CrontoSign Swiss is an App for e-banking access and transaction authentication. How it works: The login and transaction data that you enter in your e-banking are encoded in a colored mosaic. The mosaic is displayed in your e-banking and then photographed using the camera in your smartphone. The data contained in the mosaic and the associated authorization code will be decoded by this app on your phone and displayed for verification. Because your app is activated with a personal key, the mosaic on the screen can be decrypted only by your smartphone. Your smartphone does not require any Internet or mobile network connection. If needed, CrontoSign Swiss can be installed on multiple smartphones and can also be used with all banks that support CrontoSign Swiss.
