Jeff Arend's Funny Car team had those made to hand out in the pits at every NHRA national event beginning in Topeka in May 2004. They had a different chip for each race.

I'm not sure whose idea it was to have these made, will ask Jeff when the tour hits Denver next month. It could have been him or someone on his team who had paid a visit to GGS when they were racing in Las Vegas in April 2004, or it could have been Urban Casavant, the Prez and CEO of CMKX, the team's sponsor. The company is Las Vegas based. ...kind of a strange company. Diamond mining, publicly traded, 700 billion shares outstanding, usually bounces around between $0.0001 and $0.0002 per share.
