UX for efficient usage of thermal paper rolls

I have been to the outlet's mall for Christmas Shopping and all I see for any tiny purchase is a long receipt. Honestly, I only care about the final price, tax, and discount information. I was curious to know how these long receipts catch the attention of others and if they really even care about the additional information.

As we all know 2020 has been a very challenging year for all of us, even nature by itself suffered many burns.

I went ahead and took this up as an assignment and started to question and know from people and friends regarding the information in these receipts.

Who are these “People”?

Men, Women, Mom, Dad, Grand Parents, Children, Teens, Boys, and Girls

Questions asked:

• Is the information on these long receipts helpful?
• Do you even care to look at the additional information?
• What do you always focus on a receipt?
• Did you any time lookup for any information on the receipts, was it helpful any time?

Answers

All of them only said they don't really look at any information on these receipts except for the final price and discounts.

The address of the store, which might be useful during a return purchase. They all mentioned one thing in common that everything is available online from deals to help desk information and that is a more preferable way to contact rather than typing in a number/website looking into a receipt.

Note: The numbers in the receipt are for illustration purpose only

Using the Measure app in iPhone and after doing the math, my design is saving 63% paper usage of the original receipt.

As per the article listed below, considering the bar code keeps track of the transaction ID which can pull all the data. I have decided to remove certain details that the user will not be in need of. In addition, the backside of the receipt can be used for any additional information related to the store and its policies.

An efficient UX design can help save trees!
