I put my chips in 2.5x2.5" cardboard holders and write the ChipGuide# on each one. If there is no location on the chip, then I write it on the back of the holder. If the chip is not in the ChipGuide, those without a ChipGuide# on the holder, then I scan it and submit it to the ChipGuide. This year I am using the new My Collection and Want List feature on the ChipGuide. I remove the chips I got at the convention from my Want List and then add them to My Collection.
