Pump clicked off finished filling at exactly $100! So satisfying. (Notwithstanding high fuel prices, c'est la vie)

How could we possibly steal fuel when we already presented our credit card? Fuel won't even begin pumping unless we scan our credit card first.
If you have notifications for transactions you'd see a 100 pending transaction. Then the moment you finish pumping it would be updated to actual value. At least Wise does this at Costco, either going above or below 100, haven't noticed it with other cards so it depends on not only the issuer but maybe the pump itself.
Come to think of it, your card issuer maybe doesn't allow for updating transactions after the fact, so perhaps that's why it stopped at 100? It sounds useful, except for getting fuel heh
In the USA, they all do, to allow for things like tips at restaurants. The initial payment is just a hold, then they adjust the value before finalizing it.
Why would a tip be charged after the rest of the bill? The top has to be a approved at the time of payment, otherwise the waiter could just add in whatever tip they felt like and update the charge. It's to allow for exactly this scenario, deposits on self-serve items or things like hotel rooms where there may be additional charges due to damage or mini-bar use etc.
I'm not sure where you live, but in the USA at a restaurant, the server takes your card, runs it in the PoS system, brings it back to you along with a receipt, and then you hand-write the tip amount on the receipt. Some of them bring a portable payment terminal to you, but it's the same idea.
When they give the receipt back to you for you to write the tip, the payment has already been authorized. It's already been sent to your bank, in a pending state, and your bank has replied saying the transaction will be approved. One of the receipts will have an authorization ID/number from your bank.
When you write the tip, they enter that into their PoS to modify the transaction amount, and finalize the transaction.
That can actually happen. A lot of the time, issues like that are accidental (eg they typo the tip amount).
That's a wild system. In Canada they bring the terminal to you, you put in the tip amount and then your card is charged all at once. Or at some places they'll bring you the bill and you can write in your tip, and then you take the bill up to a counter to pay. This only occurs in very small family restaurants usually though. Before chip and pin got popular they would still bring the bill and you would write in your tip, and then they'd take the bill and your card back and charge it all at once. Why would they take your card before you write in the tip, that doesn't even make sense and just creates an extra step.
Yeah, the USA is weird when it comes to banking and financial services.
Sounds like Canada is similar in Australia. At a lot of places in Australia, you pay when ordering. Sometimes you pay at the end. Aussies don't really do tips though, and prices must always include tax, so it's a lot simpler. Something on the menu is $20, you pay $20. That's it.
Yeah I've seen those, they usually approve for just $1. But that doesn't mean they shut off the pump after you pump one dollar or 100 dollars worth of fuel.
