I worked in the head office of a similar supermarket chain, as a software developer. One of the projects I was involved in was the development and the writing of the software of an almost identical club card system.
All changes that were made to the customers' account, be it, adding or removing points, or changing personal details of that customer, were logged into a separate database. What they were before the change and what they were after the change, and which user it was that made the change.
I would make an educated guess that Tesco did the same.
Don't think that your stupidity went unnoticed.

That may have been!
That may have been the case if the numpty management, who thought they were god in that place and treated you like shit", didnt sit at my pc and log in as "admin" with a simple to remember "password"....
