> First customer walks in and gets a credit of $100. Now the customer wants to pay these $100 to someone who uses a different bank. What happens?

The first bank credits the account the different bank has with it in the amount of a hundred dollars. This involves updating a spreadsheet.

"Whenever a bank makes a loan, it simultaneously creates a matching deposit in the borrower’s bank account, thereby creating new money" [1].

That would only work if the two banks have an agreement. No established bank would make such an agreement with a bank that has no assets.
