A valid question about bank transfers

There are certain financial events that seem to happen online instantaneously. When we buy something with a credit or debit card, it comes out of our balance immediately. When we purchase something with PayPal, it comes out of our balance within minutes. When we wire cash from one account to another, it takes no time at all.
The question in this week’s Joy of Tech asks a good question. The only thing better than the question is the answer. RIP.
