The tool on the cover of PayPal Hacks is a money changer. The money changer is a container clipped to one's belt that stores, organizes, and dispenses coins to facilitate making change on the go. It is typically divided into four barrels, so that pennies, nickels, dimes, and quarters can be held separately. The money changer is extremely useful for people who need to make frequent cash transactions while in transit, and is often used by train conductors and traveling vendors.

Jamie Peppard was the production editor and proofreader for PayPal Hacks. Brian Sawyer was the copyeditor. Darren Kelly and Claire Cloutier provided quality control. Judy Hoer wrote the index.
