What is Smart Key

Each time you log into our online banking or make an online card payment, the ČSOB Smart Key mobile app checks that it is really you. Unlike the outdated SMS codes, transaction confirmation with Smart Key is not only faster and more convenient but also completely secure. One of the features that make Smart Key secure is the encryption of data transmitted between the app and the bank, protecting Smart Key against eavesdropping.
