Its the magnetic strip getting wiped by something. Common cause is a
magnetic clip on a wallet of handbag where it is kept. Another common one is
the magnetic bracelets the older folk tend to wear for joint relief etc. Can
also be done by mobile phone in close proximity. Happens very regular.
Cant it now be done at your local station. It was introduced like that about
2 years ago but it may have changed perhaps. Just ask the nice young lady on
the barrier to see if it can be done locally.

Maybe you're exposing your card too much/often/whatever to some kind of
source (e.g. magnetic field) that destroyed the data? Or your favourite
PO isn't storing the cards properly...



Just as well it is not an UK ID card then! Probably be in the Tower of
London by now about to be beheaded.
