Have you heard the term RFID CHIP? Have you noticed that on new bank cards it has the following symbol somewhere:
:
This mark means that the card is equipped with easy payment technology using an RFID CHIP inside the card. 
In short, its holder can pay up to 25 euros at any store that supports this technology by simply touching the card to the terminal (POS) for 1 second WITHOUT entering the personal security PIN number of their card.
Behind the veil of this convenience, however, lies the following vulnerability.
The card has all our information electronically encoded in the chip (Name, Address, card number, account balance, etc.) and can provide at any time, wirelessly and without the user's knowledge, personal information and banking data... and it can even be detected remotely!!!
It's easy and one can easily find the tools on Ebay...
The process is simple, with a special RFID CHIP reader which is used as if it were the terminal (POS) it deceives the card and it gives all the information it has registered!!!
And then with a magnetic card reader (anything that has a magnetic strip…!!!) he clones the card…
What can someone do with this information? since he has cloned our card from shopping at restaurants and stores to internet subscriptions and God knows what else!!!
While the cardholder is quiet and has the card in his wallet, someone else will be eating and drinking in his name!!!
As incredible as it may seem with a simple mechanism that can be easily hidden inside an envelope, a thief can steal the credit card details of his unsuspecting victims simply by approaching their bags and wallets.
THE SOLUTION: Wrapping the card with 2-3 layers of aluminum foil is enough to block the specific frequencies and prevent eavesdropping…
