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.
I wonder how difficult it would be to make digital receipts into a simple PNG file that you can use your phone's NFC to transfer the image directly to your device from the PIN pad. I know I'd be more likely to actually get a receipt if the digital option was as simple as tapping my phone and saving an image; especially if it was through a local, ad-hoc transfer that didn't require transferring your data around the planet three times before getting a text message with a link to a website that may not even function a month from now. I feel like fixing the security of digital receipts would also fix a lot of the inconveniences that digital receipts currently present.
NFC would encourage phone upgrading which is worse for the environment than the problem they think they are solving. Paper is biodegradable. Phones are not.
Android 2.3+¹ supports bluetooth file transfers. This would avoid both the problem of using cloud energy and privacy problem (but only for smartphone owners who carry their smartphones). The article mentioned PDF being rejected. PNG could work, though it’d be a missed opportunity to get a digitally signed receipt. In any case, the paper receipt cannot be wholly replaced if it requires consumers to have a phone and to carry it, or if it requires sharing email addresses.
