Sorry if this is a silly question .
How can you tell if a credit card is metal or plastic?
I just received my Visa Infinite Privilege card. Since I‘m premium member, I thought it will be metal, but it arrived in a simple thin black envelope not like other person show as metal card and the card just looks like a regular black card.
I honestly don’t mind if it’s plastic — but I’m just curious.
