Research of RFID

Radio-frequency identification (RFID) is a technology that uses communication via radio waves to exchange data between a reader and an electronic tag attached to an object, for the purpose of identification and tracking.

It is possible in the near future, RFID technology will continue to proliferate in our daily lives the way that bar code technology did over the forty years leading up to the turn of the 21st century bringing unobtrusive but remarkable changes when it was new.

RFID makes it possible to give each product in a grocery store its own unique identifying number, to provide assets, people, work in process, medical devices etc. all with individual unique identifiers – like the license plate on a car but for every item in the world. This is a vast improvement over paper and pencil tracking or bar code tracking that has been used since the 1970s. With bar codes, it is only possible to identify the brand and type of package in a grocery store, for instance. Furthermore, passive RFID tags (those without a battery) can be read if passed within close enough proximity to an RFID reader. It is not necessary to “show” them to it, as with a bar code. In other words it does not require line of sight to “see” an RFID tag, the tag can be read inside a case, carton, box or other container, and unlike barcodes RFID tags can be read hundreds at a time. Bar codes can only read one at a time.

With RFID technology we can create variety future  in Wellington . I was thinking create touchscreen based panels, such as “Street Window Shopping” and “info Wall”. “Street Window Shopping” is touch screen based pannel which shows us latest fashion info and comparing prices between shops without visiting all the shops in Wellington. Depend on what people registered their info in RFID , it displays each person’s size info, favorite style, what’s on SALE, map of shops and etc. “info Wall” is quite similar to “Street Shopping Shopping” with different informations. This will have all the informations about Wellington which can be very useful for the tourists. It will displays weather, transit timetable, what’s on, map, today’s special, entertainment, dining and bar info in Wellington on LIVE.

Another thing we can use of RFID is payment by Mobile phones. Since summer 2009, two credit card companies have been working with Dallas, Texas-based DeviceFidelity to develop specialized microSD cards. When inserted into a mobile phone, the microSD card can be both a passive tag and an RFID reader. After inserting the microSD, a user’s phone can be linked to bank accounts and used in mobile payment. Many countries already using this now.  This will be handy for many Wellingtonians who carry around too many different cards.
