What are the rules for handling a TWIC card?

  • Protect your card by keeping it in the hard plastic case provided with your TWIC.
  • Do not place or hang in direct sunlight (for example, do not place on dashboard, visor, or hang from rear view mirror of car).
  • Do not flex, bend, or punch a hole in the card.
  • Do not carry the TWIC in your wallet, as it is subject to bending.
  • Do not laminate or apply any tape or labels to the TWIC.
  • Do not punch a hole in the card to wear it on a string; use the card holder.
  • Do not place the card near a magnet or in a strong magnetic field. Industrial magnets (e.g. scrap yards, container lifters, etc.) may damage a TWIC if it is in close proximity to the magnetic source.
