Essay on Benefits of RFID in Supply Chain Management

An RFID reader is a network connected device (fixed or mobile) with an antenna that sends power as well as commands to the tags. The RFID reader acts like an access point for RFID tagged items so that the tags' data can be made available to business applications.

track the target once it is attached on an RFID tag. Passive tags are used to attach on the target object because they are much cheaper, long lived, lightweight and have a smaller foot print. The reader can communicated with host computer through RS232.

First and foremost the RFID IC or (Radio Frequency Identification Chip) is a tag, label, or card that can exchange data with the reader using its built in antenna and its IC (Integrated circuit ). There are a numerous amount of different things that helps tie this chip tie together, such as your personal ID, Medical history , bank information, and all of the other information government wants to know about you. The chip is inserted by doctors in one of your hands right between your index finger and you thumb they say it take no longer than thirty seconds to a minute.

There are two major hardware components that help RFID to work: Tag and Reader. The two devices have an asymmetric relationship in that the tag is simple and offers few facilities besides holding and transmitting the code, while the reader takes the leading role at the cost of higher complexity. RFID tags store information about the item they are attached to. Information generally pertains to identification information; supply-chain information such as attributes, source, destination, and route; and possibly other special parameters. In business model, RFID tags provide the capability for seamless and continuous two ways communication as an object moves through a supply chain. This means that any object bearing a tag can become networked without human intervention or manipulation by automated machines, as is the case with bar codes. Most of the time, the tag is placed on

The RFID technology consists of three key elements: RFID tags, RFID readers, and a back-end database server to identify information. The RFID tag stores its particular ID and some application data for RFID readers thus the tag contains electronically stored information which is used for access control system. The major advantage of using the RFID tag is that it allows convenience contactless access. However, the traditional RFID-based access control system identifies an individual only by means of his or her RFID card that is anyone who presents a registered RFID card will pass the authentication even he/she is not the genuine card holder or owner. Moreover, there are many RFID attacks which are:

It's grouped under the category of automatic identification technologies. RFID is also called Dedicated Short Range Communication (DSRC). A RFID framework basically comprises of three parts: the RFID tag itself, the RFID reader device, and a backend IT framework. The RFID label ordinarily comprises of a silicon chip that can hold a certain amount of information, (for example, unique identification number), and an antenna wire that is used to communicate with the remote reader device. There are chipless RFID tags too, which misuse certain RF-reflecting properties of materials. In case of chipless RFID, the tags’s unique serial number is given by the material's properties, e.g. the design of RF filaments implanted in paper. The reader device communicates with the RFID tag by method for sending and accepting radio-frequency waves. The way this communication happens contrasts between passive and active RFID tags. Passive RFID tags does not have a power supply; the energy stored in the reader device's radio-frequency interrogation scan is enough to wake up the RFID tag and to enable it to send a response (that is, the RFID tag's data) to the reader device by means of reflection. Active tags contain a battery that permits them to react to the reader’s interrogation with a stronger signal, in this way increasing the distance from which the tag can be read. The backend IT framework is in charge of cross-referencing the RFID tag’s ID number with a database record that describes the object to which the tag is

The data from RFID chip is stored as blockchain. Blockchain technology is in highlights due to its exclusive feature of decentralization and security. Blockchain is managed as blocks where each block contains the checksum of previous block, thus forming a chain, hence called as “blockchain”. These chains are distributed then in the network which ensures the biggest benefit of no centralization to control data. The chains follow proper order and the hash after encryption of previous block is stored with the current block. This continues for all the blocks in chain.The security provided is such that data is tamperproof and fail-proof due to its encryption technique. A blockchain is a decentralized and distributed digital ledger that records transactions across many

Today, the passive tags are the simplest form of tags without any power source such as a battery, in order to start communication with the reader. The passive tag gets its power from the radio waves transmitted by the reader. The tag contains minimal information such as the unique tag ID and it can be read at a range of ten to twenty feet away from the reader. Passive tags are cheaper to manufacture and are mostly used in disposable items or they can also be used in asset management.

The warehouse manages hundreds of products each day and most of the tasks are handled manually. The amount of time required to manually count the products and re-checking the content of the products is enormous, which results in inefficiency hence high cost. Moreover, the extensive involvement of manual labor results in a higher chance of human errors such as inaccurate count and product checking before loading. Given that Zalora Singapore is expecting a rapid growth, it is necessary to come up with a more efficient system and better accuracy for a better customer service.

Based on Word Info, n, RFID means is a technology which automatically detects digital data that has been encoded in an RFID tag which is also known as "smart label". The RFID system is detected via radio waves. MHP Enterprise using the RFID system at the time of delivery of Masri products at supermarkets Giant in Kuala Selangor. The main purpose is the use of RFID systems to ensure products arrive at their destinations, such as the time of delivery at the supermarket. There are two types of RFID systems such as passive and active systems. Refers to passive systems, RFID will work when the RFID transmitting energy field to facilitate this tag operating system. Whereas, also active RFID system will work when the battery is inserted inside the tag to increase the distance to be detected by the RFID system. Typically, the passive system will collect data or information about the product through communication tools such as a wireless or wired. For data storage and provides the action, the bar code will be arrested and then be delivered to a computer

This antenna enables the chip to transfer the waves back to the reader. The reader then converts the radio waves into digital information that can be analyzed from the computer. Based on the frequency the tags are classified as active and passive. Passive tags operate at microwave frequency and its use can be limited in the read zone. It will become latent after leaving the read zone. Active tags have power from an internal battery and hence do not need a reader. These tags can store more data and are expensive than passive tags. The picture below (Fig 1.) describes the process of RFID tags works.

When all is said in done, RFID (Radio Frequency Identification) is a strategy for perceiving a human or item using a radio frequency transmission. The technology can be used to perceive, track, sort or recognize a wide variety of articles. RFID (Radio Frequency Identification) can be portrayed as takes after Automatic ID technology which uses radio-frequency electromagnetic fields to recognize items

Radio Frequency Identification, commonly known as RFID, is a data collection technology that utilizes electronic tags to store data. The tag has many different names such as electronic label, transponder, or code plate. The RIFD chip is attached to an antenna transmitted in kilohertz, megahertz, and gigahertz range. These RIFD tags are similar to barcodes and are used to track items (RFID, n.d.).

In 1960s, RFID began to advance which led companies to use the technology for anti-theft purposes. Electronic article surveillance tags uses radio waves to find out whether a customer had paid for the item. When someone tries to walk out with an item that wasn’t paid for, it gets detected by the reader at the door resulting an alarm. In 1973, the first US patent was issued for an active RFID tag. A RFID tag is saved with a unique numbers which gets broadcasted by a card with the transponder. Therefore, the door would unlock when the reader detects the unique number from the RFID tag. This technology was licensed to different companies, mainly door lock makers. The US government started using RFID to track nuclear materials in the 1970s. The department of Agriculture expands the passive RFID technology to mark cows. The cows were fed with various kinds of medicines and hormones and it is so hard to track how many doses each cow received. A passive RFID solved the problem of cows not getting overdosed through the use UHF radio waves. After, smaller transponders were created that could be injected under a cow’s skin. They still use this technology in cows now days. These low frequency transponder is also used in readers for building access. Later, the commercializing of high frequency enabled companies to have faster data transfer and more range. “Today, 13.56 MHz RFID systems are used for access control, payment systems (Mobile Speedpass) and

Radio Frequency Identification (RFID) uses Radio Frequency electromagnetic energy that can be transmitted and can be used to read the
