments are to host a wearable financial app hackathon to be held simultaneously in Barcelona and Atlanta.
The 24-hour hackathon is an extension of CaixaBank's annual FinAppsParty, which was first staged in Barcelona in 2011.
In 2013, 150 app developers competing in 48 teams took part in the event and the chance to win a EUR10,000 first prize.
Winning projects have included apps for connecting users of near-field communication (NFC) technology, business geolocation and payment systems via social networks.
For the 24-25 October wearable hackathon, judges at each locale will distinguish the three best innovative payments applications developed during the marathon coding session.
The winners will "bridge the gap between functionality and originality in graphic image, browsing and usability for consumers and merchants," says CaixaBank.
