La Caixa has teamed up with Telefónica, Vodafone, Orange and Visa Europe to launch what the Spanish bank claims is Europe's largest NFC mobile payments service. The three mobile operators together have an 80 percent share of the Spanish mobile phone market, Barcelona-based la Caixa said.

La Caixa will launch its NFC service with a select number of clients in January, with full rollout starting in February in time for the Mobile World Congress. The bank predicts that, within a year from the NFC service's launch, it will have signed up 100,000 users.

La Caixa customers will be able to store all of their La Caixa-issued cards on their NFC-enabled mobile phones' SIM cards.

According to La Caixa, there are currently more than 300,000 contactless point-of-sale terminals in Spain. Through its partnership with the U.S. processor Global Payments, La Caixa operates around 110,000 of those terminals.

La Caixa said it has more than 12.5 million cards in issue in Spain, of which 3 million are contactless cards. It also has 1.7 million monthly users of its mobile banking service.
