Seoul Metro in South Korea will introduce a “tagless” fare payment system, allowing passengers to pay for their tickets by simply walking through a ticketing gate without having to tap a contactless reader with their transit card or smartphone. The system will utilize Bluetooth Low Energy (BLE) technology and mobile sensor devices to automatically charge the fare to a payment card stored on the passenger’s smartphone as they pass through a subway gate.

The trial of this new payment system will take place at four metro stations in Seoul, with plans for a full rollout across nine lines next year. The selected stations include Yongdap Station on Line 2, Oksu Station on Line 3, and Dongjak Station and Sadang Station on Line 4. The goal of the trial is to achieve at least 95% accuracy for the system’s location determination technology within the next six months.

During the trial, the system’s recognition technology for boarding and alighting from the subway, payment processing speeds, and fare and transaction data will be thoroughly inspected. Once the technology passes the testing process, Seoul Metro intends to expand the use of the tagless fare payment system to all passengers throughout the entire railway system by next year.

Seoul Metro announced its plans to trial the tagless Bluetooth fare payment system in July 2022. This initiative aims to streamline the payment process for passengers and enhance convenience for users of the Seoul Metro transportation network.
