In today’s ever fast growing world of boom the whole world is experiencing a fast growth. All the fundamental facilities are also growing. One such place where people can shop for almost everything is the mall.
-------------------------------------------------
As the malls have increased so has increased the no. of people visiting the particular mall. Today people have to wait in queue for the billing of their purchased products. This can be really inconvenient as may people are in a hurry and it is a sheer waste of time.
-------------------------------------------------
In this project we are making wireless billing system for malls. The main objective of the project is to reduce the time taken during the billing (no queues) since the billing is done wirelessly. Also to reduce the man power needed is less thus reducing the overhead cost of the system.
-------------------------------------------------
Rfid is the special type wireless card which has inbuilt the embedded chip along with loop antenna. the inbuilt embedded chip represents the 12 digit card number. Rfid reader is the circuit which generates 125khz magnetic signal. This magnetic signal is transmitted by the loop antenna connected along with this circuit which is used to read the rfid card number.
-------------------------------------------------
In this project rfid card is used as security access card. So each product has the individual rfid card which represents the product name. rfid reader is interfaced with microcontroller. Here the microcontroller is the flash type reprogrammable microcontroller in which we already programmed with card number. The microcontroller is interfaced with keypad.
