Those damned tickets are so fragile aren't they? They've got nothing on the Singapore EZlink card!
Electronic devices and magnets emit magnetic fields which can cause damage to Metrotickets.
Your Metroticket is a magnetic strip ticket and the magnetic coding may be damaged by magnetic fields from these devices.
These magnetic fields extend into the space around these electronic devices or a magnet and Metrotickets coming within a few centimetres may be damaged.
So how do you keep them safe?
Keep your Metroticket away from electronic devices, magnets, magnetic jewellery and bracelets.
