Device and method for sequencing paricipation in a point-of-sale activity
First Claim
1. A device for sequencing participation in a point-of-sale activity using tokens, where each token has an identifier, comprising:
- a sequence accumulator comprising a First-in-First-out (FIFO) buffer for holding token identifiers, including a first identifier at the top of the FIFO buffer;
a sequence announcer communicating to the sequence accumulator, wherein the sequence announcer receives and announces the first identifier;
an advance commander communicating to the sequence accumulator wherein the advance commander advances the FIFO buffer;
a token input for receiving a token having a second identifier;
a token reader for reading the second identifier;
a comparator communicating with the sequence accumulator and the token reader and having an output communicating with the point-of-sale activity, whereby the comparator receives the first and second token identifiers and when the identifiers match, directs the output to activate the point-of-sale activity.

Abstract
In a device for sequencing a point-of-sale activity, identifiable tokens are used to orderly queue participation. The device announces a token identifier for a next participant, and the participant deposits a token into a token input. A token reader reads the identifier from the deposited token, and a comparator compares it to a previously announced identifier. If the identifiers match, the comparator directs the point-of-sale activity to start. Additionally, a method for queuing a point-of sale activity that includes the steps of dispensing a token having an identifier, placing that identifier in a First-in-First-out buffer, advancing the buffer each time a new participant is needed, announcing that identifier, accepting a token, reading the identifier from that token, matching that identifier to the one announced, and activating the point-of-sale activity.

15. A method for sequencing a point-of-sale activity comprising the steps:
-
dispensing a token having a first identifier; placing the first identifier in a First-In-First-Out (FIFO) buffer; advancing the FIFO buffer each time a new participant is needed for the point-of-sale activity; announcing the first identifier on a sequence announcer when the first identifier is at the top of the FIFO buffer; accepting the token; reading a current identifier from the deposited token; matching the current identifier to the first identifier; activating the point-of-sale activity.
