Aug 23, 2024 · Keycards offer security, ease of use, and the power to control and monitor access remotely. Traditional keys can be a hassle—they get lost, duplicated, and don't offer any real-time control. Keycards, on the other hand, come in various types like magnetic stripe cards, RFID cards, and smart cards.

- What's a keycard? How does it work? 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.
- Advantages & Disadvantages of Keycard Entry Systems. Now that you’ve learned how access cards work, it’s time to look at the pros and cons of choosing a keycard system over other types of door entry systems.
- Alternatives to Keycard Entry Systems. Given the disadvantages of keycard entry systems, it's imperative to identify better alternatives that can address these disadvantages.
- What are RFID/NFC keycards? RFID cards are most widely used in commercial office spaces. These cards (sometimes referred to as 'tags' or 'fobs') can be classified by the range they communicate (low, high or ultra high) and the way the communication happens with the reader (active or passive).

RFID stands for “radio frequency identification.” Data is stored in a microchip often referred to as an RFID tag. RFID cards have many variants, especially when it comes to key card entry systems. In fact, all key cards other than Wiegand and Magstripe use RFID technology to transfer data to the reader, but they have different working mechanisms. T...
There are three types of contactless cards or badges for key card entry systems. These can be read from a distance and do not need to be inserted into the reader. All of them use RFID protocols but use different technologies to store and read data. They are proximity cards, smart cards, and NFC cards.
NFC (Near Field Communication) cards, sometimes also called NFC smart cards, can be read using a smartphone or another NFC-enabled device. These cards contain a writable NFC chip that can be used to read and store messages, numbers, and other microdata using a NFC enabled smartphone. Technology:NFC cards communicate through radio frequency signals....
Proximity cards, chip-based smart cards, and NFC cards are all contactless cards that can be read without inserting the card into a reader. All of them are used in physical access control, but there’s a difference in the way they work.
Hybrid key cards use a combination of technologies to enable a number of specific applications. For example, a magnetic stripe card can include a smart chip, where the stripe can be used for key card access control systems and the chip can be used for storing account information and withdrawing funds or making purchases. Contact-based and contactle...
Not to be confused with Wiegand card format for transmitting data in access control systems, Wiegand cards are based on a magnetic phenomenon called the Wiegand Effect. They use low-carbon Vicalloy, a ferromagnetic alloy of cobalt, iron, and vanadium, to store a unique number that can be read by a Wiegand reader. Filaments of Wiegand wire are embed...
A magnetic stripe card, sometimes also known as a swipe card or magstripe, records credentials by modifying the magnetism of tiny iron particles embedded in a stripe of magnetic material on the card. Magnetic Recording Technology:Swipe cards store data using the 1960s magnetic recording technology used in audiotapes. When the card is swiped, the da...
A key card entry system was revolutionary at its inception. It offered more flexibility in its capabilities to access multiple sites and could be reconfigured as needed. However, as technology has progressed, so too has our capability of better and more secure solutions.
To use the system, the operator should insert their smart card into the reader on the laptop. This should unlock the laptop. I want the application server to have client-side certificates which somehow are stored (or activated) using the smart card.
May 6, 2024 · Key card access systems are a common type of access control solution that uses different access cards to grant or restrict access to buildings or specific areas. Card readers typically scan these access cards, sending the information to access control panels for verification.
May 31, 2023 · How Do Keycards Work? As the keycard reader accepts the authorized access credential, it quickly signals the specified door or entryway to unlock. Managed by internal software, keycards can also control, restrict, and monitor hallways, elevators, stairwells, and other specialized areas.

Oct 30, 2023 · Proximity card readers work by carrying power and data between the access control system panel and the reader. The reader emits an electromagnetic field so when a proximity card is brought within the field the card is able to transmit its number to the reader through electronic circuits.
