1. RADIO-FREQUENCY IDENTIFICATION (RFID) By Jay Chahal

2. 3 DIFFERENT APPLICATIONS OF RFID  Navigation systems for the visually impaired – to help people with a walking stick can help them know where things are.  Clothes – RFID can be used in shoes and clothing to make access to different things easier to do.  Smart dust – RFID tags will become so small one day and that they will be all over the world and updating how the world looks in a real time manner.

3. RFID REPLACING BAR CODES  Today when we shop we can use a till or a self check out service, this is used by scanning our items through a scanner, as time progresses RFID will become smaller and smaller to a point were they will be nano-scopic and can be placed on food packaging so instead of scanning each individual item through we can just put our shopping in a trolley and walk out the shop and everything would be scanned through in a second and the total price would be added up and people can use contactless cards to pay a lot faster. Services using RFID will increase service speed.
