Is The Sam’s Club Scan And Go Application Secure?

Yesterday I went to the Springdale store to purchase a 12 lb. bag of black beans. It is the only Sam’s Club store in the area with the 12 lb. bag and it is close to our church. Since I was only purchasing one item, I used the Scan and Go application to check out.  A few minutes later at my mother-in-law’s house, I noticed that the receipt on my phone was for a 50 lb. bag of potatoes. I went back to the store because I thought it was a scanning error. The black beans scanned correctly so they took my information and promised to investigate.

Today I noticed that I have two receipts. The first receipt was for the beans at 08/26/18 13:21. The second receipt was for the potatoes at 08/26/18 13:25. How does this happen? If the times are correct, I was probably in the car going to my mother-in-law’s house when the potatoes receipt was posted.

One of the oddities that caught my attention was that my phone was on the checkout screen for the potatoes. Typically when a Scan and Go transaction completes, the checkout screen is replaced with the completed transaction screen. Although credit card fraud is always a possibility, this looks like a Sam’s Club oops problem.
