CrontoSign, an efficient technological tool


    Simple and very user-friendly, CrontoSign Swiss also meets all the criteria to guarantee you a high level of security for your transactions on BCGE Netbanking (authentication and payment signature).

The use of CrontoSign is based on a scan read of a cryptogram (mosaic). The camera in your smartphone, using the CrontoSign Swiss application, analyses the image displayed on the computer screen. The application instantaneously generates a code which, when it is keyed into BCGE Netbanking, validates the authentication.

Your benefits

  • Available in the form of a free smartphone application or of an independent optical reader
  • No need to be connected to the network
  • Works for all telephone numbers (Swiss and foreign)
  • Rapid and very easy to use
  • The application is free and no charges are made for using CrontoSign
  • Security enhanced by the reliability of the authentication and the payment signature
  • The cryptogram generated is unique to each authentication and to each user

CrontoSign functionalities

CrontoSign Swiss fonctionne sous forme d'application disponible pour iPhone (dès IOS 5) et Android (dès version 2.0)


Android AppAppStore

or in the form of an independent optical reader (has to be paid for) more specifically intended for certain customer segments (for example, for use by corporate customers, or individuals who do not have a smartphone)
