RFID is a tracking system device. that uses radiofrequency to identify, track, and communicate with human beings.


Radio Frequency Identification (RFID) is a wireless device system. which contains two-component tags and a reader. The reader has an antenna that emits radio waves and receives signals back from the RFID tag. RFID is a tracking system device. that uses radiofrequency to identify, track, and communicate with human beings.

Advantages of RFID:
Track assets and manage inventory.
Saving time and money through automation.
Improve data accuracy and availability.
Enhancing health and safety.
Better control of production.
Enhance quality and traceability.
Grow revenues.


A smart card is a device that includes an embedded integrated circuit that can be either a secure microcontroller or equivalent intelligence with internal memory or a memory chip alone. The card connects to a reader with direct physical contact or with a remote contactless radio frequency interface.

There are two general categories of smart cards: contact and contactless. A contact smart card must be inserted into a smart card reader with a direct connection to a conductive contact plate on the surface of the card (typically gold plated). Transmission of commands, data, and card status takes place over these physical contact points.

A contactless card requires only close proximity to a reader. Both the reader and the card have antennae, and the two communicate using radio frequencies (RF) over this contactless link. Most contactless cards also derive power for the internal chip from this electromagnetic signal. The range is typically one-half to three inches for non-battery-powered cards, ideal for applications such as building entry and payment that require a very fast card interface.

Two additional categories of cards are dual-interface cards and hybrid cards. A hybrid card has two chips, one with a contact interface and one with a contactless interface. The two chips are not interconnected. A dual-interface card has a single chip with both contact and contactless interfaces. With dual-interface cards, it is possible to access the same chip using either a contact or contactless interface with a very high level of security.
