My friend group all use the same one though to pollute the data.
Use cash for this strategy. If you’re using credit or debit cards they can separate the data that way.

Check out the Target story from years ago where a dad went mental that they sent vouchers for baby stuff to his pre 16 yo daughter.
Turns out they knew she was pregnant before the family.
Point being. Data is scary powerful at scale. Tesco in the UK is holding us hostage to get a card as literally half the items are cheaper with one. My friend group all use the same one though to pollute the data.

Don’t phone pay wave apps provide a temporary number?

Good point. I believe they do generate a temporary virtual card number but I’m unsure if it removes all potentially identifying information from the transaction.

In Australia there are numbers set aside exclusively for use in fictitious TV shows and stuff, to avoid idiots trying to call characters from TV or movies.
The ACMA publishes a list of these numbers. The first on the list is 0491 570 006.
Whenever I’m asked for a card I just say I forgot it and get the cashier to look it up with that number. I’ve never had to sign up since I started doing this.
Pro tip: often times the cashier will look surprised and ask your name, because they will be looking at dozens of other names that have used that number. Just ask who’s listed, pick one of the first ones and say ‘yeah Skye, that’s my girlfriend’ or whatever. Weird but it works.
