An electronic lock (or electric lock) is a locking device which operates by means of electric current. Electric locks are sometimes stand-alone with an electronic control assembly mounted directly to the lock. ... Electronic locks can also be remotely monitored and controlled, both to lock and to unlock. The simplest way to add extra security to your hotel room is with a rubber door wedge, and many travelers swear by them. They're cheap, take up almost no space in your bag, and can be set up in just a few seconds. You simply place the thin end under the door jam; then gently kick the wedge into place to secure it. The key card door lock is triggered once the magnetic strip is read and verified by the hotel door card reader. As a general rule, the motion is completed by swiping the card through the magnetic reader. RFID or proximity cards don't require the swiping motion. ... RFID cards belong to the group of contactless cards.
