​Banks' Tupas Identification Service allows e-service providers to identify their consumer customers using strong electronic identification. The service is also used for electronic signatures. Service providers can build a uniform Tupas interface that works with all banks, and the customer uses the same bank-specific identifiers that they use in the bank's own online services.
