Access Control with Smart Cards

An organization's security strategy should include access control; it protects private areas from unauthorized access and streamlines operations for authorized personnel. Smart cards are credit card-sized plastic pieces that contain RFID or NFC chips, which enable them to store and communicate data with compatible readers and devices. We'll take a look at why smart cards are such an effective access control solution and some key considerations when using them in your organization.

How does a smart card work?

An integrated circuit card (or smart card) is a physical device consisting of embedded microchips with memory and/or processing capabilities. Due to their encrypted storage and data transmission capabilities, these cards provide improved security over traditional magnetic stripe cards by securely storing unique identification numbers and other information about their user.

Different sizes, shapes, and form factors are available, including credit-card sizes used in identification badges, hotel keys, and loyalty programs. At checkout terminals, users can tap their smart card against a wireless reader device to make payments using contactless smart cards.

Further, smart cards can be classified into two distinct types: contactless cards, which exchange data through RFID or NFC technology without requiring physical contact between the card and reader; and contact-based cards, whose chips must be inserted into reader devices or terminals before they can communicate.

Due to their non-contact nature, contactless solutions offer additional advantages (such as faster transaction speeds).

Access control benefits of smart cards

Compared to traditional mechanical keys or even biometric solutions such as fingerprints or facial recognition systems, smart cards offer several advantages as an access control solution, but most notably, they are extremely cost-effective. The lower initial investment costs and reduced maintenance fees associated with updating credentials over time are due to the ability to replace existing credentials on smartcards rather than purchasing new hardware whenever updates are required.

Also, they offer enhanced convenience since they use similar credit/debit payment systems that allow users to pay quickly by tapping their card against designated readers instead of manually entering PINs/passwords.

Last but not least, they provide enhanced security since they feature enhanced encryption and two-factor authentication protocols making it much more difficult for hackers to gain unauthorized access to protected applications/infrastructures with stolen credentials - ensuring that only authorized personnel can access confidential information securely!

Smart Cards: How They Work

Smart cards are RFID cards with embedded microchips that can store large amounts of data. To control access, the chip on the card can be programmed with specific data and authentication methods.

A user's identity and the areas or resources they have access to might be included in this information. Someone enters their PIN code or provides other authentication such as a fingerprint scan in order to gain access to an area or resource.

In order to verify the user's identity and permission to enter or use the resource, the system compares the data stored on the chip with its records. The user will be granted access if everything checks out; otherwise, they will be denied.

Smart card types

Card of identification

ID cards contain personal information such as a name, photo, and possibly other identification numbers. ID cards are used for a variety of purposes, including verifying identity and granting access to secure areas. There are many types of ID cards, including driver's licenses, student IDs, and company badges. To enable various levels of security verification, cards may feature different technologies such as barcodes or RFID chips.

Card IC

Through radio waves or electromagnetic fields, the IC Access Card exchanges information at a frequency of 13.56MHz.

As a result of its contactless convenience and long life, it is used for access control, bus tolls, subway tolls, and other occasions.

It also has high-security features, such as two-way control with computers, which makes it difficult to copy; however, the cost is high.

M1 cards feature encryption logic circuits and programmable read-only memory, but they offer only low-level protection against malicious attacks.

Card for CPU

Computer cards with CPUs contain a single-board computer with an integrated processor and other electronic components. Automation control systems or point-of-sale terminals are typical applications where space is at a premium.

Typically, CPU cards are compact, low-power, and have excellent processing capabilities. It is possible to program them to perform specialized tasks, such as running programs or operating specific hardware.

There are many advantages to implementing smart cards in your organization's access control system, as you can see.For organizations looking to improve their overall security posture, smart cards offer a host of benefits, including enhanced security, reduced administrative costs, and improved efficiency.
