This is a personal finance question related to retail shopping. I am wondering why, with the evolution of the Web and relatively well-established credit card payment system, there is still no widely implemented solution for being able to get an electronic copy of itemized receipt of in-store purchases? (e.g. an electronic copy of your grocery receipt that lists every item purchased and its price).
The data is certainly available and probably retained in the corporate databases and extensively used for consumer analytics, sales forecasting, marketing, etc.
The email information is often also available to the retailer through the use of club/reward cards, since when you sign up for those you typically input email address. Alternatively, the retailer can transmit the itemized sale information to the credit card company, linked to the total transaction amount on the credit card activity statement (I am thinking a drop-down menu that expands to reveal itemized detail of the purchase when viewing the online credit statement).
In any case, it seems we have the data and we have the technology. So it's not that.
There is probably also real value in delivering such information to the customer. It would save forests by reducing the need for all those mile-long printed receipts (paper vs. electronic receipt can be a voluntary opt-in/opt-out option at checkout, just like paper or plastic).
It also solves the issue of not having the paper receipt when you need it later (say, if you buy a small appliance in a brick-and-mortar store, but don't keep the receipt which is later needed for warranty service/replacement of the product).
Then what is preventing this service from being offered? If you are in the corporate retail/marketing/banking business and have a good educated guess/insight, your answer would be especially appreciated but anyone is welcome to weigh in thoughts. Thank you.
