Credit Suisse TWINT uses multiple security features to make the solution as secure as possible. For example, the only way to open Credit Suisse TWINT is with your individual TWINT PIN. To further increase security, we also recommend that you configure a PIN for your smartphone.
Communication between Credit Suisse TWINT on the customer's smartphone and the retailer's terminal takes place via readers known as "beacons," or a terminal on which a QR code is shown. However, the transaction always occurs in a secure environment and not between the terminal and the smartphone. Credit Suisse TWINT does not transmit any sensitive or personal information via the terminal. Security and privacy are guaranteed just as much whenever payment is made using a QR code instead of the beacon at the payment terminal.
If you lose your smartphone or suspect fraud, it is important that you personally report it to our free 24h HELP-Line at 0800 800 488* without delay.
