I have a season ticket and am always very careful not to get it anywhere near magnets or devices. On three occasions at my local Virgin station, the ticket has been rejected with code 08 which apparently means "gate failed to recode ticket correctly". Any subsequent tries with the ticket return code 09 "damaged or corrupted ticket", meaning I have to get a reprint. Do the ticket gates actually write data to the ticket each time? Could it be possible that it is the ticket gate corrupting my ticket?
