You have a myLowes card that has a barcode on the back? They scan my card at checkout or I scan on self service. Never been a problem but who knows...I was in Lowes today for a few items and they wanted to scan the back of my drivers license to get a military discount. My Lowes card has already verified my veterans status. I told them the few cents discount wasn't worth scanning my license and I would shop at Home Depot next time.
