Online banking means you can access your account – by phone, tablet or computer – any time, regardless of branch opening times.
Our chipTAN procedure is extremely safe because the TANs are generated individually for each one of your transactions.
To use chipTAN, all you need is your GrimmCard and our TAN generator, which is small enough to fit into any bag.
With this procedure, the transaction data is transmitted to the generator, where you will be asked to check and confirm them before entering the TAN.
chipTAN can also be used with our Sparkassen App and various accounting software.
