As one of the developers on the first iteration of the BookMater system, I was always concerned that someone could read the credit card info. These were stored in local, unencrypted files that any of the store terminals could connect with. If you could manage to access any of the PC's hard drive, you'd find a directory full of daily transaction files from each cash register. Parsing through these for the credit card info would not be difficult.
At any rate, the old registers have since been replaced so I'm hoping they've modernized the system in this regard. I'm very glad that they still employ people who can act quickly and are taking responsible measures during this unfortunate event.
