JFBAO - Buying Guide

Features

• THE SMART WAY TO PROTECT YOUR CONTACTLESS CARDS - Simply place a single JFBAO RFID blocking card in your wallet or purse and you're protected. No fiddling about with individual sleeves. No need to fork out for a new wallet or purse. You can carry on using your contactless cards as normal. Simple and effective. Every single card is tested before it leaves the factory guaranteeing its effectiveness. Any problems or questions, let us know and our customer service team will help you out.
• HOW DOES IT WORK? - The JFBAO card contains an antenna and chip. When radio waves from an incoming scan pass through your wallet, the card draws power from the waves and creates a jamming signal.
• HOW LONG DOES IT LAST? - Forever! Because the JDBAO card draws power from radio waves, it doesn't contain a battery. Please note it is slightly thicker than a standard credit card due to the internal circuit, 0.76mm thick instead of 0.9mm (barely noticable). The JFBAO RFID blocking card doesn't affect phone signal, bluetooth, WiFi, or any of your other phone functionalities (except NFC) so you can use it in a phone card case without issues.
• HOW DO I KNOW IF IT WORKS? - You can test it yourself! The easiest way is at a self checkout at a supermarket. When you go to pay, stack this card on top (or bottom) of your payment card and place on the contactless reader. The terminal will usually then throw an error message.
• A Thoughtful Gift for your Family and Friends - Offer your family and best friend a safe and dependable way to protect their credit cards or passports, by giving them a small, but thoughtful gift
