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.
