RFID Anti-skimming card in bamboo case. In this digital era, thieves do not even need to steal your wallet to get to your money or information. By using an electromagnetic field this anti-skimming card makes all 13.56 MHz cards (trains, buses, bank or credit cards) secure from electronic pick pocketing 2-3 cm around the card. It has the same size as a regular credit card, so it will fit easily in your wallet. A great item if you have a wallet that does not have RFID protection yet. (1,3 mm).
