Now the vast majority of banks offer their customers payment cards equipped with an NFC chip. It makes it possible to pay for purchases, goods and services in a contactless way.
In a normal situation, a certain amount limit is set, over which payment will not take place without entering a PIN. This is another layer of defense against potential intruders. Even if they take possession of the card, they will not be able to spend too much money, giving the owner time to block the means of payment.
Recently, specialists from Switzerland were able to find a serious vulnerability in Visa cards with such an NFC chip. Under certain conditions, you can make purchases for absolutely any amount without entering a PIN.
It is noteworthy that this does not require any supernatural skills and equipment. It is enough to have the same card from which you need to withdraw or spend money, as well as two smartphones, to one of which this card is tied, which allows you to pay using your phone.
At the moment of payment, the second smartphone intercepts the transaction and quickly changes its data so that, from the “point of view” of the means of payment, the PIN code is not required here. Payment is made without any problems and the request is not received. Of course, in order to implement such a scheme, specialized software is required, which the specialists, quite logically, did not share. They have already sent information about the vulnerability to Visa, so we can expect a solution to the problem in the near future.
To begin with, use a flashlight to enlighten your card and in the place where you find the strips you can make an incision. So you can very easily get rid of contactless card payments. You do everything at your own peril and risk. I do not bear any responsibility for the result obtained. Doesn't work on the card in the video anymore, so no need to gossip that this method doesn't work.
