Of course, if your chipped card is stolen and pinless tap is supported for small purchases, no transaction verification helps you to avoid fraudulent charges. And if someone has your card and knows your pin (which still can be skimmed with card skimmers), then you are likely on the hook for all transactions up until you report your card stolen.
I work in the area. In the EMV specification the receipt content is already saved electronically and is somewhat standardized, see, for example https://www.mastercard.us/content/dam/mccom/global/documents/transaction-processing-rules.pdf. What is missing is for the consumers and point-of-sale owners to be able to access it easily. The receipt does not identify the product sold, by the way, but enough details to verify the transaction’s occurrence.
