@Altin#218902 If you're ever unsure about the status of a card payment, if you click on it you can then choose "Show more" and then tap on the small blue text "Do you need help with this payment?". In this menu there's an item "Show payment history" where you can see exactly what the status of the payment is. Expired reservations also show the amount crossed out as soon as the money has been refunded, so you always know if the money has been deducted from your balance or not at a glance. If you export a bank statement for an account, it also has the account balance of the starting and end dates printed on it, and refunds of reservations etc. are listed separately so if you want to make sure their books are correct, this would a good way.
At times I worry if the actual reservation is really a reservation or is actually a charge.
I would argue that for bookkeeping purposes, this is not really relevant here, because both reservations and "actual" charges both get charged to your account in the same way with your account balance decreasing. The only difference is that the merchant will refund the reservation after some time (in most circumstances, that is) and your account balance will increase again after the refund/expiration of the reservation charge. In the backend, these are two transactions, so you should probably also treat them as such.
Normala’ banks don’t show such transactions.
It's true that some bank opt to not directly show transactions to users, but other credit cards work the same way internally. Let's say you have a credit line of 1000 Euros at a bank, if you rent a car and have to make an 800 Euro deposit, you won't be able to buy anything for more than 200 Euros afterwards because your credit line is used up. Only after the merchant has released the deposit, the respective amount of your credit line is available again. At bunq you don't have a credit line in the first place, you can only have a positive account balance. If they wouldn't show you certain charges, then many people would run into a situation where payments would decline even though their account balance is high enough on paper. Deposits/Reservations aren't just there for fun and games, the money has to be actually reserved somehow and be accessible to the merchant in case something happens (for example you crash your rental car in a tree). And bunq can only guarantee for this by deducting money from your balance the same way other banks deduct deposits from your available credit.
