Is RFID blocking really necessary
If you're at low risk, or simply don't use anything that has RFID in it, then you probably don't need RFID protection. For low-risk people that still have cards, passports, or ID you'd prefer to keep under wraps, then investing in some protection could be worth that extra peace of mind to know you're covered.
What disrupts RFID
Here are some of the most frequent causes of RFID interference problems: Environmental factors are the most common cause. In the past there were difficulties with tags mounted on metal or on containers of liquids, which interfered with the activation of the tags and resulted in them failing to respond to readers.
How do you deactivate RFID tags
If you know the security code that you need to transmit to the tag, you can send that code and deactivate it. If you don't have the code—or if it is a passive high-frequency (HF) or low-frequency (LF) tag—then the best way to deactivate it is to zap it with electricity.
