A comment on Uber Freezes Hiring of U.S. Tech Staff as It Seeks to Cut Costs. Parent comment
1. Authenticate the transaction (is this ‘uber’ Company ok and is it reasonable this user is using it for fraud detection)
2. Check that the users balance + the cost of the trip < the users credit limit
3. Post the change to a transaction log
4. Some hours/days later, finalize the pending transactions.
That’s a whole lot simpler (outside of fraud detection) than what Uber has to do to get you from A to B.
