In the 1980s, the National Railroad Administration started to issue Railroad Membership Cards. This membership card only had a 10-digit membership number on it, this type of card is widely used until 1998. In 1998, quick-ticket machines and a new membership card with a magnetic strip were introduced. Although the quick-ticket machine had many benefits, the machine and new card were not widely used. The current version of KTX Family Card with IC chip (Smart card) was introduced in 2004.^{[citation needed]}
