I'm interested in starting a business that sends customers rolls of quarters (and maybe at most 1-2 per week at most), e.g. for paying for laundry washing and drying machines. I'd like to be able to accept credit card payments (only) but I haven't yet found a payment processor that will agree to do business with my (potential) business.
Several prominent online payment processors seem to prohibit this type of business from
There was previously a U.S. business, Washboard, that attempted to offer this product/service, but they only remained in business for a few weeks and they stated that their payment processor prohibited their business's activity.
What is it about the business that's legally problematic for payment processors? What are the relevant laws?
