Question

which of the following is true of an access card reader? they are relatively expensive devices. they can read information encoded in the magnetic strip on plastic cards. they read, write, and edit information on plastic cards. they are used to read the information in an rfid tag. i dont know yet

Explanation:

• Option 1: Access card readers are not relatively expensive; many are affordable for access control, so this is false.
• Option 2: Access card readers (magnetic stripe readers) can read info from the magnetic strip on plastic cards (like ID or access cards), which is true.
• Option 3: Access card readers (especially magnetic stripe ones) typically only read, not write/edit; that's for devices like card encoders, so false.
• Option 4: RFID tag readers are different from access card readers (unless it's an RFID access card reader, but the option is too general; standard access card readers for magnetic stripes don't read RFID tags), so false.

Answer:

B. They can read information encoded in the magnetic strip on plastic cards.
