SHOPPING RECEIPTS AS ANALOG SCREENS

We all came across shopping receipts, as they are part of our daily life, but usually thrown away after approximately two seconds and creating a toxic waste

In our project, we aim to show you why we think it is a fascinating material and how to deal with it in your daily life.

A receipt you get at a shop is regularly a thermoreactive material. This means that once you heat up the surface of the paper it changes it’s attributes, in our case it’s the colour. After a while reheating it gets brighter temporarily and then turns black again if you can do the same precisely it could almost work as a black and white analog screen. To take advantage of this characteristic, we have developed some techniques which are described in detail in the booklet below.
