Digital signing in RIA DigiDoc mobile application

Digitally signing documents with the RIA DigiDoc mobile app is very easy. The signing process works the same for both mobile-ID and ID-card users – follow the instructions on screen and everything will go smoothly.

Step 1: Open application and select signed files

Open the RIA DigiDoc app on your smart device and select "Files" or "Signature" from the menu. In the new menu that opens, choose "Add file" and select the documents you wish to sign from your device.

To add more files to the envelope, click the "Add more files" button. All added files will be signed at once and can later be sent as a single signed envelope. You can add as many files as you like.

Step 2: Signing

In the "Container signing" view of the RIA DigiDoc app, you can see all the documents that will be signed with this signature envelope. Once all documents have been added, click the "Sign" button.

Under “Container signatures”, you can see the names of all signers. If you initiated the signing process, only your name will appear there. If you are signing an envelope that has already been digitally signed by others, you will also see the information of those who have signed it before you.

After clicking the "Sign" button, a new window will appear where you can choose which method you want to use to give your digital signature:

Step 3: Save or share the signed document envelope

To share, click the "Share" button at the bottom of the screen. A list of different sharing methods will open—choose the one that suits you best.
To save, click the three dots in the upper right corner of the envelope selection and select "Save container". A list of different locations on your device will appear—choose the location you prefer.

Step 4: Ready

It’s really that simple! After you’ve signed the document envelope and then saved or shared it, everything is done.

With the RIA DigiDoc app, you can also open digitally signed documents or, for example, encrypt them for secure forwarding.

Step 1: Open application and select signed files

Open the RIA DigiDoc application on your smart device and from there select „Signature” from the menu at the bottom of the screen. The signing view opens, where you can choose which documents you want to sign. To add a file, click on the „CHOOSE FILE” button.

To add files to the envelope, click the „+ ADD MORE FILES” button. All attached files are signed at once and can be shared later as a single signed envelope. You can add exactly as many files as you want.

Step 2: Check and sign

In the „Container verification” main view of RIA DigiDoc, under the „Container files” option, you can see all the documents that will be signed with this signature envelope.

Under „Container signatures” you will see the names of all the signers.

If you initiate the signing, only your name will be there.

If you wanted to give your signature to a document envelope already digitally signed by others, you can also see the information of other signers here.

Make sure everything is correct and click the „SIGN” button.

A small window will appear on the screen where you can select the method of digital signature

You can sign using mobile-ID, Smart-ID or ID-card (via NFC or connecting the ID-card to a card reader connected to a mobile device).

By selecting „ID-card“, you must use an ID-card and a card reader connected to a smart device to sign, while by choosing „NFC“, you can sign contactless with the ID card, i.e. without a card reader. Read more about the NFC solution here.

Signing with ID-card using NFC

When signing with an ID-card using NFC in the RIA DigiDoc application, you will be asked for the ID-card's access number (CAN) and the ID-card's PIN2 code. The CAN number is a 6-digit code that is located under your picture on the ID-card. Enter the CAN and PIN2 code and press „SIGN“. Be careful: if you repeatedly enter the CAN number incorrectly (10 times in total), the NFC part of the card may be locked. When the CAN number and PIN2 are entered, a new view „Keep the ID-card near the phone“ will appear.

After that, hold the ID-card in front of the phone until the card is read. As a rule, the phone's NFC reader is located on the top of the phone near the camera(s). NB! If the phone has a cover around it, it may prevent contactless connection to the ID-card. If your phone can connect to the ID card, successive views will appear: Contactless connection to the ID-card -> Read the certificate -> Sign the envelope -> Signature added.

Signing with ID-card and card reader

In order to use your ID-card in the RIA DigiDoc application, you need card reader that is compatible with your smart device.

Supported card readers in Android:	Supported card readers in iOS:
ACR38U PocketMate Smart Card Reader ACR39U PocketMate II Smart Card Reader SCR3500 B Smart Card Reader SCR3500 C Smart Card Reader	FEITIAN iR301U

When signing in the RIA DigiDoc application with an ID-card and a card reader, your data is shown on the screen and you are asked to enter the PIN2 code of the ID-card.

If your ID-card is not correctly connected to the card reader or the application cannot read your ID-card data correctly, you will see an error message on the screen.

Try to insert the ID-card into the reader again and connect the card reader to your smart device

By selecting „ID-card“, you must use an ID-card and a card reader connected to a smart device to sign, while by choosing „NFC“, you can sign contactless with the ID card, i.e. without a card reader. Read more about the NFC solution here.

As a rule, the phone's NFC reader is located on the top of the phone near the camera(s), but on some Android models, the NFC reader may be above the middle of the phone. NB! If the phone has a cover around it, it may prevent contactless connection to the ID-card. If your phone can connect to the ID card, successive views will appear: Contactless connection to the ID-card -> Read the certificate -> Sign the envelope -> Signature added.
