Mandatory upgrade of the SignErgy application by May 19, 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 May 19, 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 May 19, 2026.

The minimum version required for operation after May 19, 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.

For help installing the new version, see the SignErgy Application Installation Guide located on the website https://www.zaba.hr/home/en/support/instruction as well as video instructions.
