Proposal for a device that converts the printed content of receipts into tones

Abstract

Receipts are made of thermal paper, which is difficult to recycle, and no two are alike. In other words, they are valuable life logs. In response to the fact that receipts are often not received at checkout, or are simply discarded after being received by the customer, we propose a way for receipts to be more than "just something to be thrown away. We decided to give new value to receipts by making them "audible," and created a device to make this possible.
