RFID blocking wallets do not require batteries or charging, as their effectiveness does not rely on power. The lifespan of an RFID blocking wallet primarily depends on the quality and durability of the blocking material used. With regular use and proper care, a high-quality RFID blocking wallet can last for several years. However, it's important to note that over time, the blocking material may experience wear and tear, which could potentially diminish its effectiveness. If the wallet shows signs of damage or if you notice a decrease in RFID blocking performance, it may be advisable to replace it with a new one.
