>0.3% vs. 3-4%No, the total costs of handling cash currency & coins for large businesses will still add up to 3% or more which is in the range of the fees of credit-cards processing. Costs of accepting cash also includes:
- paying for armored trucks and security guards to transport bags of cash to the bank
- percentage of cash lost to crime such as
--- employees/cashiers theft/skimming by handling cash,
--- robberies,
--- counterfeit bills

For a business, a true arbitrage of not paying 3% credit-card fees would be convincing customers to pay by check or electronic ACH bank account withdrawal. Those payment methods avoid the costs of managing loose cash and also avoid the fees from the credit-card processors. But they also have the same privacy concerns as CCs if customers care about that aspect.
