Review on Rocketek Type C CAC Card Reader: DOD Military USB C Common Access CAC Smart Card Reader for Android Phones, MacBook Pro, iMac & Other Type C Laptops - Compatible with Credit Cards/CAC Chip Cards by Tyler Spencer

I needed a card reader for shopping at a craft fair so I bought it. The first dislike is very few instructions and only for Win or Mac OS, nothing for the phone. When connected you get absolutely nothing but a red light, nothing to show you how to process a payment when selling an item, defeating the purpose of a card reader. Back immediately. Oh, and it's made in China.
