Here’s an excerpt from the original patent specification describing the wearable credit card transaction terminal that eventually became the Orang-Otang™ Jango™ point-of-sale terminal.
FIG. 44 shows a Key Palette equipped with a magnetic strip reader (441), a small keypad, and a roll of paper (442) for use with an internal printer. Such a device can be used for taking credit card information, which is wirelessly transmitted for approval, and then printing a receipt for the transaction, all while on the go. Not pictured is a similar device which includes a larger keypad (with miniature keys including the whole alphabet and ten digits) and printer into which blank traffic tickets can be fed. This device is ideal for people who check parking meters.
