The active RFID tags have their own source of power. They can transmit stronger signals over long distances and can operate in rugged environment for many years. Because of the on-board source of power they are larger in size and expensive. Then too Active RFID and Real-Time Location solutions (RTLS) are saving millions of dollars for enterprises around the world....

RFID vs Barcodes | Difference between RFID and Barcodes

As far back as 1960s, the barcodes were used in industrial work environments. In the early 1970s, common barcodes started appearing on grocery shelves. To automate the process of identifying grocery items, UPC barcodes were placed on products and were used to mechanize the process of checking out in store. They are in use today also for allotment, supply chain, retail stores, apparel shops,...

RFID Interfacing with 8051 Microcontroller (AT89C51) using ...

Himanshu Choudhary

This topic covers the interfacing of RFID system with microcontroller through serial interrupt. An RFID system consists of a reader device and a transponder. A transponder or tag has a unique serial number which is identified by the reader. RFID tag is applied to products, individuals or animals to identify and track them through this number.

The interfacing...

What are the Passive RFID Tags? - EngineersGarage

Written By:

Shurvi Sisodiya

The passive RFID tags do not have any power source and hence they have indistinct operational life span. The power needed for functioning is taken from the reader when the tag comes in the vicinity of the reader. They are available in a variety of sizes ranging from sizes which can fit into adhesive label. The passive RFID is basically made up of three parts: Antenna...

RFID based Security System using 8051 microcontroller ...

The RFID tag is used as an identity for a particular user. If the identity (serial number of the tag) of the user is matched with the one already stored in this system, he gets immediate access through it. This RFID based secured access system also has many additional features. For example, a new user can register himself with the system. A registered user can also withdraw his entry from the system. These features can be accessed by pressing a tactile switch connected to the microcontroller.

In beginning, the user is prompted to scan his tag or ID. The serial code of the tag is identified...

RFID Interfacing with PIC18F4550 Microcontroller : Circuit ...
