What technology is used in key cards?

RFID technology
Technology: RFID technology uses RF waves to read and transfer data. The RFID frequency bands utilized in cards include 125 kHz low frequency for proximity cards, 13.56 MHz high frequency for smart cards, and 860-960 MHz ultra-high frequency (UHF) for high range applications.

How do key cards unlock doors?

Before you use a key card with a magstripe, it has to be “written.” That means someone uses an encoder to magnetize the stripe. The key card can then be swiped in a card reader. This reads the magnetic field and unlocks the door if the card has the right authorization.

How is technology applied in keycards?

NFC technology is being used on credit and debit cards as well, creating a contactless form of transaction. These take advantage of the added security and encryption enabled in NFC rather than simple RFID. Some modern access control providers, like Kisi, now support these third-party NFC cards to unlock smart readers.

How do magnetic card door locks work?

When the user of the card swipes it into the card reader or places an RFID card within the appropriate proximity to the card access control device, the door automatically unlocks. In addition, employees won’t have to worry about locking the door behind them as the magnetic lock system will do that automatically.

What is a prox?

A proximity card or prox card also known as a key card or keycard is a contactless smart card which can be read without inserting it into a reader device, as required by earlier magnetic stripe cards such as credit cards and contact type smart cards. The proximity cards are part of the contactless card technologies.

How do key card doors work?

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 …

Do keycards use RFID?

Newer keycard systems use radio-frequency identification (RFID) technology such as the TLJ infinity.

What technology do hotel keys use?

RFID stands for Radio-Frequency Identification. That means that the cards have little tags inside them that communicate with a reader through radio waves. Eliminating the need to swipe the hotel key card system. Your guests will be impressed with the powerful RFID technology!

What is 125kHz?

The 125kHz proximity technology has been around since 1990 – it’s basically a physical RFID chip and when you present it to an EMI field the antenna inside is excited and responds with a signal that is identified by the reader. Further, 125kHz prox is a read-only technology – there’s little or no encryption.

What is HID smart card?

What is an HID Card? Like other proximity and RFID cards, an HID card is simply an ID card which enables proximity technology in its everyday functions. HID cards, as well as other types of RFID cards and smart cards, are popular for access control, as well as other functions like public transportation and employee ID.

What is electronic key card?

Electronic key cards are similar to ATM cards — they have an attached magnetic strip that is coded by the check-in computer and read by the lock on the hotel room door. The codes from the previous use are wiped out by the computer and replaced with a new pattern that is also sent electronically to the room lock.

How does a keycard door lock system work?

These systems require a keycard reader (installed on the door) and you gain access by either tapping your card on the reader (proximity reader), swiping it (swipe reader), or inserting it (insert reader). With keycards, users no longer need to insert a metal or traditional key into a tumbler lock to gain access.

What is an RFID door access system?

Most people have used an RFID door access system at one time or another. This combination of card reader and encoded key cards is common in places like hotels, businesses campuses, office buildings, and hospitals. At the core of this access control system is the embedded credential in each card, which can be read using RFID (radio frequency).

What is the difference between mechanical and keycard locks?

Newer keycard systems use radio-frequency identification (RFID) technology such as the TLJ infinity. Mechanical keycard locks employ detainers which must be arranged in pre-selected positions by the key before the bolt will move.

What are the different types of keycards?

Keycards have many different names. There are prox cards, swipe cards, and fobs; you may have also heard of magnetic cards, RFID/NFC cards, and even simple ID cards.
