The wristband includes a microtag with the customer's encrypted card details, protected with the same security guarantees as normal cards (EMV system). The contactless chip connects the wristband to point of sale (PoS) systems to complete transactions just like a standard contactless card. As with cards, for purchases over EUR 20 customers will have to enter their PIN to validate the transaction. Purchases of less than EUR 20 can be made simply by bringing the device close to the merchant's PoS.
CaixaBank added that the wristband is water-proof and damp-proof, making it ideal for the summer months. The product is also covered by the CaixaProtect service to protect customers against fraudulent use.
The wristband is CaixaBank’s second foray into wearable technology. Earlier this year it launched an app to let customers follow the stock markets via smartwatches and locate branches and convert currencies using Google Glass devices.
