I figured they would - guess the question is would they (could they?) jump on people who do alter chips, and therefore have the technology to alter chips, but haven't necessarily altered that casinos chips (yet)?

I guess this is intent to, or ability to, defraud rather than actually doing it and so probably does not infringe any laws, but I was wondering if a casino could use the arguament of trademark infringement to close down such an operation, thus eliminating the possibility of fraud (by the repairer or unknowingly to him/her their customer) in the future.

Again, just my thoughts while the board is quiet (one of the disadvantages of a 5-8 hour time difference!). Jason
