We all have the experience to visit shopping mall and supermarket to purchase various types of goods. This is the most popular way to buy essential products like cloths, household and groceries etc. Why not ? Because it’s bring us the all necessary items at. Ace where we can choose from. But In this vast of facilities we feel so bored while the cashier scan the barcode or QR code one by one to calculate the grand total. As per marketing theory the babies are looking for chocolate and snacks in this scanning time and add extra expenses on third cash memo. This the time most of the customer doesn’t want to spend for nothing.
How it would be if all the goods are calculated at a time without spending any more time? Yeah!! that’s possible with RFID (Radio frequency identification) technology.
What’s RFID & how it works?
Radio frequency identification (RFID) is a technology where the smart label or RFID tags store the digital data enclosed it and can be read via radio wave. It’s detect the goods from any dimensions without place the code like barcode or QR code.
RFID belongs to a group of technologies referred to as Automatic Identification and Data Capture (AIDC). AIDC methods automatically identify objects, collect data about them, and enter the data directly into computer systems with little or no human intervention. RFID methods utilize radio waves to accomplish this.
At a simple level, RFID systems consist of three components: an RFID tag or smart label, an RFID reader, and an antenna.
RFID tags contain an integrated circuit and an antenna, which are used to transmit data to the RFID reader (also called an interrogator).
The reader then converts the radio waves to a more usable form of data. Information collected from the tags is then transferred through a communications interface to a host computer system where the data can be stored in a database and analyzed later.
Before diving deep into the working of RFID, let’s explore the different components that it comprises.
The major part that RFID consists of are:
1. RFID tag
2. RFID reader
Describe about RFID Tag
An RFID tag consists of an embedded transmitter and a receiver. RFID component comprises two parts:
1. Integrated circuit: It’s used for storing and processing the information.
2. Antenna: It’s used to transmit and receive signals.
RFID tags also have non-volatile memory storage, which includes either programmable or fixed logic for sensor data and transmission.
Tags can becategorized as:
1. Passive: This tag remains dormant since it has no battery. It uses the reader’s signal energy to turn on the tag along with reflecting a signal back to the reader that carries the information.
2. Active: Active RFID tags have a battery in it that transmits signals periodically. These tags have a range of up to 100 meters due to the presence of a battery. Due to this, active tags are useful in location tracking applications.
3. Battery-assisted passive: These tags do contain a battery, but it doesn’t transmit signals periodically like that of active RFID tags.
The battery is used to turn the tag when it receives a signal, which enables all the energy from the reader’s signal to reflect
Application of RFID
This is very advanced technology that can be used in various industries to track down easily any goods or item. Here are a discussed about a few industry for and it’s advantage.
Agriculture
· Livestock tracking
· Exact food for exact animal
· Routine health check-up
· Measuring annual growth
Garment industry
· Production management
· Shipment chain
· Warehouse store
· Retail business
· Guarantee and warranty validation
Library system
· Amount of books contain in the liberty
· Track the lost book in the library building
· Book rent ledger
Jewelry track
· Amount of jewelry and it’s marker value.
· Find specific design on shelf
· Their protection
· Easy to find customers price range at a time.
Supply chain management
· Find out the manufacturer and it’s receiver destination
· The desired good is correct or wrong?
· The goods correct warehouse before shipment.
· The correct ship for shipment.
