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), 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.
