What is RFID/ NFC?

RFID

RFID (Radio Frequency Identification) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder (a device that emits a signal in response to a signal that it has received, also referred to as the “tag”), a radio receiver, and a transmitter( a device that produces radio waves with an antenna).

When triggered by an electromagnetic interrogation pulse from a nearby RFID reader, the tag transmits digital data back to the reader. This data can be whatever information the user wishes to insert on the tag.

Usually, this information comes in the form of inventory tracking numbers for products, identification of individuals in the form of access cards or tags, tracking of products during logistics, identification of animals in the form of RFID chips and many more uses.

There are two different RFID tags possible. Either they are active, meaning they have their own power source or they are passive. Passive tags do not have their own power source and have to be supplied with energy via an electromagnetic field produced by the reader.

Passive transponders or tags are available in three different RFID frequency ranges: Low frequency (LF), high frequency (HF) and ultra high frequency (UHF). The reading range of LF and HF systems is usually only a few centimeters. UHF tags, however, are often readable over distances of more than one meter.

NFC

NFC (Near-Field Communication) is also based on the RFID protocols. The main difference to RFID is that a NFC device can act not only as a reader, but also as a tag (card emulation mode). In peer-to-peer mode, it is also possible to transfer information between two NFC devices.

NFC systems operate on the same frequency as HF RFID (13.56 MHz) systems. Therefore, there are only short read range limitations.

Because of the short read range limitations, NFC devices have to be in very close proximity - usually no more than a few centimeters. That's why NFC is often used for secure communications, especially for access controls or in the consumer sector for contactless payment.

What is the difference between the 13.56MHz and the 125kHz frequencies?

125kHz

When a 125kHz card comes within range of a reader, the card immediately begins to transmit its card number. The data transmitted by the card is not encrypted and is always the same. Data transfer is only one way.

Apart from the low cost, the only real advantage of 125kHz is that due to the lower power requirements and small amount of data being transmitted, it offers a good read range (of about 10cm) and a short read time. This allows users to present, swipe or wave their card in the general direction of the reader to get a successful read.

This is usually used for access control.

13.56MHz

The MIFARE standard 13.56MHz was originally created as a ticketing solution for transport systems, while also addressing the security issues with the 125kHz technology by enabling two way communication between the card and the reader. This also saw the introduction of card encryption and the ability to store data on the card.

When the card approaches the RF field of the reader, the card and reader begin a secure communication session using shared encryption keys. Once this is established, the card number is transmitted and the communication session is closed off. This process happens very quickly, however it does take slightly longer than a 125kHz based system and means that generally, a MIFARE card cannot be simply swiped or waved at a card reader, but must be presented. Also, the two way process requires more energy than 125kHz, meaning a slightly reduced read range of around 7cm.
