3.5. Encrypt sensitive traffic over public networks

Your Point Vx allows transmission over public networks, e.g. public internet. To protect sensitive da-
ta your Point Vx uses triple DES encryption with a unique key per transaction. On top of that all data
sent to and from the Point Vx is protected under SSL, if the processor supports SSL. To connect your
Point Vx to public networks you do not need to take any further action regarding encryption.

4. Back-out or product de-installation procedures

The software of your Point Vx could be updated remotely either automatically or manually triggered.
In the unlikely event that your newly downloaded software fails or malfunctions please contact your
TMS
operator in order to allow you to download an older version of the software.

5.1. How to change the address to the centralized log server

By default the Audit Trail is sent to a centralized log server hosted by your PSP. If you want to con-

follows.
On the Point Vx terminal Stand Alone mode
1. Select "MENU"
2. Select "Maintenance"
3. Scroll down to "LOG MENU"
