I'm talking about your typical local mom and pop type places (coffee shop, hair dresser, convenient store, dry cleaner, etc.). Let's say you ask if they take Bitcoin. You explain what it is and how they can save money off of transaction fees vs. credit cards. They're in.
Where do you point them to start taking Bitcoin? Coinbase and Bitpay are the two biggest payment processors I'm aware of. I could help them download a wallet on their own smart phone, but I think if they are going to accept Bitcoin for any customer, they'll probably want to use a payment processor.
What is the minimum amount of tech they'll need to get set up to accept BTC? A smart phone or tablet?
