Hawaii now has Medical Marijuana dispensaries. Because the banking system will not service these businesses for fear of Federal retribution, the business deals only in cash. Of course this is a potential problem for thefts. So now the state is strongly encouraging the dispensaries to adopt a smartphone app for cashless purchases. The payment app is a Colorado-based Credit Union that also handles a lot of Colorado payments and has good experience with this. I guess the Credit Union gets around some of the federal banking rules and regulations enforcement since it is a state-based financial institution.
Looks like an area that Bitcoin could make some inroads.
And it looks like the over-reaching feds are slowly being ‘deClawed’ in the financial enforcement sector.
