It is well established that many people have the skill of opening a traditional door lock without a correct key. This is indeed a major security issue. We can only hope that all people with the skill of opening door locks are not hackers and not interested in our home or office. Change the lock to RFID-controlled, the concern of misuse of skill is mostly gone.
Hackers will try to tamper with the RFID locking system. Good locking systems will give alarms if tampered. Compucon approved card readers and locks are tamper-proofed.
There are other opportunities for hackers to go into remotely controlled locks. Wireless would be one because wireless signals could be picked up by eavesdropping or intercepting. If the wireless signal goes to the cloud, the exposure to attackers would be widely open. On the other hand, we do not need to assume that we would definitely be hacked if we use wireless or the cloud. The probability is just higher.
RFID cards are not meant to be duplicated as the ID number is pre-built in an electronic circuit protected against duplication. Also, the ID or PIN number has many more digits than 4 or 6 used for other PIN-based devices (personal identity number). In case we lost our RFID card, we would get a replacement with a different ID or PIN number and the lost number would be invalidated. Therefore whoever picked up our lost card will not be able to use the card at all even though the person knows where we live.
We do get a higher level of security than traditional locks and keys if the system is designed and implemented by Compucon or professionals of the same level.
