Where could one find more information on RFID Tags?
RFID stands for Radio Frequency Identification and the tags are intelligent bar codes that can talk to a networked system to track every product put into your shopping cart. Information can be found at HowStuffWorks and then go to the article How RFID Works.
Is RFID an input or output device?
RFID tags are polled input devices. The computer must send out a radio frequency polling request and any RFID tags that recognize the request transmit back their reply code (including ID info.). The computer must then sort out the various codes it received back. If there is more than one RFID tag responding at the same time, this sorting must still be performed successfully at the computer so that all RFID tags will be correctly logged.
How the RFID technology avoids misuse of RFID tag in attendance system?
Radio-frequency identification (RFID) is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.Radio-frequency identification comprises interrogators(also known as readers), and tags (also known as labels).Most RFID tags contain at least two parts. One is an integrated-circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal.There are generally three types of RFID tags: active RFID tags, which contain a battery and can transmit signals autonomously, passive RFID tags, which have no battery and require an external source to provoke signal transmission, and battery assisted passive (BAP) which require an external source to wake up but have significant higher forward link capability providing great read range.The EPCGlobal standard (uhfc1g2_1_1_0-standard-20071017.pdf from EPCGlobal) defines four classes of tags as class 1, class 2, class 3 and class 4. Each successive class has higher functionality than the previous one and is also backward compatible. Apart from these four classes, sometimes class 5 is also referred by users in the industry which are nothing but RFID readers.RFID has many applications, for example, it is used in enterprise supply chain management to improve the efficiency of inventory tracking and management.Tell me if that helps you out.
What is RF-ID?
Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is an object that can be attached to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio frequency (RF) signal and perhaps other specialized functions. The second is an antenna for receiving and transmitting the signal. View the Google Video: Understanding RFID for a great introductory video on RFID
How RFID works?
Long checkout lines at the grocery store are one of the biggest complaints about the shopping experience. Soon, these lines could disappear when the ubiquitousUniversal Product Code (UPC) bar code is replaced by smart labels, also called radio frequency identification (RFID) tags. RFID tags are intelligent bar codes that can talk to a networked system to track every product that you put in your shopping cart. Imagine going to the grocery store, filling up your cart and walking right out the door. No longer will you have to wait as someone rings up each item in your cart one at a time. Instead, these RFID tags will communicate with an electronic reader that will detect every item in the cart and ring each up almost instantly. The reader will be connected to a large network that will send information on your products to the retailer and product manufacturers. Your bank will then be notified and the amount of the bill will be deducted from your account. No lines, no waiting. RFID tags, a technology once limited to tracking cattle, are tracking consumer products worldwide. Many manufacturers use the tags to track the location of each product they make from the time it's made until it's pulled off the shelf and tossed in a shopping cart. Outside the realm of retail merchandise, RFID tags are tracking vehicles, airline passengers, Alzheimer's patients and pets. Soon, they may even track your preference for chunky or creamy peanut butter. Some critics say RFID technology is becoming too much a part of our lives -- that is, if we're even aware of all the parts of our lives that it affects. In this article, you'll learn about the types of RFID tags and how these tags can be tracked through the entire supply chain. We'll also look at the noncommercial uses of RFID tags and how the Departments of State and Homeland Security are using them. Lastly, we'll examine what some critics consider an Orwellian application of RFID tags in animals, humans and our society.
Are there computer security lock systems for the home?
There really aren't any in mass market for doors. However, individuals do often make custom ones which are keyed to RFID tags that one would keep on a keychain.
How can you tell if your credit card uses rfid?
The only RFID embedded Credit cards I know of are the one that Say PAY PASS I believe master card introduced them, However there is only one way to know for sure and thats if you have an RFID reader/Scanner, RFID is so advanced their is no way to see it they are so small they could hide them in the dot of an i and you would never know

I want to do personnel positioning in the mall what product can support and What about Real Time Location System?
In Hangzhou China，Ecived Electronics and Technology Co.,Ltd developed a highest accuracy real time location system(RTLS), which reaches a revolutionary location accuracy of 5 cm, with the active RFID all functions. The system can be widely used in supply chain management, indoor navigation, assets tracking management, personnel security management, and other areas. One system consists of one base station, four ultrasonic (US) transmitters, and several tags.
