|"This seems more likely than the free teleportation depicted in other novels. After all, somebody will spend millions (or more likely billions) developing the technology, and will want to earn back the money.

|"The coin slot would work the same way as with a candy machine. When the correct or minimum amount of money is inserted, you're sent to your destination.

While cell phones have replaced phone booths, using a debit or credit card is standard on most transactions. A self-checkout in a grocery store will take a card or cash."|
