Recommended: RFID and its role

Abstract: Radio Frequency Identification (RFID) technology uses radio frequency to track or detect objects using tags and readers. This is similar to the barcode detection but barcode detection requires the object to be in the line of sight. Due to the wireless nature of RFID, we find its use in various applications such as in retail management, healthcare, toll stations, postal service and many other areas. However, RFID has various problems and concerns associated with it. This paper focuses on some of the issues seen in retail management. The paper also provides a handful solution to counter some of these issues. After considering some of these solutions, the paper provides us with ideal RFID network that can be use in day-to-day life. Shah-1 1. Introduction: What is RFID? RFID as a technology has grown rapidly over the past few years due to its application in various areas. After its inception, the cost of RFID tags have declined significantly over the past few years, that it is now beginning to replace the barcode system. [12] Unlike barcodes, RFID tags are smart tags with an in-built memory that can contain variety of information about the object. RFID makes use of radio waves to track objects. This automates tracking, reduces human workload and improves management. RFID tracking consists of tags and readers. An RFID tag consists of an integrated circuit that has memory and a transponder that acts a transmitter and receiver to send and receive information to the RFID reader. Tags are of three types: Passive, active and Battery assisted passive tags (BAP). Passive tags operate without battery and are cheapest of all the tags. Active tags have an in-built battery that supplies power to the tag.

    The article then follows with “even low id error rates can lead to serious medical errors” further illustrating the dangers associated with incorrect ID’s. Following the study conducted at The University of Kansas Hospital (2003) shows trends that barcoding of patient’s wrist bands has reduced all errors associated with incorrect ID’s. This technique seems to be improving the system so fewer errors do occur, why in general is more economically viable.

  • Ethical Implications of Placing Implantable Chips in Patients

    1847 Words  | 4 Pages

    The placement of implantable chips into patients for the purpose of accurately identifying patients and properly storing their medical history records has become a subject of a strong debate. Making sure patients are properly identified before a procedure and storing their health history records for future use has been difficult, if not impossible. The idea of being able to retrieve accurate patient’s medical history for a follow up care without relying on patient’s memory is a challenging task for many healthcare organizations. Many ideas and technologies have been introduced over the years to help solve this problem, but unfortunately the problem is still not fully resolved. There are still many errors in the healthcare due in part by improper record keeping and inaccurate patient identification. One idea that has being in discussion to eliminate these problems for good, is the introduction of a chip or radio frequency identification (RFID) technology implanted into human for the purpose storing medical data and accurately identify patients. VeriChip Corporation is currently the maker of this implantable RFID chip. They are the only corporation cleared by the U.S. Food and Drug Administration (FDA) to make this implantable radio frequency transponder system for humans for the purpose of identifying patients and storing their health history information. The chip was first developed for the use of radar systems by Scottish physicist, Sir Robert Alexander Watson-Watt in 1935 just before World War II. (Roberti, 2007). This technology helps identify approaching planes of the enemy from mile away. Today, RFID has several uses. It is used for animal tracking. It is attached to merchandise in stores to prevent theft. It can be instal...

    The innovation of the RFID chip or the Radio Frequency Identification has been a critical piece of technology that has been around since the early/mid 20th century (est 1938). Functions of a radio frequency identification (RFID) tagging system involves a tag and a reader. When scanned, the antenna within the tag picks up the radio wave and sends a response back to the reader.

    The microchip is a tiny transponder the size of a grain of uncooked rice. The chip is a permanent radio-frequency identification (RFID) chip implanted under the dog's skin that can be read by a chip scanner or wand. Implantation is done with an injector that places the chip under the loose skin over the dog's shoulder. This is a quick and easy process that can be done by all veterinarians provided they have the right technology to do so. The chip identification number is stored in a tiny transponder that can be read through the dog's skin by a scanner emitting low-frequency radio waves (Woolf 1). The frequency is picked up by a tiny antenna in the transponder, and the number is retrieved, decoded, and displayed in the scanner readout window. The radio waves use a frequency much lower than AM broadcast stations use, and they must be approved by the Federal Communications Commission before they can be marketed (Woolf 1). The chip, antenna, and capacitor are encased in a tiny glass tube. The tube is composed of soda lime glass, which is known for compatibility with living tissue. The glass is hermetically sealed to keep moisture out.

    Each of these recommendations can in its own way contribute to a better managed supply chain and more control for Target over its inventories. The reduction of stockouts, even if it only results in the recovery of 5% of potential lost sales, vice the expected loss of 7% mentioned earlier, would be an additional $3.6B in added sales on the top line. For this reason, Target must choose and implement at least one of these recommendations. For all practical purposes it is likely that Target will implement more than one of these solutions, but we have assessed that the RFID tag solution is the most aggressive approach and offers the best long-term solution for this problem.

  • RFID vs Barcodes

    938 Words  | 2 Pages

    Radio frequency identification (RFID) is a computerized ID innovation that uses radio recurrence waves to exchange information between an onlooker and things that have RFID gadgets, or tags, joined. The tags hold a microchip and receiving wire, and work at universally distinguished standard frequencies. Barcodes are much smaller, lighter and easier than RFID but RFID offers significant advantages. One major advantage of RFID is that the innovation doesn't oblige any observable pathway the tags could be perused as long as they are inside the range of the spectator, whereas in barcodes in order to read the barcode the barcode scanner should close around 10-15 fts. In RFID data, for example, part and serial numbers, assembling dates and support history is put away on the tags and catches which help in maintenance of equipments.

    What is this world coming to? When most of us think of tracking devices they think of primarily negative issues. But that has all changed now. A tracking device the size of a tic tack that can be surgically implanted to provide a tamper proof means of identification, enhanced e-business security, locating lost or missing individuals, monitoring heart rate, vital signs, tracking of the elderly, the location of valuable property, and monitoring the medical conditions of at risk patients, all at the convenience of a button or a phone call (www.allnet). It is called the GPM or as we know it the Global Positioning Microchip. Today I will discuss the ideals of the implanted microchip and some of the technical, social, economic, ethical and practical implications of its technology. Furthermore exploring some of the benefits and dangers of such a device. Invented entirely for animals man has expanded its uses to stolen cars tracking devices, criminal rehabilitations, and experimental animal observations. The chip has come a long way but where will it go from here.
