UV is outdated and really has no value since anyone can put UV on a chip.
The Palms B&G rack chips have a laser TAG. Only the Palms can read it. We have laser reader, the mark in the ink is tuned to a frequency only we can read. We were the 1st in the US to have it.

UV and laser is soon to be obsolete. The big casino companies have signed on to use a new and unique system of chip tracking. Not sure when it is debuting but most will have to have new chips, millions of them.
