Robert,
The Mason co made these same claims "registered monograms," "non-duplicate checks." "protected chips," "exclusively yours," etc."

On some chips I have as many as 5 different cards for 5 different people in 5 different parts of the good ole USA. Some orders do have a different color or two in them, it is the only way you can pin a chip on a certain customer.

I am not saying that is true about USPC as I have never seen it with their chips.
