One can make an RFID shield for a folding wallet fairly easily. Take a manila folder or something similar and cut it to tightly fit in the outside pocket. Cover that with aluminum foil, then cover that with packing tape. Place this in the outside pocket of the wallet, fold it so the RFID shield covers the contents, and cards inside are protected.
