Comparing Mifare Ultralight EV1 and Mifare Ultralight C: Understanding the Differences in RFID Technology

Ultralight EV1 and Mifare Ultralight C

You may have come across a wide range of options when seeking RFID tags. It is possible to see chips with the name Mifare. This family of chips is quite common because of their good performance and cost-effectiveness. Today, we want to focus more on the two main options, including the Mifare Ultralight EV1 and Mifare Ultralight C. You might get these two in the market, but they differ in many ways. Learn more about them below.

Mifare Ultralight EV1

Mifare Ultralight is a top consideration among the Mifare Ultralight chips in the market. It was developed by NXP Semiconductors and stands out for its advancement in the use of RFID technology. It is one of the chips that led to wide adoption of the contactless smart card technology. People love it simply because of its ease of integration, multiple use cases, and cost-effectiveness.

The EV1 can be described as the foundation of the original Mifare Ultralight Technology. Even though it still offers key improvements and features compared to other chips in its class. Here are some of its features and specifications.

Memory capacity

The EV1 has a substantial memory of 128 bytes, which is good enough for an RFID tag. The memory is easily programmable, making it suitable for multiple uses. This memory is also organized into multiple pages for flexible data storage and management.

Security features

The Mifare Ultralight EV1 chip is less security-focused than some high-end RFID technologies. However, it offers certain security features that make the RFID tag good for various applications.

The common security features include password protection for the data stored on the chip and individual memory pages. Because of this, such are good for areas that need basic security features.

Application cases

The good thing about the EV1 chip is how it finds applications in a wide range of industries. The most common is access control. The system allows only authorized users to access a building or any other space.

Another use is transportation. It is common to see it being used for ticketing applications in public transportation. This is to make the whole process efficient and fast.

Event ticketing is also available with this type of technology. This means you end up with a quick and secure entry to different types of events.


  • Cost-effective, thus making it ideal for small or large-scale deployments
  • Ease of integration into already existing systems
  • Highly versatile to work with different applications
  • Offers great efficiency with contactless operations


  • Has limited data protection
  • Tends to have memory constraints
  • Security features are basic for some application

Mifare Ultralight C

Mifare Ultralight C is another top product designed and developed by NXP Semiconductors. This RFID chip offers better security features and enhanced data storage capabilities. As such, it is a nice balance between its price and the features it offers.

The Ultralight C is a nice upgrade to the Mifare Ultralight chips. This means more performance and memory capacity while keeping the price. Below are more of its features.

Memory capacity

The memory is bigger than what you get with the EV1. In this case, you get 192 bytes as the data storage capacity. More data storage means handling more applications that need to store more information on the card or tag.

Security features

These are among the standout features of this chip. They make it so easy for someone to find a use for them.

The notable security features include encryption, UID, and password protection. We have 3DES encryption integrated into this chip. This means that the data stored on it is heavily encrypted.

Still, the chip has a unique 7-byte identifier for enhancing the overall card or tag security. This prevents unauthorized duplication or cloning.

Of course, password protection also makes this one even better. This allows you to lock specific memory pages. They will always require authentication for access.

Application areas

As expected, Mifare Ultralight C would have more applications. The most common is access control, but with more security measures. If you have a lab that needs proper security, this is a nice choice to keep unauthorized users out.

It is also a good pick for cashless payments. That is good, especially when hosting events that need many people to be processed simultaneously. Such include sports events, music concerts, and more.

You could also use the same for identification and authentication. If you need the employees or students to be identified before going through the gate, this is a good choice, as few people can clone it and access the premises.


  • Get enhanced security features
  • Offers extended memory
  • Comes with wide compatibility
  • Offers great convenience


  • Costs more
  • It may need additional configuration

Key Differences Between Mifare Ultralight EV1 and Ultralight C

Key Differences Between Mifare Ultralight EV1 and Ultralight C

There are a couple of differences that we have already mentioned above about these two RFID technologies. We will quickly compare the two so that you can know which one is for you.

The first difference is the memory. You get more memory with the Ultralight C chip. This makes it suitable for a wide range of uses. Both models have memories organized into pages for flexible data storage and proper management.

Next are the security features. While the EV1 offers basic security features, the Ultralight C model has advanced security measures. This means that the areas for applications differ a lot. Expect the Ultralight C model to have more applications since it can be tailored to areas that need more security.

Compatibility is not bad for either model. A good example is compatibility with NFC technology. Both models offer seamless integration with NFC devices, which can enhance their uses in various settings.

As expected, the Ultralight C chip is more expensive than the EV1 models. This is because of the new technology going into it to make it better. Because of this, you get that those with budget constraints should have no problem choosing the EV1 chip. If you have the money for it, consider the Ultralight C model.


We live in a world where the needs are different from one person to another. Because of such, it can be good to know that these two options exist. If you ever want to use basic RFID tags that are still good for access control, the EV1 chips will do it. For those who want more security and memory, then the Ultralight C model will be your best pick. Assess your needs carefully, and you should be able to choose the right product.
