Components of an RFID System

Radio frequency Identification (RFID) as the name implies uses radio frequency to exchange data between two entities for identification purpose. It is a wireless technology to collect information without any human interventions.

An RFID system is basically an integrated combination of various components which work together for detection and identification of objects or persons. These are the components which are primarily responsible for working of any RFID system whether basic or complex. Although there can always be additional components associated with RFID systems like sensors etc. but the following are amongst the key components of these systems:

  1. A tag (sometimes called a transponder), which is composed of a semiconductor chip, an antenna, and sometimes a battery.
  2. An interrogator (sometimes called a reader or a read/write device), which is composed of an antenna, an RF electronics module, and a control electronics module.
  3. A controller (sometimes called a host), which most often takes the form of a PC or a workstation running database and control (often called middleware) software.

The tag and the reader communicate information between one another via radio waves. When a tagged object enters the read zone of a reader, the reader signals the tag to transmit its stored data. Tags can hold many kinds of information about the objects they are attached to, including serial numbers, time stamps, configuration instructions, and much more. Once the reader has received the tag’s data, that information is relayed back to the controller via a standard network interface, such as an Ethernet LAN or even the internet.… Read the rest

Introduction to Radio Frequency Identification (RFID)

In past few recent years, the automatic identification techniques have become quite more than popular and they have also find their places into the core of service industries, manufacturing companies, aviation, clothing, transport systems and much more. And, it’s pretty clear by this point of time that the automated identification technology especially RFID, is highly helpful in providing information regarding the timings, location and even more intense information about people, animals, goods etc. in transit. RFID is responsible for storage of large amount of data and is reprogrammable also as in contrast with its counterpart barcodes automatic identification technology.

In everyday life, the most common form of an electronic data-carrying device if often a smartcard which is probably based upon the contact field. But, this kind of a contact oriented card is normally impractical and less flexible to use. On the contrary, if we think of a contactless card with contactless data transferring capabilities, it would be far more flexible. This communication happens between the data carrying device and its reader. Now, this situation may further appear as ideal if it so happens that the power for the data carrying device comes from the reader by making use of the contactless technology. Because of this specific kind of power transferring and data carrying procedures, the contactless automatic identification systems are termed as Radio frequency Identification Systems.

What is RFID?

The term RFID stands for Radio Frequency Identification. Radio stands for invocation of the wireless transmission and propagation of information or data.… Read the rest

The Toyota Way Philosophy

Japanese quality movement was a miracle and created world-class products. All these methodologies and concepts developed these quality gurus for internal process and quality improvement crisis are still practiced in various companies. These have become universal approach to improve the quality and manage performance crisis.  Quality gurus created work culture and dedicated teams, which developed Japanese production systems through group activities. Toyota Corporation developed a new philosophy to create major change in manufacturing systems and delivered world-class products with internal benchmark for quality of vehicles. In reality, Toyota changed external business environment for competitors and created a long-lasting impact on automobile industry.

The Toyota Way is a set of principles and behaviors that underlie the Toyota Motor Corporation’s managerial approach and production system. It consists of principles in two key areas: continuous improvement, and respect for people. Toyota use operational excellence as a strategic weapon. Company places the highest value on actual implementation and taking action. By constant improvement based upon the actions, one can rise to the higher levels of practice and knowledge. Toyota success story can be summed up by using three models, which are used by Toyota Corporation. These models are explained below;

1. 4P Model

Toyota has developed 14 principles for performance improvement. These principles are guiding thumb rules in Toyota. These 14 principles are divided into four sections and a unique 4P model is developed. Major thrust is given on teamwork and a systematic approach is developed by using these principles. These 4Ps are Problem Solving, Process and Partners, Process, Philosophy.… Read the rest

Project Risk Management

Risk can be defined as uncertainty of outcome, whether positive opportunity or negative impact. Some amount of risk-taking is inevitable, whatever the project. There has to be a deliberate acceptance of some degree of risk because the value to the business makes it worthwhile. Project risk management includes the processes concerned about conducting risk management planning, identification, analysis (both qualitative and quantitative), responses, and monitoring and control on a project; most of these processes are updated throughout the project.

Risk management in projects involves identifying and assessing the risks in terms of impact and probability, establishing and maintaining a joint risk register, agreed by the integrated project team, establishing procedures for actively managing and monitoring risks throughout the project and during occupation on completion, ensuring that members of the team have the opportunity to engage in a dialogue that will promote agreement of an appropriate allocation of risk, updating risk information throughout the life of the project, ensuring control of risks by planning how risks are to be managed through the life of the project to contain them within acceptable limits, allocating responsibility for managing each risk with the party best able to do so. Management of risk is an ongoing process throughout the life of the project, as risks will be constantly changing. Risk management plans should be in place to deal quickly and effectively with risks if they arise.

Risks should be allocated to individual risk owners within the integrated project team, who should fully understand the risks for which they are responsible.… Read the rest

Knowledge Management Cycle

In today’s business scenario where there is lot of competition, only source of lasting is Knowledge. It is argued that knowledge management is a necessity due to changes in the environment such as increasing globalization of competition, speed of information and knowledge aging, dynamics of both product and process innovations, and competition through buyer markets. Knowledge management promises to help companies to be faster, more efficient, or more innovative than the competition. Also, the term ‘‘management” implies that knowledge management deals with the interactions between the organization and the environment and the ability of the organization to react and act

Various researchers then gave the various definitions on Knowledge Management and still it’s the buzzword today. Knowledge management is the process through which we can manage human centered assets efficiently and effectively. The function of knowledge management is to guard and grow knowledge owned by individuals, and where possible, transfer the asset into a form where it can be more readily shared by other employees in the company. KM refers to activities aimed at enhancing knowledge processing. These activities are interventions designed to affect how knowledge processing is done. The tools, techniques, and strategies to retain, analyze, organize, improve, and share business expertise. Knowledge management promotes an integrated approach to identifying, capturing, retrieving, sharing and evaluating enterprise information assets. These information assets may include database, policies, procedures and documents and as well as uncaptured tacit expertise and experience stored in the heads of individual workers.

Knowledge management is the information having some intent that can be interpreted and made available.… Read the rest

Disaster Recovery Plan (DRP) in Business

Fire, flood, earthquake and accidental deletion of data are all acts that can cause disastrous consequences on data. Such disasters can prevent the network from operating normally, which in turn can hamper the organisation’s business. These disasters can be classified into man-made disasters and environmental disasters. Man-made disasters are intentionally or unintentionally caused by humans. For example, a user accidentally deletes the data, virus and malicious programs can damage data and various other events can cause data loss and downtime. Environmental disasters are non-preventive but can be reduced if appropriate precautions are taken. Environmental disasters include fire, flood, earthquake, tornado and hurricane.

Disaster recovery deals with recovery of data that is damaged due to destructive activities. The time required to recover from a disaster depends on the disaster recovery plan implemented by the organisation. A good disaster recovery plan can prevent an organisation from any type of disruption.

Disaster Recovery Plan/Business Continuity Plan

A Disaster Recovery Plan (DRP) helps to identify threats to an existing business such as terrorism, fire, earthquake and flood. It also provides guidance on how to deal with occurrence of such events. Disasters are unpredictable; hence, planning for the worst is important for any business. A DRP is also called a Business Continuity Plan (BCP). The only difference between Disaster Recovery Plan and Business Continuity Plan is the focus. The focus of Business Continuity Plan is to provide continuity of operations in the organisation. Whereas, Disaster Recovery Plan focuses on recovery and rebuilding of the organisation after a disaster has occurred.
