I am already aware of the RFID I have been using the slip covers for a few years now. I very much like the travel belt its light and comfy, I love the positive sayings on the RFID slip covers too and even one for my passport:)... Its a great package for a super price to protect my travel documents and all my cards being credit cards or even my drivers license... I will use this at home as well as travel since I hate caring a purse will use it for everyday around town:)
