Ex-criminal built Theif-proof device to help protect world ATMs while still serving six year jail term

Just as Martin Lawrence said in a movie ''If, I was a thief, I would definitely know where and how to break into this building''.
Valentin Boanta is a Romanian computer specialist who is currently serving a five-year jail term after he was found guilty of supplying a gang of Romanian robbers  with gadgets with which they used to scan magnetic strip of  bank cards and used them to withdraw cash via ATM. But, he tuned a new leaf after he was cut. To my surprise, he said he became happy after he was caught.
While still serving his six year jail term, he thought of a way to help protect world's ATMs. He built his SRS, Secure Revolving System, which can help to protect cardholders against Skimmers.
Here's how the device works:

First, the cardholder insert the card into the SRS long edge. By this, Skimmers or any Skimming gadgets would find it so difficult to scan the magnetic strip at the back of the card.
