Comparing IC and RFID Cards: What You Need to Know

how do rfid card work

IC cards and RFID cards are both used for a variety of purposes, such as access control, credit card authorization, and data storage. But while they may seem similar on the surface, there are many differences between the two types of cards that make them suited for different applications. Let’s take a look at how the two types of cards differ from one another.

What Is an IC Card?

An integrated circuit (IC) card is a type of smart card with an embedded microprocessor and memory. It looks like a regular credit card or identification card but contains an encrypted chip that can be programmed to store information, authenticate users, encrypt data, and perform various other functions. An IC card usually requires a PIN or password in order to be accessed.

What Is an RFID Card?

RFID stands for radio-frequency identification. An RFID card is also known as a contactless smart card because it doesn’t need to be inserted into any device in order to work – instead, it uses radio waves to communicate with readers or other devices. The contactless nature of RFID cards makes them ideal for access control applications since they can be used quickly without having to manually enter any information.

Differences Between IC And RFID Cards

The most obvious difference between IC cards and RFID cards is their size; an IC card is typically larger than an RFID card due to its embedded chip technology. Another key difference is that while an IC card requires direct contact with a device in order to work, an RFID does not – it simply needs to be within range of the reader in order for it to work properly. Additionally, while both types of cards are secure, an IC card offers more security features than an RFID due to its encryption capabilities and ability to store more complex data such as biometric information. Finally, IC cards are typically more expensive than RFID cards due to their additional features.


To sum up, both IC and RFID cards have their own pros and cons when it comes to security and cost-effectiveness; which one you choose depends entirely on your specific application requirements. For example, if you need added security or want your system users to have access control without having direct contact with the device they’re using then an IC card would be the better choice; however if you’re looking for something that’s fast and easy then you might opt for an RFID solution instead. In either case, it’s important that you consider all the factors before making your final decision so that you can ensure your system meets your needs effectively and efficiently!
