BINGO / Scan Device

In Taiwan, when you buy some things in a store, you will get a receipt that attached a string of numbers. Once every two months, the government will announce some numbers that the consumers can compare with their receipts’ numbers to check if their receipts win a prize.
Then, many foundations collect many receipts from our society to win many prizes to help many people who are disadvantaged but the foundations do that by manual labor! It wasted so much time and labor!! Therefore, BINGO takes advantage of scan technology to help the foundations to compare with so many receipts.
