photoTAN for corporate clients
Online banking is now even easier – with our photoTAN authorisation procedure. photoTAN allows you to authorise your login into the Corporate Banking portal as well as payment orders in Global Payment Plus and many other transactions, such as securities transactions, guarantees, money market loan and fixed-term deposits - securely and worldwide.
The basis of the photoTAN procedure is a coloured graphic, which you can scan with the practical photoTAN reader or via the photoTAN app on your smartphone. The two factor authorisation procedure ensures the best possible security. Initially, the reader generates a transaction number (TAN) from the photoTAN graphic. In the second step, this TAN is entered in the application, for example to authorise a payment transaction order.
In December 2016, the photoTAN was given the first place in the category "Mobile Treasury Solution" by specialist magazine TMI.
- One procedure for all – a standard authorisation procedure for your login, payment transactions in Global Payment Plus and for other transactions in the Corporate Banking portal
- Payment orders from Global Payment Plus can also be authorised worldwide via your smartphone
- Practical photoTAN reader for scanning
- photoTAN app for smartphones available in the App Store or Play Store free of charge
- Security through the two factor authorisation procedure
1. Open www.corporates.commerzbank.com and log in with your participant number/username and PIN (the PIN was sent to you separately when you first registered for the Corporate Banking Portal).
2. Click on "photoTAN" in the header
3. Click on "Set up" next to the photoTAN entry
4. If necessary, click on "I would like to order a photoTAN reader"
5. Enter the number of readers, select the account to be debited and click "Continue"
6. Confirm the order by clicking on "Release with payment"
Alternatively, you can use your smartphone as a reader. To do this, simply download the free photoTAN App and order the activation letter as described above by setting up the photoTAN.
After setting up the photoTAN or ordering the reader, you will receive an activation letter and the reader after 2 to 3 working days, which must then be activated (see tab "Activation").
A reader costs 29.90 euros including VAT and can store up to 8 activations of different participant numbers for one person. The device automatically recognizes for which participant number a TAN has to be generated based on the TAN graphic that gets scanned. It is not allowed to share a reader with multiple people.
General functions of the reader
Button A: Press and hold the button for at least 2 seconds to switch the device on or off, depending on the operating state. Regardless of this, the device switches off automatically after a certain time.
Button B and C: Depending on what you are doing with the device, these buttons trigger different actions. The respective action is displayed above the button on the screen of the device.
There is a camera on the back of the device, which scans the photoTAN graphic. You will see the image taken by the camera on the device’s screen.
TAN read mode
After a successful activation, the reader automatically switches to TAN read mode each time it is turned on. The built-in camera attempts to read a photoTAN graphic in order to generate the corresponding order data and a TAN. You can see the image of the camera on the screen of the device.
As you did during activation, point the reader at a photoTAN graphic until it is fully displayed within the mark on the screen. It is best to hold the reader 10–20 centimeters away from a graphic. Try to hold the reader parallel to the graphic being scanned. As soon as the reader detects the graphic, the TAN required for release is displayed on the device display.
