The photographs of Shinhwa will appear on transport cards. This card is a USB key and used to pay public transport fees.
What differentiates this from other transport cards is that users do not need to run to subway stations or bus stops to reload them. They can quietly do it with the use of the Internet. One should connect it to a computer and go to a special Internet site. This new card can be used to travel around Seoul.
According to Good Entertainment, Shinhwa's label, the manufacturer of the transport card decided to put the photographs of the 5 members on the new product because Shinhwa is one of the most famous male group in the country.
