Digital receipts offer a few improvements over (tradition) paper receipts. One is health-related. Lots of receipt paper contains bisphenol—A, or BPA. This chemical can completely influence or outright change some bodily processes, like hair growth, hormone function and cell repair. (reduce) receipt paper reduces the risk for BPA exposure for not only consumers but also for employees who handle the paper a more routine basis.
Another reason why digital receipts are better just boils down to (convenient). You can access those receipts through your email and file (they) away in a separate folder or with a specific label for easy sorting. Or, if you need more help on the organization front, try a receipt tracking app. Physical receipts require you physically (keep) track of them, and that means a shoe box or an accordion folder or a big thumb tack on a cork board in the kitchen. There have been times when I've let something go unreturned I didn't have the receipt. I'm betting I'm not alone on that.
Some businesses, particularly local ones, use newer point of sale systems like Square that will (automatic) send you a digital receipt if you've already received one from another business that uses Square. When you pay with the same credit you did at the first seller, and you've already provided email address to the Square system, you (get) a receipt in your email minutes later.
