CrontoSign Swiss is an Android app developed by VASCO Data Security, designed to provide a secure way to perform e-banking transactions. The app works by decoding a colored mosaic displayed on your e-banking screen, which contains your login and transaction data. This mosaic is photographed using your smartphone's camera, and the decoded data is then displayed on your phone for verification. The app is activated using a personal key and does not require an internet or mobile network connection. It can be installed on multiple smartphones and used with all banks that support CrontoSign Swiss.
