1. Blocking RFID Readers from Reading our information by-Naiteek mishra

2. WHAT IS RFID? Radio Frequency Identification (RFID) refers to a wireless system comprised of two components: tags and readers. The reader is a device that has one or more antennas that emit radio waves and receive signals back from the RFID tag.

3. ABSTRACT OF THE PROJECT If you've ever watched an adult pay for something by simply touching their credit card to a machine at a store, or you've done the same with a bus pass, you've seen an RFID tag in action. An RFID (Radio-Frequency IDentification) tag allows a card to be read by a computer from a short distance away. This is very convenient, but it also allows criminals to steal information about you. For instance, on the subway or the bus, someone standing next to you can use an RFID reader to access the data on that card. After learning what materials can be used to block an RFID reader, you can design a solution to protect your cards and your passport.

4. HOW DOES THE RFID SYSTEM WORK? Let us look at how RFID systems work, and how you can use that knowledge to improve privacy and security to better safeguard your personal information. An RFID tag is a miniature radio station. It has a radio transmitter connected to a computer chip and when asked, will turn on the transmitter and broadcast the data that it has. That may sound like how your cell phone works, for example, but there is a huge difference. Your cell phone has a battery that has to be kept charged and it can transmit data for many kilometers. An RFID tag has no battery that you have to charge (a  passive RFID  tag has no power source at all, while an  active RFID  tag has a small battery used only when responding) and can't transmit very far. In addition to the computer chip and radio transmitter, the RFID tag also has energy-harvesting parts.

5. HOW DOES THE RFID TAG GENERATE ENERGY?  A coil antenna is tuned to a specific  frequency . When the reader wants to get information from the tag, it sends out a signal at the tag's specific frequency. The energy from the radio signal is converted to just enough power to start up the computer chip, energize the radio transmitter in the tag, and send back the tag's data. The reader gets the signal back, extracts the data it needs, and turns off. The tag is now unpowered and goes dead until the next read.

6. WHAT IS THE RFID CYCLE?

7. PHYSICAL MATERIALS REQUIRED Computer with at least one USB (universal serial bus) port, as well as Microsoft® Windows® XP or better USB RFID reader kit with sample tags USB cable (mini USB) Bricks, wooden blocks, cardboard boxes, or some other sturdy non-metallic object for holding the reader and tags steady Tape Scrap cardboard to protect the work surface Measuring stick or ruler, metric Aluminium foil Scissors

8. SOFTWARES REQUIRED For Windows computers: HyperTerminal software, which may already be installed on the computer PuTTY Or some other serial terminal emulator
