How does disputing a charge work?

My company sells a refund management product that monitors returns by customer. The customer must present an ID, typically a drivers license. The retailer can set rules such that when an individual customer reaches a defined number of returns in a certain time period, then the return can be “declined” by our system. At this point, the retailer’s policy will kick in at store level - a manager override of the return being the most likely outcome.

For confidentiality reasons, I cannot tell you the names of retailers using our product, but they are out there.

I used to work in a Holiday Inn, and we got hit with no-show chargebacks all the time. I mean it was part of the daily audit. Unless it was dead slow, there was a no-show chargeback every business day.
People would make their reservations over the phone, and then tell the Credit Card company that they’d said 6pm. We generally just trusted them to not dispute it, or to believe that they couldn’t get away with it, and ate the cost of the ones who stuck us.

Yes, some of the larger department stores (Nordstrom for example) do this. I once inadvertently was the victim of this at a Macys; I bought a rather pricey dress at the NY store. Got it home, put it on to wear it, realized it did not hang correctly. Took it back, clerk looked at the seam in question and said “this was stolen!” - someone stole it, cut out the seam to remove the sensor tag, resewed it, returned it for cash. I missed the seam-pucker when I tried it on. Since I had all my receipts, I was able to get a replacement garment.
