One time, I set a self-checkout machine to French to immerse myself in French training in Canada. This happened to set the payment terminal to French as well, which must have set a bit in the on-card chip. Now, all my pay-at-the-pump interactions at gas stations are all in French. A website I was purchasing from flipped to French when I entered my card info. There were a few surprise interactions where my language preference was clearly derived from my bank card setting. I’m just hoping that being classed as bilingual is doing wonders for my “social” score at some clandestine data clearinghouse.
