Avengers ID Cards are identification cards for the Avengers.
The cards are used for communication purposes, as tracking beacons and as ID passes to access Avengers Mansion.
They were created by Iron Man and given to the Avengers in their first tour of the mansion.
Baron Zemo's Masters of Evil captured the Wasp, took her ID card, and used it to gain access the mansion and lure other Avengers into their trap in "Masters of Evil". This led to the cards being altered so that they could "only be recognized by the Avenger user."
