Worried about digital pickpocketing? This SaiTech IT RFID blocker card is your simple solution to protect your contactless cards from unauthorized scanning! The golden card uses advanced jamming technology at 13.56Mhz frequency to block RFID and NFC signals from reaching your credit cards, debit cards, and ID cards. It works up to 2.4 inches away, protecting cards on both sides within your wallet or purse. At the size of a standard credit card and only 0.03 inches thick, it adds no bulk to your wallet. The best part? It requires no batteries and works for life! Test it yourself at supermarket self-checkout machines - place it over your contactless card and watch the payment get blocked. Important note: it doesn't work on 100KHz to 125KHz frequency cards (like some access cards), but covers most modern payment cards perfectly. In today's contactless payment world, this simple card gives you peace of mind against electronic theft. Just slip it into your wallet alongside your cards and forget about it - the protection is automatic. It's one of those simple, brilliant solutions that makes you wonder why you didn't get one sooner!
