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.
