Concepts of the world of banking identity

What is banking identity?

Banking identity is a digital verification of a user's identity that is simple, secure, free and works from anywhere. Clients of some banks can use this method, as well as to log in to their online banking, to log in to state authorities (NIA service) and newly also to private companies (BankID service) – thanks to this solution, they can verify themselves and communicate online (and soon also sign contracts or applications). Everyone with online banking already has their own banking identity.

What is BankID?

BankID is a banking identity for private companies and their clients. It is provided by Bankovní identita, a. s., whose shareholders are ten largest banks operating on the Czech market.

What is the difference between banking identity and BankID and NIA?
  • A banking identity is the name of a method—specifically, digital authentication of a user's identity.

  • BankID is the use of banking identity for the private sector – e.g. electricity and gas providers, mobile operators, insurance companies, etc. can integrate it into their systems.

  • NIA (National Identity Authority) is the use of banking identity for the state sector (so-called eGovernment services) – citizens can use it, for example, to log in to the Citizen's Portal.

  • E-identity is an electronic identity in general that serves to uniquely identify a person in the online world.

What is the difference between BankID and electronic ID card?

The eObčanka reader is required to use the electronic ID card and is usable only within the online services of the state. With a banking identity, you only need access to online banking (username and password, fingerprint, electronic key, SMS code, etc.) to verify your identity (including access to online offices).

Banking identity security

Is it save to use a bank identity?

Yes, the use of banking identity is very secure, as it is provided by the banks themselves. The operation of these systems is highly regulated at national and also European level and under constant supervision. Private companies (when using BankID) will never see the user's password or other credentials. So you don't have to worry that if they are hacked, your password to log in to the bank could be stolen. As part of the login, the user provides data to a third party (company) based on his verified consent to the bank. The verification itself takes place in the user's bank environment (e.g. mobile key, password entry, etc.). In addition, the user himself decides which personal data he wants to share and to which he does not provide access and can withdraw these consents at any time.

What is the level of guarantee of the banking identity?

The European eIDAS Regulation recognizes 3 levels of assurance (trust) of means of identification, namely low, substantial and high. Simply put, these are the levels of how much a service provider can trust a way to verify identity. A banking identity has a significant level of guarantee – it is a so-called 2-factor authentication (name, password and authorization are entered via SMS code or biometric data, fingerprint, etc.).

Will the user know somewhere to which entities he has provided his banking identity?

All such information is available to the client in the online banking of his bank. There he clearly sees which third parties he has provided with his banking identity and to what extent.

Can I revoke my consent to share my personal data?

Yes, the client can revoke their consent to sharing at any time and thus cancel the data sharing.

Will the use of BankID not result in leakage of the client's personal data?

The transfer of personal data is technically very similar to sending money from a bank to a company's account. You log in to the banking environment and instruct the bank to send your personal data to the company, exactly and only those that you confirm. The bank does not see for what purpose it is doing this, and the company never gets to the account. They are separate systems.

Why should a bank hve an access to, for example, drivers' personal cards and other systems?

Similar to the previous question. Banks do not have access to any such information, they only verify the identity of the person.

My BankID or bank identity does not work, what should I do?

Please contact your bank.

I suspect misuse of BankID or bank identity, what should I do?

Please contact your bank immediately, as well as, for example, if you lose your payment card.

Other questions

If you choose not to share your personal information, the data will not leave your bank. They are not stored by the BankID operator itself and their transmission and security are ensured by state-of-the-art of the OpenID Connect protocol. In addition, everything is reinforced with encryption designed for the financial sector (FAPI). Several independent security audits of BankID systems are planned to test the security of the system beyond the current tests.

Is there any experience with service abroad?

Similar projects, based on cooperation between banks and the state, have been successfully facilitating the day-to-day activities of people in different countries for several years, such as Norway, Denmark, Sweden, Belgium, Canada, India, the UAE or New Zealand. Banking identity is a working and proven concept there. In Norway, for example, 90% of active residents use electronic identification and signing via banking identity.

Is it true that when using a banking identity, a data box is set up for the user?

This information is misleading. An amendment to the Act on Electronic Acts is currently being prepared, which should come into force on 1 January 2022. According to this regulation, the state automatically establishes a data box when the user uses any means of electronic identification within the National Identity Authority (NIA), i.e. vis-à-vis the state. However, if the user uses a banking identity outside the NIA system, i.e. if he uses the services of Banking Identity, a. s., the data box will not be automatically set up for him.

Why does not banking identity work for a long time already, when in many foreign countries it does?

Countries approach digitalisation in different ways, depending on a number of factors, such as the level of digitalisation of banking, the approach of the state, the relationship of the population to innovation, etc. The Scandinavian countries are the furthest away, for example, in Norway, 98% of adults aged 20 to 54 use banking identity after many years of development, with an average of 184× per year. They started in Belgium only a few years ago and already bankID is actively used by over 30% of the population and more than 150 companies.

On the other hand, other countries are still waiting for the widespread use of banking identity, if they go this way – for example, Slovakia. The time of a breakthrough in online identity verification in the Czech Republic has now come, and a big thanks goes to the Czech Banking Association and individual banks. It is important for us that the banks have come together and decided to contribute to the digitalisation of the country and help develop the level of service to citizens.

If a person has one login to a number of services, is there not a risk of its theft much more than if he uses a number of different names and passwords?

The user uses BankID to a secure login to online banking, so if he follows the basic security rules, the risk is really minimal. Such passwords should be as complicated as possible (composed of uppercase and lowercase letters, numbers and special characters) and should be changed at least 1× a year. It is necessary to enter online banking from your computer or phone and avoid publicly used wifi, watch your bank's domain and do not click on suspicious and unknown applications. We also recommend that you watch out for suspicious e-mails and prompts written in bad Czech. It is also important to regularly update the operating system and browser and use antivirus.
