A technician is troubleshooting why a smart card reader at a secure entrance fails intermittently. Users can sometimes enter, but other times the reader does not respond. What should the technician check first?
Trap 1: Update the smart card reader firmware
Firmware updates are less likely to be the cause of intermittent physical failures; the issue appears hardware-related.
Trap 2: Replace the smart cards for all users
If the problem is with the reader, replacing cards will not solve it; the issue is likely at the reader end.
Trap 3: Reconfigure the access control software
Software reconfiguration is premature without ruling out physical hardware issues first.
- A
Update the smart card reader firmware
Why wrong: Firmware updates are less likely to be the cause of intermittent physical failures; the issue appears hardware-related.
- B
Replace the smart cards for all users
Why wrong: If the problem is with the reader, replacing cards will not solve it; the issue is likely at the reader end.
- C
Check the cabling and connections to the reader
Intermittent connectivity often points to loose or damaged cables; verifying physical connections is a quick and effective first step.
- D
Reconfigure the access control software
Why wrong: Software reconfiguration is premature without ruling out physical hardware issues first.
