Credit Card chip bypass with teaspoon of sugar

Posted on May 27, 2018Categories information securityTags , , , ,

A teaspoon of sugar allegedly helps the medicine go down, however it also makes a credit card chip bypass work.

What are we talking about? a teaspoon of sugar carefully put on a chip sometimes that needs to be spread  across the chip will bypass the security of the chip. How so? Insert the card 3 times really quickly with the sugar and it will bypass chip security letting you just swipe the card.


That sounds too easy but this is due to a fallback technique in the point of sales systems where you accepts payments. The fallback technique is used for legacy purposes that then just let you swipe the card.


Do you have any ways to get to fallback you would like to share? Comment away.
