Card Security

1. Purchases in stores

With “CHIP and PIN” technology. All Cajasur cards include a chip as a security element which protects against cloning and against fraud risk by validating cardholder data in encrypted form. Therefore, you simply have to key in your personal identification number (PIN) when using the card when shopping in physical stores. This procedure makes it unnecessary for you sign the receipt when making the transaction.

With “contactless” technology. Just as secure and with the ease of making payments by simply placing your card next to the POS terminal of the store which accepts contactless payments. PSD2 section – payments of physical purchases in order to learn further details about this payment transaction.

With the CajasurPay app. To do this, at the time of purchase unblock your mobile, activate the NFC option, place it next to the POS terminal of the store and then enter your card PIN if the transaction requires it. You will be asked for confirmation regularly if you wish to continue with this service.

2. Online purchases

2.1 Secure e-commerce: when Cajasur cards make an online purchase at a secure store, the cardholder will receive an sms with a single-use password on his/her mobile informing Cajasur to authorise the transaction. If you verified your device on the Mobile Banking APP, authorisation for the transaction is carried out on the app.
