[Special Economy=Eunji Kim]It has been reported that the two consortiums, that have been selected to become Korea's very first internet banks, will each have no more than 300 employees at the maximum.

Respectively having only one or two percent of the number of a commercial banks's full-time workers, Kakao and K-bank will compete with these regular offline banks.

By looking at the number of employees working for each of these two, the Bible story of "David and Goliath" comes to mind.

In the tale, David is an underdog, outfitted only with a sling who has to fight Goliath, an experienced warrior with all the modern weaponry. In the end, it is a lesson that improbable victories by a weak party, in this case, David, can happen.

Experts are seeing the same happening for internet versus commercial banks. The internet banks, here, are an underdog, only considering they have far less workers than commercial banks. But, they can, nevertheless, come out on top, in the competition.

That's because they have factors that appeal to consumers—higher interest rates, online accessibility and convenience.

Moreover, Kakao-bank is said to have around 170 employees—65 in IT, 100 in human resources, service, management and other main departments. A part of the workers will be outsourced through financial technology institutions.

The reason for this contrast in how many are employed by the internet banks, as compared to commercial banks, is due to the different business models for each of these two.

Internet banks do not necessarily have to have that many workers as services are conducted online such as through messengers.
