An anonymous reader writes from a report via Softpedia: "A criminal group going under the name of The CC Buddies is selling a hi-tech device on the Dark Web that's capable of copying details from contactless debit cards if held as close as eight centimeters away from a victim's card," reports Softpedia. The device, named Contactless Infusion X5, is extremely dangerous because it can copy up to 15 bank cards per second, something that may come in handy if a crook is going through a crowd at a concert or through a crowded subway cart. The device can collect data such as the card's number and expiration date. If the debit card's RFID chip stores information such as the card holder's name, home address, and a mini statement, X5 can steal that data as well. The X5 is sold on the Dark Web for only 1.2 Bitcoin (~$825), and its creators say that each buyer will receive the X5 device, a USB cable for charging and data transfers, and 20 blank plastic cards.
