You are a shop owner ...

Do away with payment terminals : create an account for your shop and you can junk your payment terminals ! Both you and your employees can instantly start accepting payment for your products directly, on their mobile phones, with the crypto directly reaching your account. No installation required.

Accepting payment directly from the customer into your account means no bank or other financial intermediary involved, and no « interchange » fees.
Accept differed payment : your customers can pay for your products in advance, from the comfort of their home, and leave you a note about coming to pick them up later!
No need to print a receipt, the transaction is always available on the blockchain !
"Once a customer, always a customer!". You can build a direct relationship with paying customers and let them know in the future about special offers and promotions in a non-intrusive way.
Accepting BTC is a great way to appeal to a dedicated population of « bitcoiners ». Accepting HBD and saving them (instead of cashing out) generates a high APR (currently 15% per year).
