Cryptographic use

The card's chip stores a key pair, allowing users to cryptographically sign digital documents based on principles of public key cryptography using DigiDoc. While it is possible also to encrypt documents using the card-holder's public key, this is used only infrequently, as such documents would become unreadable if the card were lost or destroyed.

Under Estonian law, since 15 December 2000 the cryptographic signature is legally equivalent to a manual signature
Signature

, or at public kiosks. This process usually takes less than a few minutes and the ticket is instantly active from the moment of purchase.

Customers also have the option of requesting e-mail or SMS notification alerting them when the ticket is about to expire, or of setting up automatic renewal through internet banking services.

To use the virtual ticket, customers must carry their ID card with them whenever they use public transport. During a routine ticket check, users are asked to present their ID card, which is then inserted into a special device. This device then confirms that the user holds a valid ticket, and also warns if the ticket is about to expire. The ticket check usually takes less than a second.

Ticket information is stored in a central database, not on the ID card itself. Thus, to order a ticket, it is not necessary to have an ID-card reader. Ticket controllers have access to a local archive of the master database. If the ticket was purchased after the local archive was updated, the ticket device is able to confirm the ticket from the master database over GSM data link.

 since 2004, Estonian citizens who possess an Estonian identity card are able to use that as a travel document within the EU, to Iceland, Macedonia , Norway, Switzerland and Croatia instead of a passport. However, non-Estonian citizens who hold an Estonian identity card are not able to use it as a travel document outside of Estonia within the EU. Since 3 September 2007, newly issued ID cards to EU/EEA citizens allow them travelling inside the Schengen area.
