Changing credit cards or even savings bank accounts is easy these days (no need to visit branch or anywhere). Plus, credit card numbers expire even when you don't change the card bank.
However, you certainly have a number of direct debits set up at different places - some are monthly, some could be quarterly or yearly and some are saved payment details on various apps/ websites/ with institutions. On the other hand, you may have your bank account set up as a credit option for any refund, payment, cashback, etc. Unfortunately, there's no automated way to check where all you've your card registered for direct debit/ credit and get a precise list of all places so that you can update them. The only way to check is going by a yearly statement, transaction by transaction, so that you don't miss any possible association of the card or bank account and you can list them and update them all. I feel that it's a big deterrent when it comes to change of card number or bank account number for any reasons. How do you manage this process generally? Just looking for some tips or thoughts.
