A prepaid card and Magnetic buckles
One day when I rode on a bus, my bus ticked didn't read. I didn't know why. The bus ticket was a prepaid card and recoded the balance magnetically, and if it's put near a magnet the data may be impaired. But where were the magnet? Perhaps it was a magnetic buckle on my bag.
A few years ago I had had the same experience, and at that time the pen tablet I'd just bought was suspicious, so since then I had kept bus cards away from the tablet and other magnetic devices. But I hadn't had the idea that a bag could ever be the culprit.
