Review on 🔒 MUTBAK Sentry Cardholder: Minimalist Design with Enhanced Blocking for SEO by Rey Hossain

I tried to scan my card without removing it from the holder but it didn't work. I've tried it 3 times so far with only one card in the holder. I had to make sure the holder was blocking the RF signal. My ticket was scanned while in my pocket at the carnival so I bought this. I have 2 credit cards, driver's license and permit to carry in a holder. They're all about the size of a credit card. I don't think you could fit much more and the card is still easy to remove.
