Most, if not all, guest management systems in hotels use hotel key cards. Chances are you’ve probably got a hotel key card more than once in your life to access a room. You also might have some questions about how they work and how secure they are. People generally think of hotel doors as being highly secure, when in fact the technology securing them is likely out-of-date and in sore need of modernizing. Here's a complete breakdown of hotel keycards and some info that might surprise you with how vulnerable they really are to hacking, along with some suggestions on how to modernize them.
Common Hotel Card Types
Some hotels use access cards with magnetic strips, ('mag stripe cards' for short). Magnetic stripe cards are also known as 'swipe cards'. But there are other alternatives to hotel access, such as proximity (RFID) cards, access cards with holes, photo ID cards, barcode cards, and smart cards. These can be used to access rooms, use elevators and access specific areas of the building. All of these access methods are common parts of a traditional access control system.
Mag stripe or swipe cards are a cost-effective option for large hotels, but they tend to wear out quickly and are less secure than some of the other options. RFID cards are more durable and more expensive.
Hotel lock key cards are used with door card readers installed on each door lock and can be programmed to open specific doors in defined time periods.
Modern hotel access management systems enable grouping the door locks with a number of users, providing access to the same group, as well as an audit trail of who opened the door and when. For instance, one group can have access to open the hotel lobby door or the staff toilets, but only within a certain period in the day if the administrator chooses to implement a specific window of time for access.
We mentioned earlier that smart cards could also be used to grant holders unique access to elevators. For example, if a guest has booked a penthouse suite, on a floor that should be restricted to everyday users, smart cards along with advanced door readers can make this process a breeze!
