ABSTRACT:
The invention provides a payment folder having a signal device for communicating to a server a patron's readiness and urgency to pay a service establishment's bill. In one embodiment, the signal device includes at least one battery powered light, such as a light emitting diode, mounted on the payment folder so as to be visible to an observer. The light(s) are illuminated in one or more colors and may be caused to blink in response to appropriate positioning of a control switch that can include a control circuit. In other embodiments, the signal device is a manually positionable colored surface, such as a flag, attached to the payment folder. Signaling is accomplished by withdrawing the colored surface from within the payment folder or by positioning the colored surface so that it is visible through an opening in or a transparent portion of the payment folder.
