Mandatory upgrade of the SignErgy application by 31.3.2026.

Due to the security upgrade of the SignErgy application that enables the use of PKI devices (USB key, card) with an e-zaba certificate for logging in and working in the e-zaba business banking application, it is necessary to install a new version of the application by March 31, 2026. 

If you do not install the new version of the application by the specified date, you will no longer be able to log in to e-zaba from March 31, 2026.

The minimum version required for operation after March 31, 2026. is 3.22.000.

Please check the version installed on your computer, and if it is lower than the required 3.22.000, uninstall it and install a new one.

The new version of the application is available on the website https://www.zaba.hr/home/en/support/programs-for-downloading.
