Week 3

• there are software and hardware that needed in my project. other than that, i have to do some research about what is RFID and barcode. 

• In my case, this project focusing on budget planning during shopping time. in specific, if a customer have a certain amount of money that he/she plan to spend, he/she can scan the barcode of the item, and the balance price will show. so, when he/she wants to pay at the payment counter, they already know how much money they should pay rather than being chaotic during the payment.
