In this blog, we’ll break down the basics and answer the questions you need to master MIFARE cards.
What is a MIFARE card?
A MIFARE card (from Mikron FARE Collection System) is a compact plastic RFID card. It contains an embedded chip that can interact with a MIFARE reader. This technology revolutionized contactless card technology in 1994. It was initially made for transport passes. However, later on, it became the leading choice for data storage.
Under the MIFARE family, there are various smart card technologies:
- MIFARE Classic
- MIFARE DESFire
- MIFARE Ultralight
- MIFARE Plus
These cards are manufactured by NXP Semiconductors, a part of Philips Electronics. They operate at 13.56MHz. Furthermore, all of these adhere to the ISO14443A industry standard.
Like other contactless cards, they contain an internal antenna and chip. These parts respond when near the magnetic field of a reader. For a successful transaction, you need to bring the ID card close to its reader.
For instance, you can use them to make payments for transportation fares on a bus or train. Employees also use MIFARE cards to gain entry to a workplace securely.
Aside from these common applications, MIFARE’s practical features have found uses in a wide range of industries as well.
MIFARE cards are your go-to choice for applications requiring high-level security.
They have enhanced security encryption which prevents unauthorized access to card data.
