Hotel Door Locks & Key Cards: What to Know | Plastek
Hotel Key Card System Options
When it comes to hotel door lock options, there are a few, including magnetic stripe key cards, RFID key cards, and smart cards, each having their advantages. Magnetic stripe key cards have been in use for nearly half a century as hotel keys, and continue to offer a cost-effective approach to access control. Assuming they're not kept as souvenirs, RFID key cards have a longer shelf life than magnetic stripe key cards, but at a higher cost. Also, hotel door locks utilizing RFID technology are sealed off from dirt and debris that might find their way into a magnetic stripe key card lock. Without wear and...
