When using credit card in Korea, we have to write sign not on paper but on liquid crystal display. Therefore, every shop has this system. However, surprising point is in other place. Korean people’s signs are gibberish.
At first, I thought they are writing joined-up English but it was totally different. Their signs have no meaning at all. One of my friend write emoticon at one time. He said, “Sometime I add tear to this emoticon if I feel some sadness. Today, I feel good so it’s smiling!”
I thought the security level of Korean credit card is not so high.
