No, your kids do not need to constantly be in the Costco.
Having said that, this will probably piss me off. Why can’t the cashier do this and deny at the time of purchase.
Costco’s customer friendliness is why I shop there, and this is not customer friendly. Seems like a bean counter had a brilliant idea. /s
As for the customer friendliness of the proposed scanner, in my mind it depends on how quick and easy it is. If it's not too much of a slowdown relative to the current "flash my card at the staff person", then I don't think I'd mind it. However, if it starts causing lines to get in, yeah that's going to be a problem.
Additionally, I agree with the other commenter that, just from the details as provided, I don't even see how the proposal will solve the problem. A scanner will check that the card is a valid card, but unless it's paired with some kind of facial recognition, I'm not sure how it will prevent card sharing.
Of course your picture is on your card but I think we would all agree that a picture on a 3x2 credit card that can be B&W is inferior to the color picture displayed on an ipad. Having an associate look at a picture on the back of a credit card is slow.
It depends on store location but they have always had varying degrees of checking that you are the owner of the card. Costco makes a majority of their profit from Membership fees, hence the desire to enforce the long standing rule.
I ended up in a shouting match with the tire center manager who claimed I was in a "car accident", and thus my road hazard warranty was void after I took a nail on the freeway. I was not in a car accident, I would have known -- I was there.
30 minutes of my life I'll never get back grappling with him and the store manager -- for them to try saving a $90 pro-rata credit. My tire business has been pulled out of costco after like 25 years. It's getting tough to justify the rest of the membership. It's always a shopping hellscape there, and everyone is rude/grumpy.
