What is Smart-ID?

Smart-ID is the new generation electronic identity. The solution is developed to use conveniently on smart devices, while still keeping high level of security. Smart-ID is the easiest, fastest and safest way to authenticate customers online.

Smart-ID utilizes the user's smart device as the tool for user authentication and electronic signing. Smart-ID can be used simply on a modern smartphone or a tablet, no special SIM-cards or card-readers are needed. 

Why to add Smart-ID to your e-service?

Smart-ID can be used to authenticate user in different e-services (e.g. internet bank) or to provide electronic signatures. Smart-ID signatures are compliant with eIDAS which means they are recognized in all the European Union's member states. 

SK is building Smart-ID service as an international scheme, therefore, eID issued in one country can be used in another as well. So, in the future, Smart-ID could be the user’s key to many e-services across the EU.

Smart-ID is based on known and proven principles of public key cryptography. Compared to other possible user authentication technologies, such as PIN-calculators or one-time-use PIN-codes sent over the SMS channel, the PKI and digital signature approach gives the following benefits: high level of security, non-repudiation of operations, strong authentication and signatures recognized all over the EU. Smart-ID solution uses advanced cryptographic methods to protect the user's private key.

Smart-ID uses two factor authentication, it can be used in combination of what the user has – smart device – and what the user knows – PIN codes.
