Our product solution, SILbar, is designed so that it can be used to easily process barter transactions. This involves exchanging silver granules for the desired goods. The condition for such a trade is that both seller and buyer have an S-Deposito of BB Wertmetall AG. The motto: “You give me what I need - I'll give you what you need”. Bartering is trending more then ever before. Particularly attractive are transactions based on silver granules.
