My mom is a member but I am not. I scanned her card's barcode in the KeyRing app on my phone. Think I would be able to have them scan my phone instead of the card to be able to purchase this?
At my costco, they greet me by name after scanning my card "Hello Mr. xxxx" (yes, my last name is four 'x's) and I'm pretty sure their register screen shows the photo on the card. So unless you look like your mom...good luck.
