Why aren't there solutions for electronic itemized receipt for retail in-store purchases? 
In some stores that is done. When I shop at the Apple store or at the Farmers market the receipt is automatically sent to my email address. Why don't others do it? If the target of the itemized receipt is a credit card company they would be sending data that they spent collecting to another corporation. The grocery store is collecting your data so they can sell it to their vendors. They sell to vendors the info that Gen X shoppers that buy cat food are more likely to use brand X laundry detergent then Millennials. The credit card companies could gather even more Meta data that they could sell. Privacy. Some people don't join the reward program at the store because they don't want a company to know exactly what they buy. Even fewer would want the credit card company to have that information.  The credit card companies would have to want this level of data that would have to be stored, maintained, and protected.
