As organizations strive to bolster their access control systems, smart cards are becoming an increasingly popular solution. Smart cards are a secure and cost-effective way to control who has access to sensitive areas or documents. But what exactly are they, and how do they work? Let’s take a look at how smart cards in access control can benefit your organization

What Are Smart Cards?

Smart cards are credit card-sized items that contain integrated circuits embedded with data. They come in various forms, including contactless cards and magnetic stripe cards. These cards store information securely and enable users to authenticate themselves as well as access various services or resources. Smart cards have been around since the 1970s, but with the advent of modern technology, their usage has become much more widespread.

How Do Smart Cards Work?

Smart cards use a form of encryption called public key infrastructure (PKI) to securely store data on the chip inside the card itself. This data can be used for authentication purposes—for example, when you swipe your keycard at the door of a secure facility, the information on your card is compared with that stored in the system’s database and if it matches, you gain entry. This process ensures that only authorized personnel can gain access to sensitive areas or documents. The same process also works for online access; when you log into an account using your smart card, the system compares your credentials with those stored on it before granting you access.

In addition to this authentication process, smart cards can also be used for other functions such as storing medical records, managing loyalty programs, accessing public transportation networks and more. This versatility makes them an ideal solution for many different organizations. However, there are several factors which must be taken into consideration when implementing a smart card system into an existing security infrastructure—including costs, technical requirements and user experience—so it is important to carefully evaluate all options before making any decisions.


All in all, smart cards offer organizations a secure yet cost-effective way to control who has access to sensitive areas or documents within their businesses or institutions. They provide enhanced security through encryption methods such as PKI while also offering increased convenience through their versatile applications across many sectors. System integrators and purchasing personnel should thoroughly research available solutions before making any decisions about implementation – but rest assured that investing in smart card technology is one surefire way of increasing security within your organization today!
