Both the company and the bank have identified the need for Despite encountering various restrictions when working
a receipt-less solution due to several reasons: with the bank due to security constraints and operational
procedures, the team proposed modifications to the kiosk
1. Paper wastage: Paper rolls are typically changed at the machine codes, including:
beginning of the day, resulting in the disposal of remaining
paper from the current roll. • Upon successful deposit, the receipt will be displayed on
the screen instead of printed directly.

printed receipt, leading to instances where receipts are left • A ‘PRINT’ button will be available on the screen, allowing

Eco-Solutions
The ESI team proposed implementing a receipt-less option
(Figure 3) for the cash-bag deposit machines to address the
environmental concern related to paper usage and power
consumption. This solution allows customers to choose
whether or not to print a receipt. Instead of automatically
printing receipts, customers can view their receipts via QR
code scanning or on-screen display for a photo snapshot. By
offering this alternative, a reduction in power consumption
at each bank branch and a decrease in paper usage is Figure 3
possible, ultimately providing a greener and cleaner option
for bank branches.
