Bpay.io is designed to support as many digital currencies as possible, realizing their internal translation into the currency, which the main seller wants to accept as his/her basic currency. If, for example, the seller selects EUR as the basic currency on his/her internal account, when the client pays for the goods or services in Ethereum/ Bitcoin/etc, the seller receives the payments in EUR with a possibility of further transfer to his/her bank account. One of the long-term objectives of Bpay.io apart from serving a payment gateway in the virtual envi- ronment is integration into offline economy. As the most relevant analogues we can mention Square (https://squareup.com) – a project that offers offline sales outlets a simple mechanism of accepting and accounting digital currencies as a payment method.
