9 best key cards

Key cards, often referred to as access cards or proximity cards, are commonly used in office environments and other secured locations for various purposes related to access control and security. Here's what you need to know about key cards:

Access Control: Key cards serve as a secure means of granting access to specific areas or resources within a building or facility. They are used to control who can enter or exit certain spaces, enhancing security and ensuring that only authorized individuals can access restricted areas.
Types of Key Cards: There are different types of key cards, including magnetic stripe cards, RFID (Radio-Frequency Identification) cards, and smart cards. Each type has its own technology and level of security.
Magnetic Stripe Cards: These key cards have a magnetic stripe on the back that stores information. When swiped through a card reader, the information on the stripe is read and verified for access. Magnetic stripe cards are commonly used for simple access control systems.
RFID Cards: RFID key cards use radio waves to communicate with a card reader. They are more secure than magnetic stripe cards as they are harder to duplicate or tamper with. RFID technology is commonly used in office buildings, hotels, and parking garages.
Smart Cards: Smart key cards have an embedded microchip that stores and processes data. They can provide a higher level of security and functionality, such as storing biometric data or enabling multi-factor authentication.
Applications: Key cards are used in various applications, including granting access to office buildings, secure rooms, parking garages, hotels, and educational institutions. They are also used for time and attendance tracking in some organizations, where employees clock in and out using their key cards.
Programming and Management: Key cards are typically programmed and managed by an access control system. Authorized personnel can add or revoke access privileges for individual key cards, making it easy to manage security.
Lost or Stolen Cards: In the event of a lost or stolen key card, it is important to deactivate or reissue the card to prevent unauthorized access.This is a crucial security measure.
Customization: Key cards can be customized with employee or user information, logos, and other branding elements. This helps identify cardholders and adds a layer of professionalism to access control systems.
Security Protocols: To ensure the security of key card systems, it's essential to have robust security protocols in place, such as encryption, secure storage of card data, and regular system audits.

Key cards are an integral part of modern access control and security systems, providing convenience and security for businesses and organizations. They play a vital role in safeguarding physical assets, sensitive information, and ensuring the safety of personnel and visitors.

User questions & answers

Question:	this works with onity ht
Answer:	In general, the cup size increases a cup size with each additional band size, so that the volume of the cup of a 34D is basically the same as a 36C or a 38B.
Question:	How thick is the card? Is it a better quality, as we use Ilco locks and the cards seem to stop working after a few uses
Answer:	There are mat hangers for this purpose.
Question:	are these compatible with Saflok key coder
Answer:	Always check your mat and make sure it fits a 5x7 insert ,the outer mat could measure 11x14.
Question:	Can you order this item with the Best Western Logo
Answer:	The inside opening is 8 x 10, the outside measurement is 11 x 14, a picture frame size that is easy to find, even in Big Box stores. The quality of this set is quite good. You get the bevel cut mat, backboard, and a plastic sleeve to protect your framed project for storage, gifting, or protection until you purchase the actual frame. I had purchased a set of four prints, and used this item to put together a nice presentation, figuring the person who received it would buy the frames. I am considering buying a few more sets due to the quality, ease of use, and price.

User questions & answers

Question:	is this compatible with ilco
Answer:	there are 2 different bottles one is Black Obsidian Crystal and the second one is Clear Quartz Crystal.
Question:	do you have a list of door lock system your cards work with
Answer:	The standard shipping in the US is 3-7 business days.
Question:	Are these keys compatible with Onity Tesa door locks
Answer:	When I ordered this item, I was given choice of color.
Question:	are these compatible with Kaba locks
Answer:	There is a soft lining in the cup - I've had no problem with it and I'm a 44DD - I actually could go down a size - this bra is very roomy but comfortable - I've been wearing Bali for some time and they always tend to be small around (circumference) - more so than anyone else I've tried. I think if your used to a normal 42 (not Bali) you will be fine at 42. Having said that, I do prefer the Bali cup shape - this one though, does a very good job of minimizing. Every body is somewhat different, I guess. Hope this helps, Peggy. . . . . . .mj

Answer:	Hello Alex. It depends on what access control system you have. Every system has a different method of enrolling cards. You don't necessarily need an enrollment reader. Most our customers don't have one of those. You just need the facility code (100) and badge number (5 digits) that are printed on the badge. Let me know if we can help you get the cards set up in your system. I have about 15 years of access control installation experience and would love to help. Thanks Alex.
Question:	Does this item cove with the card holder, tassel, and big ring
