RFID chips are the primary components of electronic tags. It's also worth noting that RFID chips are at the heart of the entire RFID system. The primary structure of the tag chip consists of a radio frequency front end, an analog front end, a memory unit, and a baseband (digital).
RFID chip frequency bands include 2.45 GHz, 860-960 MHz, 433 MHz, 13.56 MHz, and 125 kHz, among others. The conventional frequency bands are 860-960 MHz (Ultra-high frequency) and 13.56 MHz (low frequency) (High Frequency).
MIFARE is an abbreviation for the Mikron Fare Collection system, and it is a well-known contactless solution from NXP. MIFARE is notable for its versatility, which is why it is used by organizations and corporate bodies.
Have you ever been to an organization where some employees have access cards to private areas? Many of these locations are restricted, and only those with the cards are permitted entry.
It's worth noting that these cards use RFID chips that contain the employee's information or data. The system also includes an RFID reader, which checks the data on the card within a 4-inch range. The employee would be able to enter if the system reads the information as correct and accurate.
If you want the best for your company, an RFID MIFARE chip is the way to go. And this is because there is a lot to be gained by using standard chips.
MIFARE Classic
The first contactless smart ticket Integrate circuit is MIFARE Classic. It operates at a frequency of 13.56 MHz, in accordance with ISO 14443 standards, and has full read/write capability. The MIFARE Classic helped to pioneer the contactless movement by establishing standards for a variety of applications in universities, organizations and corporate bodies, access management, and public transportation.
The MIFARE Classic has either a 7-byte unique identifier or a 4-byte non-unique identifier. The MIFARE IC 1K has one KB divided into sixteen parts, whereas the MIFARE IC 4K has four KB divided into forty parts. It also has memory that can be configured.
MIFARE classic chips are currently among the most dependable and affordable on the market. As a result, more people and organizations have come to rely on it. The disadvantage of this was that as the use of MIFARE classic chips increased, security flaws became apparent.
As a result, NXP developed a more stable system known as the MIFARE Classic EV1, which is ideal for security-related applications.
MIFARE Classic EV1
The MIFARE Classic EV1 is an upgrade to the original classic chip. It has 4K and 1K EEPROM memory options. This is excellent because it ensures flexibility. It is correct to say that the MIFARE Classic EV1 represents the pinnacle of the MIFARE Classic family's metamorphosis.
The MIFARE Classic EV1 has a strong electrostatic discharge, allowing for easy use of the integrated circuit during the card production and inlay process. It also has improved ESD features and an NXP-enabled originality check function, among other things.
The MIFARE Classic EV1 has been used in the public transportation sector for a variety of purposes, including access control and time tracking.
MIFARE DESFire
MIFARE DESFire is a large group that includes the MIFARE DESFire EV1, MIFARE DESFire EV2, and MIFARE DESFire light contactless integrate circuit. The MIFARE DESFire is best suited for system handlers and solution developers who create reliable, consistent, and extensible contactless solutions.
The MIFARE DESFire group is essential in smart car solutions, transportation schemes, and small-scale payment transactions, which is one of the best parts. And, to your surprise, the MIFARE DESFire IC product meets the standards for timely and secure data and information transmission.
Furthermore, the MIFARE DESFire has adjustable memory handling and is compatible with traditional contactless systems. In addition to the four ISO/IEC 14443A levels, the MIFARE DESFire meets global standards for cryptographic and air interface. Surprisingly, the MIFARE DESFire IC products support NFC.
The MIFARE DESFire IC products include three-pass authentication as well as a competent on-chip backup management network. Intriguingly, the MIFARE DESFire smart card can hold up to 28 different applications, with each application containing 32 files. Because the size of each file is fixed at the start, MIFARE DESFire is a suitable and adaptable product group.
Furthermore, the MIFARE DESFire EV2 can support an infinite number of different applications, which are only limited by the memory size of each family member. As a result, once the card is in the market, new applications can be integrated. Furthermore, two or more applications can share a purse for improved compatibility.
Surprisingly, all file types include an automated anti-tear system that ensures smooth and consistent data processing. It may surprise you to learn that MIFARE DESFire ICs can achieve up to 848 Kbit/s, making data processing fast, smooth, and secure.
The MIFARE DESFire is an excellent choice if you are looking for products with improved client-friendly designs that provide reliability and security.
MIFARE Plus (Multi-Factor Authentication)
The MIFARE Plus product group provides Advanced Encryption System security to contactless applications as one of its primary functions. The MIFARE Plus allows for a simple and painless upgrade of MIFARE Classic products and services.
Because of this feature, there is a good chance that issue cards will work well with MIFARE Classic in prevalent system environments prior to security infrastructure upgrades. Following the security upgrade, the MIFARE Plus products run authentication with AES security, as well as other features like encryption and data integrity that are based on global standards.
MIFARE Ultralight
Currently, the MIFARE Ultralight family includes three members who provide system integrators with complete flexibility and proficiency in running complete system solutions. The interesting part is that these features are not limited to zones, times, or single-use or multiple-use tickets.
Because these tickets cannot be reloaded, integrators will benefit greatly from them. As a result, a secure infrastructure is provided to facilitate this feature, with its OTP (One-Time-Programmable) Memory in accordance with the UID (ISO Unique Identifier).
MIFARE Ultralight product tickets are not out of the question; they are ideal for low-cost, high-volume applications such as loyalty cards, public transportation, and event tickets. It may be of interest to you that MIFARE Ultralight product tickets are the ideal contactless replacement for barcodes and magnetic stripes. This explains the trend of converting entire systems to entirely contactless solutions.
MIFARE Ultralight Integrated Circuit solutions have resulted in fewer system installations and lower maintenance costs since their inception. MIFARE Ultralight products are simple to integrate into running schemes, and paper-ticket vending tools can be seamlessly upgraded.
In addition, the MIFARE Ultralight chip family can be used in hotel rooms and other places that require access authorization.
What Is the Distinction Between Them?
When NXP first developed the MIFARE Classic Chip, stringent security measures were not included. As a result, when other families were developed, security was improved when the chips were used for various transactions.
The most recent chips include enhanced security features, password protection, and other cutting-edge data protection features. If you use applications that require advanced security, you must avoid using the MIFARE Classic Version.
