Review: These work. I did the research for you. How to tell? Before you scan your next purchase at a card machine, tell the teller you want to try something, put the rfid blocker over your card and attempt to pay. It doesn't scan. Bought 2 packs of four and very happy with purchase. Won't be useful for younger people who use face recognition apparently (as per my kids). Would definitely recommend. and teller at machine wants some too :)
