The card is inserted into a compartment from the top of the device. The upper part of the glass is backlit (to illuminate the room number or a logo – both customizations on request) in the lower part there are 3 freely configurable backlit capacitive button (typically with ROOM LIGHTS function and buttons for setting MUR and DND). Offices have also slowly installed digital locks that integrate with key cards and biometric technology.The products is intended to be installed with the glass covers which can be customized on request. Many modern households have installed digital locks that make use of key cards, in combination with biometric fingerprint and keypad PIN options. RFID cards and key fobs are becoming increasingly popular due to their ease of use. Logs are often kept of which cards unlocked doors at what times.Ĭomputerized authentication systems, such as key cards, raise privacy concerns, since they enable computer surveillance of each entry. Which locks can be opened by a card can be changed at any time. 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.
