There was only gold bullion
The world of banking has changed significantly throughout the last couple of years. It is impossible to compare the system used to conduct work in a bank fifty years ago and now. Today"s banking is based mainly on computers. Actually, frankly said today everything is connected to the computers somehow. It is hard to find a branch of business which has not been floated online yet. Maybe tattoos, they still cannot be done virtually. But of course there is the possibility to make an appointment online using mails or special systems of communication offered by the company"s website... there must be the chance to see the patterns and tattoos in a virtual catalogue, you can pick up your favorite pattern or whatever and just come to the place and get it done instantly. Why am I talking about tattoos instead of banking? Because this is all similar. Nowadays you also can do everything online, deal with all the formalities online. There is actually no need even to leave the house because you can make a remittance online and in this way you handle all the banking stuff from you comfortable chair at your own place. The only thing that has not changed since very long time is the matter of gold bullion. The reserves of money in a bank are usually stock in a gold bullion. If you know what I mean. From time to time there is platinum instead of gold bullion, that"s all.
