Upass (Korean: 유패스) is a prepaid card for the transportation system in Seoul and its suburbs. This card is issued by Seoul Bus Transport Association and eB Card. Its parent-generation card is Seoul Transportation Card, a world-first commercial-used RF card for transportation (first used in June 1996)¹. The Korean system integrator Intec and Seoul Bus Union first launched a test of their system in a trial from October to December 1995. Old Seoul Transportation Card and T-money can be used along with Upass.
Upass, and older Seoul transportation card system is based on MIFARE Standard, Ultralight and PROX technology.
Many kiosks around Seoul sells various types of Upass cards. Major banks and credit card companies, including favored Kookmin Bank and BC Card, issue Upass compatible credit/debit cards marked with PayOn, MasterCard, Paypass or Visa Paywave. Upass is accepted by:
- All Seoul, Gyeonggi-do, Incheon, Cheonan, Asan buses
- Seoul Subway and AREX
- Some Gyeonggi-do intercity buses. These buses are marked with yellow and orange 'Transportation Card Acceptance' stickers. Note that Gyeonggi-do intercity buses often run between other areas.
