A key card lock is a lock operated by a key card, a flat, rectangular plastic card with identical dimension to that credit card. Nowadays, most of hotel use Radio Frequency Identification Cards (RFID) or key card for door locks as the replacement for traditional keys.The hotel card key system was designed in the principal to enhance hotel security and upgrade hotel services. By using magnetic stripe card, guest are able to open their door room by inserting card to omit inconvenience by using traditional keys and it is unable to copy.
Benefits of using key card
- Set the time frame of use. Let say a guest has paid for a night and is due to checkout the next day at 1pm. Even if he manages to evade the front desk employee after check out, his card would not work and he has to renew and pay for another night at reception.
- Prevent key duplication. No doubt RFID can be hacked. However, with a physical key, a visit to a nearby key duplicating service will get you the key for the room.
- User management (permission). Housekeeping can only open the doors for certain hours. However, for the bigger hotels, only floor managers and above have the right to open guest room doors. Each door opening is registered into the system (the memory in the door slot) and if there is missing objects happen, the hotels can call up the time stamp and reconfirm with CCTV.
- Power management. Newer systems which only allows the specific room key to power that said room can save electricity.

How does the wireless hotel key card room locks communicate?
In general, the doors are not communicating with the server. It means there is no wireless technology involved. The room number is stored on a chip within the battery-powered lock set itself. Every lock has a specific ID that can only be changed with special device that is connected to the lock directly. The cards are only programmed that way that there is a date until they are valid for being used as key. If someone steal and try to use the card after the time of booking, the lock denies access even if the card has worked before simply because the date passed until it has been declared as being valid.
