Safe online banking
Commerzbank uses the latest Internet security measures. But we also need your help to protect you. Always be vigilant when it comes to your online banking.
Innovative TANs
Your security comes first
With our photoTAN we have introduced new and innovative security measures. Your advantages:
- Encryption ensures maximum security
- No need for paper-based TANs anymore
photoTAN: Tomorrow's technology on your mobile phone today
The photoTAN is an image of small dots (approx. 1x1 inch) that is sent to you by Commerzbank and generated on your PC screen. This image contains the transaction data. You can then scan the graphic using your mobile phone or an additional image scanner. The software decodes the image data and displays your transaction data (e.g., amount and name of the recipient of a transfer) as well as a seven-digit transaction number on your phone or reader. By entering this TAN via the PC, the transaction is released.
If you do not have a mobile phone suitable for the Commerzbank photoTAN app, you have the option of purchasing an affordable scanner with us.
photoTAN does not require the installation of additional programs on the PC and is compatible with any mobile network provider. You only need to download the certified photoTAN app from Commerzbank.
