How long does theRFID-blocking cardlast? Does it require replacement over time?
You don't need to replace your Mighty Card RFID Blocker for its entire lifetime. Unless the card is severely bent or damaged in the microchip you do not have to replace your Card Blocker.
How can I check if my Mighty Card is working?
You can test the effectiveness of your card by holding it together with an RFID card at a point of purchase terminal that accepts tap to pay.
The Mighty Card will scramble the RFID signal making it unreadable, if however it is damaged or broken from bending of folding the card will not block the signal and you should get a replacement.
The Mighty Card also does not require a battery and runs automatically when introduced to a field of RFID signals.
