Investors have traditionally considered gold as a 'safe haven' amid financial uncertainties.

However, gold bars are not exactly easily transportable - until now.

Swiss refinery Valcambi, a unit of US mining giant Newmont, has created the 'Combibar', which are gold bars the size of a credit card that can be easily broken into one-gram pieces, and can be used as payment in an emergency.

"The rich are buying standard bars or have deposits of phsyical gold. People that have less money are buying up to 100 grams," Michael Mesaric, CEO of Valcambi told Reuters.

"But for many people a pure investment product is no longer enough. They want to be able to do something with the precious metal."

Mesaric also told Reuters that its advantage is that it can be easily transported and costs less than buying 50 one gram bars.

"The produce can also be used as an alternative method of payment," he said.

The 'Combibar' has also been compared to a chocolate bar due to the fact that it can be broken off by hand into one gram squares.

Andreas Habluetzel head of the Swiss business of Degussa, a gold trading company told Reuters that the product is popular among grandparents who 'want to give their grandchildren a strip of gold rather than a coin'.

Take a look at how Combibars are created.
