A system incorporating method and associated apparatus for establishing virtual banking in a merchant venue or syndication of merchants for one or more consumers in a manner that increases the deposit-based assets of a related traditional banking institution by loading transactions of fractional currency amounts, preferably reflecting the acquisition of physical fractional currency, and more preferably coinage, and thereupon enabling inter-merchant (or syndicate) commercial transactions, including purchases and sales, in a manner that does not deplete deposit-based assets. Commercial transactions are at the direction of consumer(s) each with their own portable device linked to a merchant-hosted virtual account that maintains transaction details, histories and balances, and transmits data reflecting the same to the portable device(s) where it is recorded and displayed, upon demand. Also included are devices for executing commercial transactions with the portable device(s) and transmitting appropriate data to each bank and virtual account.
