Today, we live in an age of wireless revolution where every effort is directed towards getting rid of wires. Removing wires not only makes things easy but also improves speed of operation. For example no one wants to stop at a toll tax and then mechanically deposit money rather there needs to be mechanism through which the car needn’t be stopped and still the tax gets deposited.
This will help in both achieving customer satisfaction as well as improving the efficiency of whole system. Similarly identification of different things has also achieved new heights. It is very important to keep track of one’s assets and hence unique identification has a major scope of development.
This unique identification system will improve the overall efficiency of the system and will bring more social security. Through this technology we can keep track of our pets, clothes, cars and various other things. This technology has application ranging from commercial purposes to even for an individual. In this project there will be a unique id tag for each item. The receiver keeps on receiving the id of items uniquely. If any component is not in the range, then on the LCD the id will not be shown hence we can predict that it is missing. Here we have used rf transmitter with the HT12E encoder IC to make the rf id tag. At the receiver end, HT12D with RF receiver is used to decode the id of the transmitter.
