They are literally already doing this. A couple weeks back at Costco, the self checkout lanes had an employee at every one of them checking your ID against your member card. They then would scan your stuff. They still had someone at the exit checking your receipt.
The labor spend on preventing you from sharing your member card and then STILL verifying your receipt against their own employees seems like a massive waste.
The price of cameras and gait analysis is well under the cost of even one year of a full time employee, which is why they are doing it. If they can hire even one less employee it is a win for them.

Not to mention the untold amount of money wasted on extra camera surveillance and all kinds of algorithmic gait analysis and tracking shit.
