With the fast changing technology these days, the way in which we address our very own security needs is also changing. Keeping homes and businesses secure has gotten much easier over the past few decades. In today’s office buildings, factories, schools and homes, physical keys are becoming a thing of the past. Access control systems are now able to operate on a digital level making it much harder for intruders to gain access to certain areas. This new technology allows individuals to gain access without ever sticking a key into a lock.

Access control systems perform authorization identification, authentication, access approval, and accountability of entities through login credentials including passwords, personal identification numbers (PINs), biometric scans, and physical or electronic keys. However, when it comes to choosing a modern access credential solution, there are two main options to choose from: access cards and access key fobs.


The most popular credential of today’s access control systems are “access cards” instead of the standard metal key and lock system to grant access to the secured area. There are different types of access cards and each require a access control card reader to be installed near the door, parking garage, gate or elevator and you gain access by either tapping your card on the access control reader (proximity reader), swiping it (swipe reader), or inserting it (insert reader). If the code on your card is recognized by the reader, permission is granted for access.


Proximity access cards, also known as Prox cards or access control cards, are contactless ID cards containing programming that is “read” by a proximity card reader to control and secure physical access. These cards use a radio frequency (RF) signal sent by the transmitter.

When the prox card is held at a certain distance from the access control card reader, the RF signal is absorbed by a small coil inside the card that powers up the card’s microchip which contains a unique identification code. Once powered, the card will then transmits the code to the reader. The proximity reader usually produces a beep or other sound to indicate the card has been read. The whole process is completed in seconds.



Magnetic stripe card, sometimes called swipe card or magstripe, use a magnetic stripe at the back of the access card to encode data. This magnetic layer is capable of storing data by altering the tiny magnetic particles. The magnetic stripe reader’s head reads the data when you swipe the card through it and enables access. Swipe cards are a convenient and an affordable solution to control access. Magnetic stripe cards are also commonly used in credit cards, identity cards, and transportation tickets.


Smart cards are the most advanced “contactless” cards on the market today. They function like proximity cards, but have the ability to store information – they can read and write data to the card. A smart access card can provide identification, authentication, and store information on the card because of the microchip and memory embedded within the smart card. This makes them significantly more useful than magnetic stripe or proximity (prox) access cards. Because they carry more data than any other access card, they also tend to be more expensive.


An alternative to access card entry system are key fobs, which have the same function but can easily be attached to key rings instead of being stored in a wallet or purse. Key fobs are pocket-sized security tokens with built-in authentication installed in the unit that either grant or deny access to a particular facility or area of the facility. Key fobs are durable and provide a cost-effective access control solution for controlled access of door entry, gates, garages and more. Thanks to their security features, key fobs are becoming more and more popular, not just for personal homes and automobiles, but in the office and commercial environment as well.

Access cards and access key fobs are great access control solution for businesses, schools, factories and other organizations looking to move away from physical keys. Whether you need access control credentials for a few users or several hundred, we have an access control system to meet your specific requirements. Browse our access cards and key fobs online to learn a little more or request a quote to have one of our access control consultant visit you and inform you of all the access options available for your property. Dicsan Technology also offers access control readers for easy and convenient card access control solutions for your facility.


Each type of access control card has its pros and cons. The main idea is to determine what will work best to enhance your security as well as function well in incorporating other applications that your stakeholders identify. Our access control technicians will work with you to understand your property’s needs in designing location and security specifics of your system. We’ll work with you to discuss your options, recommend technology formats and more. If you’re in the market for a new access control system for your home or business, or repair or upgrade your existing system, get in touch with Dicsan Technology today at (786) 622-2221. We’ll be glad to help you find the best product for your needs!



In the fields of physical security, Access control is any mechanism or system that is used to control access into or out of any area through the authorization or revocation of rights to physical or logical assets within a business or home.


Access control card readers are one of the major component of an Access Control System. These are used to read the encrypted data on an access card and allow or deny access based on the card information with the feedback from the control panel.


The standard form of today’s access control is an “access card” instead of the standard metal key and lock system to grant access to the secured area. There are different types of access cards and each require an access control system card reader.


RFID stands for Radio-Frequency IDentification. The RFID device serves the same purpose as a bar code or a magnetic stripe; it provides a unique identifier for that object. RFID is fast, reliable, and can be read from up to several feet away.


Motion sensors are found everywhere today and function by detecting a vehicle or person approaching an exit and unlock the door. Due to their motion sensor they can trigger motion and thus unlock the door right when you walk up to the door to exit the space.


Access controllers are split through many types of control models an features, all of them providing the essential services of authorization, identification and authentication.


Every access control system needs a server where the permissions are stored in an access database. It is really the server which makes the decision if the doors should unlock or not by matching the presented credential to the credentials authorized for this door.


Magnetic locks and electric strikes are electrical hardware devices used to maintain the security of a door opening. Both of these devices can be activated by a range of tools, including passcodes, biometric readers, keycards or buzzers.
