Long checkout lines at the grocery store are a big turn off when shopping. Soon, these lines could vanish when the ubiquitous Universal Product Code (UPC) bar code is replaced by smart labels, also named radio frequency identification (RFID)readers largely found in Dubai. RFID tags are highly intelligent bar codes that can communicate to a configured and networked system to analyze every product that you add to your shopping cart.
The potential of RFID READERS
Just imagine going to the grocery store, piling up your cart and walking right out the door. No longer will you have to stand and wait as someone at the desk picks up each item in your cart one at a time and note it. The long-range UHF RFID readers in Dubai will exchange rapid messages with an electronic reader that will track every item in the cart and notify each up almost instantaneously. The reader will get connected to a large network that will disseminate information on your items to the retailer and product manufacturers. Your bank will then be alerted, and set amount of the bill will be deducted from your account. No queues, no waiting.
RFID readers in UAE, a technology once zoned to tracking cattle, are tracking consumer items worldwide. Many industrialists use the RFID card access control systems tags to find the location of each item they build from the time it’s created until it’s chosen from the shelf and dropped in a shopping cart.
Outside the area of retail merchandise, long-range RFID readers in Dubai are used to track vehicles, airline passengers, Alzheimer’s patients, and pets. Any time soon, they may even dig out your preference for crunchy or creamy avocado butter. Some critics point out that RFID technology is becoming too much a part of our lives.
In this article, you’ll learn about the classifications of RFID readers and how these tags can be analysed through the entire supply chain. We’ll also have a look at the non-commercial uses of RFID tags.
Reinventing the Bar Code
Bar codes like this one are found on almost every product we purchase.
Almost all that you buy from retailers will have a UPC bar code printed on it. These bar codes help industrialists, and small retailers keep track of inventory. They also send info about the number of items being bought and, to an extent, the consumers who have bought them. These codes act as product fingerprints made of machine-decodable parallel markings that store binary code.
Deployed in the early 1970s to speed up the analysis process, bar codes had a few demerits:
In order to keep pace with inventories, companies must scan each bar code on each box of a single item.
Going through the queue has the same process of scanning the bar code on each item.
Bar code is a read-only technology, which means that it cannot generate any valuable info.
RFID tags are an advancement over bar codes because the tags have both read and write abilities. Data stored on RFID tags can be revised, improvised, and safeguarded. Some stores that have started using RFID tags have analyzed that the technology provides the best way to track products for stocking and marketing departments. Through RFID tags, stores can visualize for themselves how fastly the items leave the shelves and which consumers bought them too.
RFID tags cant entirely discard bar codes in the near future –excessively many retail outlets still use UPC scanners in millions of transactions every year. But as time slips by, we’ll surely see more items tagged with RFIDs and enhanced focus on seamless wireless transactions. The world is already inclining towards using RFID technology in payments through special credit cards and smartphones.
Moreover to retail merchandise, RFID tags have also been involved in transportation devices like highway toll passcards and subway passes. Because of their capability to store data so effectively, RFID tags can calculate the cost of tolls and deduct the fare electronically from the amount of cash that the user pays on the card. Which is way far better than waiting to pay a toll at a tollbooth or piling out coins at a token counter.
But would you enter your medical history to an RFID tag? How about your home address or your child’s safety? Let’s look at two types of RFID tags and how they store and transmit data.
RFID Tags Past and Present
RFID tags like these used to be made only for tracking luggage and large parcels.
RFID technology has been here since 1970, but until nearby, it has been too costlier to use on a large scale. Originally, RFID tags were used to track large products, like cows, railroad cars, and airline luggage, that were cargoes over long distances. These native tags, called inductively coupled RFID tags, were difficult systems of metal coils, antennae, and glass.
Inductively coupled RFID tags were ignited by a magnetic field produced by the RFID reader. Electrical current has an electrical vector and a magnetic vector — it is electromagnetic. Because of this, you can generate a magnetic field with electricity, and you can generate electrical current with a magnetic field. The term “inductively coupled” comes from this procedure — the magnetic field induces a current in the wire.
Capacitively coupled tags were produced next in an attempt to bring down the technology’s cost. These were permitted to be disposable tags that could be applied to less expensive merchandise and made as obvious as bar codes. Capacitively coupled tags employed conductive carbon ink replacing metal coils to transmit data. The ink was printed on paper labels and scanned by readers. Motorola’s BiStatix RFID tags were the front runners in this technology.
Newer innovations in the RFID industry include active, semi-active, and passive RFID tags.
At an elementary level, each tag works in the same way:
Data stored in an RFID tag’s microchip waits to be read.
The tag’s antenna gets electromagnetic energy from an RFID reader’s antenna.
Employing power from its internal battery or power retrieved from the reader’s electromagnetic field, the tag sends radio waves back to the reader.
The reader chooses the tag’s radio waves and interprets the frequencies as meaningful data.
Inductively coupled and capacitively coupled RFID tags aren’t used as commonly today because they are expensive and bulky. Instead, we use active, semi-passive, and passive RFID tags.
Screen Check is the best RFID reader company in Dubai and is equally the best RFID reader distributor too out of all RFID companies in Dubai and RFID companies in UAE.
“Reinventing the barcode with RFID Reader”
RFID Solutions in Dubai are having a booming outspread of employability in recent times. Changes are inevitably visible, and the technology is having a steady pace edge and leaving its presence felt in the highly competitive consumer markets like UAE.
