The contactless card reader, such as an RFID tag reader, can be located so as to provide additional space for another transaction component. The contactless card reader can also be used in conjunction with a magnetic stripe card reader.
The ATM is able to prevent dispensing of currency in situations where unauthorized detection of signals is sensed. An RFID tag is an object that can be 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.
A basic RFID system consists of three components: There are many different types of RFID systems out in the market. They are categorized according to there frequency ranges.
Some of the most commonly used RFID kits are as follows: The cost of the system is based according to there ranges withlow-frequency system ranging from a few hundred dollars to a high-frequency system ranging somewhere near dollars.
An antenna or coil A transceiver with decoder A transponder RF tag electronically programmed with unique information These are described below: Antennas are the conduits between the tag and the transceiver, which controls the system's data acquisition and communication.
Antennas are available in a variety of shapes and sizes; they can be built into a door frame to receive tag data from persons or things passing through the door, or mounted on an interstate tollbooth to monitor traffic passing by on a freeway.
The electromagnetic field produced by an antenna can be constantly present when multiple tags are expected continually. If constant interrogation is not required, a sensor device can activate the field. Often the antenna is packaged with the transceiver and decoder to become a reader a.
The reader emits radio waves in ranges of anywhere from one inch to feet or more, depending upon its power output and the radio frequency used.
When an RFID tag passes through the electromagnetic zone, it detects the reader's activation signal. The reader decodes the data encoded in the tag's integrated circuit silicon chip and the data is passed to the host computer for processing.
At its most basic, the chip will contain a serialized identifier, or license plate number, that uniquely identifies that item, similar to the way many bar codes are used today.
A key difference, however is that RFID tags have a higher data capacity than their bar code counterparts. This increases the options for the type of information that can be encoded on the tag, including the manufacturer, batch or lot number, weight, ownership, destination and history such as the temperature range to which an item has been exposed.
In fact, an unlimited list of other types of information can be stored on RFID tags, depending on application needs. An RFID tag can be placed on individual items, cases or pallets for identification purposes, as well as on fixed assets such as trailers, containers, totes, etc.Due to many impressive features of microcontrollers, any engineering student like to work on the projects based on microcontrollers.
