RFID chip
What exactly is RFID? RFID is an abbreviation of: Radio Frequency Identification and stands for a very versatile technology based on radio waves. You can program certain data on an RFID chip, which can be scanned up to a distance of up to 8 meters. So think of an RFID chip as a kind of smart sticker that is incorporated into a plastic card. In addition to plastic cards, we can also supply RFID tags such as drops (keyfobs) and wristbands.
The different RFID technologies
At Cards Unlimited we use different technologies for an RFID card:
NFC TECHNOLOGY
NFC stands for Near Field Communication. As the name suggests, it involves wireless communication over a short distance. An NFC chip can be scanned from a distance of up to 10 centimeters. We see applications of an NFC chip, for example, in access controls, contactless payments or price tags.
MIFARE TECHNOLOGY
MIFARE is a type of RFID chip. There are different types of MIFARE RFID chips. The difference between them is in the available storage space, range, frequency and security level.
Types of MIFARE chips
There are various MIFARE cards on the market. Below we list the three most famous ones:
MIFARE Classic
MIFARE Ultralight
The MIFARE Ultralight is often used as a disposable card. The card has a memory of 64 bytes and is not equipped with security. Ideal for an application such as one-time access to an event.
MIFARE DESFire
The DESFire has more hardware and software security than the Classic. Available with a memory of 2.4 or 8 kilobytes. The DESFire is a popular MIFARE card for access controls.

MIFARE applications
The applications of RFID cards
You probably already use RFID on a daily basis: from a public transport chip card to access to your office building. There are various applications of RFID:
Access control with an RFID chip
RFID technology is a popular choice for access controls. In this case, the carrier is a plastic card, key ring or key fob. Consider, for example, access to a hotel room, office building or gym, but also a locker or event. The following features make RFID suitable for access control:
- The transfer speed of RFID cards is high, the data is read within a few seconds.
- Short (NFC) and long reading distance (MIFARE) techniques are available.
- RFID chips are often enclosed in a card or other carrier. This protects the chip against external influences, such as water and dirt.
- RFID is difficult to imitate and therefore provides a greater level of security than, for example, a barcode.
Paying with RFID
RFID and NFC also play a role in payments. For example, consider contactless payment with a debit card or smartphone, which works using NFC technology. Bank cards or credit cards are often provided with an RFID tag.
