Elevator security keypad
Lift keypads require clients to enter a password or PIN to get to the elevator controls. An advantage of keypads is that you don't have to give key cards or key fobs to inhabitants, making it a cost-effective choice.
However, a disadvantage to keypads is that it's simple for occupants to share their access or PIN codes with others, representing a security risk. Moreover, keypads can be awkward for bigger buildings since it requires time for every individual to type in their PIN codes, making the lift ride longer.
Elevator card readers
Another commonly utilised system is elevator key fob, lift access control, which includes swiping or scanning an elevator key card system or elevator key fob at the RFID card reader inside the lift cab. After scanning their credentials, occupants can then press the lift buttons to go to their intended floor.
Although this system is more commonly used, and it doesn't provide strong security. Since elevator key card system and elevator key fobs can undoubtedly be shared or lost, unauthorised individuals can get to restricted floors without problem. One more pitfall of lift card readers is that they frequently require serious wiring, which can become expensive, particularly assuming rewiring is required.
