【Multi-Function Card Reader】 This card reader supports USB/USB OTG and is compatible with microSD cards. It allows for smooth data transfer between smartphones, tablets, and PCs. I mistakenly purchased this, thinking it could read XQD cards, so it is unused. - Type: USB/USB OTG Card Reader - Supported Memory Cards: microSD - Switch: ON/OFF Switch - Connection Terminals: USB Terminal - Color: Black
