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:
ID-card via NFC
If you choose “ID card via NFC” as the signing method, you will need to use your ID card to sign. With NFC, you can sign contactlessly — without needing an ID card reader.
Learn more about the NFC solution here.
When signing with an ID card via NFC in the RIA DigiDoc app, you will be asked to enter your ID card access number (CAN) and your PIN2 code.
The CAN number is a 6-digit code located under your photo on the ID card.
Enter the CAN and PIN2 codes, then click "Sign".
Be careful: If you enter the CAN number incorrectly 10 times, the NFC functionality of the card may become locked.
Once the CAN number and PIN2 are entered correctly, a new screen will appear saying: "Hold your ID card close to the phone."
Location of the CAN number on the ID card, residence permit card, and Digi-ID card:
After that, hold your ID card close to the phone until the card reading is complete. Usually, the phone’s NFC reader is located near the top of the phone by the camera(s), but on some Android models, the NFC reader may be near the center of the phone.
NB! If your phone has a case, it might interfere with establishing a contactless connection with the ID card.
If your phone successfully connects with the ID card, you will see the following sequence of screens:
Establishing contactless connection with ID card → Reading certificate → Signing envelope → Signature added.
ID-card via USB
If you choose “ID card with a card reader” as the signing method, you will need to use your ID card along with an ID card reader connected to your smart device.
ID card readers compatible with the RIA DigiDoc app are:
Supported card readers on Android:
ACR38U PocketMate Smart Card Reader
ACR39U PocketMate II Smart Card Reader
SCR3500 B Smart Card Reader
SCR3500 C Smart Card Reader
When signing with an ID card and card reader in the RIA DigiDoc app, your information will be displayed on the screen, and you will be prompted to enter your ID card PIN2 code.
If your ID card is not properly connected to the reader or the app is unable to correctly read your ID card data, you will see an error message on the screen.
Try inserting your ID card into the reader again and reconnecting the reader to your phone.
After successfully entering your PIN2 and clicking "Sign", you will be automatically redirected back to the "Container files" view.
mobile-ID
If you choose “mobile-ID” as the signing method, you will be asked to enter your phone number and personal identification code.
Enter your phone number and personal identification code, then click the "Sign" button.
A verification code will appear on your smart device’s screen, and you will be asked whether you want to sign the documents: "Sign?"
If the verification codes match, press "OK" (Confirm).
You will then be prompted to enter your Mobile-ID PIN2 code.
After a successful signature, you will be automatically redirected back to the "Container signatures" view.
Smart-ID
If you choose “Smart-ID” as the signing method, make sure you have selected the correct country and enter your personal identification code. Then click the "Sign" button.
A verification code will appear on your smart device’s screen. Next, you need to select the correct verification code in the Smart-ID app and enter your Smart-ID PIN2 code.
Note: When RIA DigiDoc sends the initial notification, it will ask for permission. Press "Allow" so that the Smart-ID verification code can be displayed in the Smart-ID app.
After a successful signature, you will be automatically redirected back to the "Container signatures" view.
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 "Files" or „Signature” from the menu. From the opening view choose "Add files" and choose which documents you want to sign.
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: Signing
In the RIA DigiDoc "Signing the Envelope" view, you can see all the documents that will be signed using this signature envelope. Once all documents have been added, click the "Sign" button.
Under "Envelope Signatures," you will see the names of all signers. If you initiated the signing process, only your name will appear there. If you chose to add your signature to a document envelope that has already been digitally signed by others, you will also see information about the other signers here.
After clicking the "Sign" button, a new window will appear on the screen where you can choose which tool you want to use to apply your digital signature:
ID-card via NFC
If you select “ID-card via NFC” as the signing method, you must use your ID-card to sign. With NFC, you can sign using your ID-card contactlessly, i.e., without an ID card reader. Read more about the NFC solution here.
When signing in the RIA DigiDoc app using your ID-card via NFC, you will be asked for your ID card access number (CAN) and your ID-card PIN2 code. The CAN number is a 6-digit code located on your ID-card below your photo. Enter the CAN and PIN2 codes and click "Sign." Please note: If you enter the CAN number incorrectly multiple times (up to 10 times), the NFC function of the card may be locked. Once the CAN number and PIN2 have been entered, a new screen will appear saying "Hold your ID-card close to your phone."
Location of the CAN number on the ID-card, residence permit, and Digi-ID card:
Next, hold the ID-card against your phone until it is read. Typically, the phone’s NFC reader is located at the top of the phone near the camera(s), but on some Android models, the NFC reader may be located in the middle of the phone. Note: If your phone has a case on it, this may prevent the establishment of a contactless connection with the ID-card. If your phone is able to connect to the ID-card, the following screens will appear in sequence: Establishing a contactless connection with the ID card -> Reading the certificate -> Signing the envelope -> Signature added.
ID-card via card reader
If you select “ID-card via card reader” as the signing method, you must use an ID-card and an ID-card reader connected to your smart device to sign.
