EMV Parameters and EMV Keys Rotation

It is a common mistake to think that EMV certification process includes only two stages such as host certification and terminal certification. In the reality the situation is a little bit more complicated, there are two more important components which you need to consider: handling of EMV parameters and EMV application keys. These two components are extremely important for payment processing systems which are integrated with several acquirers.

What is the function of the EMV parameters and EMV keys? They are needed to organize the proper exchange of the information between the chip on the payment card and the EMV kernel of the payment terminal. Usually a configuration file, which includes application IDs, application parameters and keys for them, is stored in the terminal. And there is a very slight possibility that you will have to change EMV parameters at some point.

On the contrary, EMV keys should be changed on the regular basis. Sometimes EMV keys rotation can be done through an API provided by the processor, but it is important to realize that you will need some time in order to develop the respective logic which will be responsible for EMV keys rotation. There are two possible options: rotation of the EMV keys can be either embedded in the terminal management system or it can be the functionality offered by the payment gateway you are using.

One more important thing which should be mentioned is the example of the modern payment processing software which can provide you with the required EMV functionality. Consider UniPay Payment Management Platform, this is a modern, flexible payment processing solution which will meet the requirements of your business and help your business to succeed.
