Not only is it time-consuming to store paper receipts, but also they take up a lot of space. It is not easy for users.

 People and businesses need to keep and organize receipts for a range of purposes including to track item spending, giving and receiving refunds and reimbursements, preparing financial statements, and for tax purposes. People keep receipts in folders, bags, and purses and are thus likely to get lost, while businesses rely on workers who may be careless to follow their storage procedures.
