If you have Android, you can download the digital signature to your phone as a regular file using a USB cable. Connect your smartphone via a USB cable to your computer, go to "My Computer", where removable media will be displayed, then copy the EDS (files from AUTH, RSA-...p12) to the smartphone's memory card.
If you have an iOS phone, follow these steps to download the certificate:
1. Install iTunes on your computer;
2. Connect your smartphone to your computer using a USB cable;
3. Go to iTunes, click the device button, then click "Shared Files";
4. Select the eGov mobile program from the list on the left;
5. Click "Add", select the EDS files you want to transfer, then click "Add";
That's all. Now your digital signature will always be with you, which will provide additional mobility and security. Recall that the digital signature downloaded from egov mobile is only active in the application. And if you downloaded it from your computer, you can use it everywhere.
