Are any of your cards still magnetic? In my wallet all bank cards use chips, other cards (subway tickets, etc) tend to be wireless/NFC, the remainder (IDs, licences) are either nonfunctional plastic, or chips as well.

OK, in travels some countries probably still try to read the creditcard magstripe, that may be a problem for a part of population. Otherwise it's just like worrying about the macbook demagnetizing your floppy disks..

My railcard is magnetic only, as well as my student discount card and several store cards.

My university ID uses a magnetic strip and RFID. However the university disabled RFID usage on all of the printers, doors, etc. on day zero after people found out you could easily spoof them.

Granted, at least my important cards use chips/NFC now.
