[FAQ] Protecting my RFID Card

March 12, 2013

RFID is a type of wireless technology, used by many organisations to provide access control for buildings.

RFID (Radio Frequency IDentification) Cards allow you to obtain sensitive information to help identify objects that have been fitted with special RF identification tags in order to easily manage assets and materials, determine access control and track inventory.

Being able to identify and account for items so quickly and easily, it is vital that we secure these cards adequately.

Here are some ideas on how to protect your RFID card;

  • Use approved RFID Protection sleeves (FIPS 201) for all RFID cards to make card skimming more difficult – http://en.wikipedia.org/wiki/Radio-frequency_identification#Shielding
  • Never display RFID card IDs in public (code usually printed on the card) as cloned cards can be produced from this alone – http://andrewmohawk.com/2013/01/27/bypassing-lf-entry-systems/
  • Don’t rely on only RIFD tags as access control to highly sensitive areas, use other factors such as biometrics in conjunction with physical tokens (RFID cards).
  • Be aware of the information being given out as social engineering attacks will usually be cleverly disguised.
  • Never assume people are authorised to have access to sensitive areas of the building. If you are suspicious it is perfectly acceptable to ask why somebody is where they are and to follow it up.
