This allows for more control over the locks for example, a specific card may only work on certain days of the week or time of day. However, if the card readers communicate with a central system, it is the system that unlocks the door, not the card reader alone. In the case of the hotel room lock, there is no central system the keycard and the lock function in the same tradition as a standard key and lock. The main advantages with RFID cards is that they do not need to be removed from the wallet or pass holder - as the keycard reader can usually read them from a few inches away. RFID cards contain a small chip and induction loop which the transmitter on the keycard reader can access. Main article: Radio-frequency identification Newer keycard systems use radio-frequency identification (RFID) technology such as the TLJ infinity. ![]() Many electronic access control locks use a Wiegand interface to connect the card swipe mechanism to the rest of the electronic entry system. Keycards may also serve as ID cards, or as part of an NFC system, have the code transmitted to a mobile phone to be placed into a digital wallet system such as Apple Pay or Google Pay, negating the need for a physical keycard. Keycard systems operate by physically moving detainers in the locking mechanism with the insertion of the card, by shining LEDs through a pattern of holes in the card and detecting the result, by swiping or inserting a magnetic stripe card, or in the case of RFID or NFC cards, merely being brought into close proximity to a sensor. The first commercial use of key cards was to raise and lower the gate at automated parking lots where users paid a monthly fee. Keycards are frequently used in hotels as an alternative to mechanical keys. There are several common types of keycards in use, including the mechanical holecard, barcode, magnetic stripe, Wiegand wire embedded cards, smart card (embedded with a read/write electronic microchip), RFID, and NFC proximity cards. The card stores a physical or digital pattern that the door mechanism accepts before disengaging the lock. The card typically, but not always, has identical dimensions to that of a credit card or American and EU driver's license.

When the user exits the room and removes the Key Card from the switch, another wireless signal is sent to the Receivers to open the circuits. The individual Receivers then communicate with their corresponding loads to close the circuit. When entering a room, a Key Card is inserted into the switch and a wireless signal is sent to the Receivers that control the loads in the room. Inserting a Key Card provides the energy to transmit a wireless signal to LevNet RF Receivers that control lights or other devices in the room. Energy is saved by ensuring that no devices are left on when the room is not in use. The Wireless Self-Powered Hotel Key Card Switch is designed to create energy saving solutions for the hospitality industry. ![]() It takes only minutes to install and configure. The unique ID of each Switch activates only the intended Receiver(s). Wireless Switches are primarily used to control lights in businesses or homes, but they can be used to control virtually any on/off device. Pressing the switch or inserting a hotel key card into a switch provides the energy to transmit a wireless signal that controls lights or other devices connected to LevNet RF Receivers. ![]() LevNet RF Remote Switches can control an unlimited number of LevNet RF Receivers that are in range.
