In order to be able to claim warranty on an item or return it to a store, you need to be able to provide proof of purchase. The retailer will then use the information to locate your purchase in their systems and validate your request.
Some of our retailers will display a barcode within your digital receipt that you can use to return your items. Simply have the cashier scan your barcode at the till and they'll be able to locate your transaction.
If your receipt doesn't contain a barcode, the key piece of information retailers need to process your return is the receipt ID, which is located at the bottom of your digital receipt. You'll notice that receipts from food and beverage retailers won't generally include this information, but you'll always have it for transactions where you've bought goods - such as transactions made at schuh or H&M.
The benefit of using Flux digital receipts rather than relying on paper receipts is that your Flux receipt will never get lost - it'll be there in your banking app for you whenever you need it. Easy!
