The popular option of buying gold has reached another dimension with the introduction of German vending machines. These machines are a step away from the old style selling of gold. This means that you would not need to go to a gold shop or a retailer to buy gold. Instead, you can just go to a shopping mall with these German vending machines, pay the money and get gold bars at the very moment. It is just like an ATM machine where you draw cash in an instant.

German vending machines work on the principle of dispensing gold bars and coins after a customer makes a payment. They have adopted this principle from the retail vending machines and the drink vending machines. A customer can get gold bars and coins in 1 gram, 5 grams and 10 grams denomination. Currently, these machines are installed in Germany. The location of these machines is still limited though they are installing them at all major shopping malls, airports and train stations.
