Smart Billing System Using Arduino

The modern technology has increased the standard of living for the humans. With the advancement of technology, the level of acceptance of people of all ages towards electronic gadgets is increasing steadily. Electronic gadgets such as barcode scanner smart card reader and RFID scanner are gaining more and more usage in various kinds of industries. So with the help of these we came up with this innovative project is of an automated billing system which can be placed at a side where the customer is flexible to use at any time. This automated payment system consists of a RFID reader which is controlled by Arduino. So, whenever the customer places the tag it is detected by the RFID module and is displayed on LCD along with the price of the item. As the customer goes on adding items, all items are detected by the module and therefore the price will increase accordingly. In case if customer changes his/her mind and doesn’t want any item added to the bill he/she can remove it and the price added will be deducted automatically. At the end of the entire process the total amount to be paid will be displayed. We can also pay the bill using the mobile application in the app itself. The mobile application is operated by the Wi-Fi module used in the hardware implementation. After the payment the bill will generate successfully. Hence this technique is an appropriate method to be used in places like hotels so this will help in reducing manpower and helps in making a better billing experience for customers.
