Forced use of e-receipts in Europe → forced data sharing with MS and Google (no data minimisation?)

So here’s a disturbing development. Suppose you pay cash to settle a debt or to pay for something in advance, where you are not walking out of the store with a product. You obviously want a receipt on the spot proving that you handed cash over. This option is ending.

It’s fair enough that France wants to put a stop to people receiving paper receipts they don’t want, which then litter the street. But it’s not just an environmental move; there is a #forcedDigitalTransformation / #warOnCash element to this. From the article:

In Belgium: since 2014, merchants can choose to provide a paper or digital receipt to their customers, if they¹ request it.

What if I don’t agree to share an email address with a creditor? What if the creditor uses Google or Microsoft for email service, and I boycott those companies? Boycotting means not sharing any data with them (because the data is profitable). IIUC, the Belgian creditor can say “accept our Microsoft-emailed receipt or fuck off.” If you don’t carry a smartphone that is subscribed to a data plan, and trust a smartphone with email transactions, then you cannot see that you’ve received the email before you leave after paying cash. Even if you do have a data plan and are trusting enough to use a smartphone for email, and you trust all parties handling the email, there is always a chance the sender’s mail server is graylisted, which means the email could take a day to reach you. Not to mention countless opportunities for the email to fail or get lost.

It’s such a fucked up idea to let merchants choose. If it’s a point of sale, then no problem… I can simply walk if they refuse a paper receipt (though even that’s dicey because I’ve seen merchants refuse instant returns after they’ve put your money in the cash register).

But what about creditors? If you owe a debt and the transaction fails because they won’t give you a paper receipt and you won’t agree to info sharing with a surveillance advertiser, then you can be treated as a delinquent debtor.

Google, Facebook, Amazon, and Microsoft must be celebrating these e-receipts because they have been working quite hard to track people’s offline commerce.

It’s obviously an encroachment of the data minimisation principle under the GDPR. More data is being collected than necessary.

¹ This is really shitty wording. Who is /they/? If it’s the customer, that’s fine. But in that case, why did the sentence start with “merchants can choose…”? Surely it can only mean merchants have the choice if they make a request to regulators.
