The system is based on a TAP sticker that attaches to the back of mobile devices and is designed to provide secure data transfers. Inside the sticker is an EMV chip containing all the data required to complete payments as if the customer were using their card.
With the contactless TAP Visa, customers will be able to make payments using by bringing the mobile device close to an in-store terminal to complete a transaction. If the transaction is over 20 euro the customer will be asked to enter their PIN code into the terminal. Customers will also receive an SMS reporting all transactions completed using the contactless TAP Visa.
La Caixa has also developed a free application to accompany the system launch, which will be available for iOs, Android and Blackberry devices. The TAP application allows users to manage their TAP Visa contactless transactions: view transactions, payment in instalments, etc.
In May 2012, La Caixa has selected Dutch digital security company Gemalto to deploy one million of the latter’s Optelio contactless EMV cards in Barcelona by the end of 2012.
