Taxi and Transport Apps in South Korea: real experience from chats
Short answer
For taxi services in Korea, use Kakao T with the 'Pay to Driver' option to settle fares via cash or T-money card. For trains, simply present the QR code directly from the Korail app to staff or scanners, as paper tickets are unnecessary.
From real experience
Uber's international version may not function within Russia.
After updating the application, Uber may become functional in South Korea. The option to pay with cash typically becomes available only when the user is physically present in South Korea and using the service domestically. Ensure the app is set to the correct region for local payment options to appear.

To pay for taxi rides in Korea via apps like Uber, the 'pay in car' option depends on the city's infrastructure and user profile.
If the option is missing, try restarting the app. KakaoT also supports English interfaces and cash payments, which is often more reliable for tourists than global taxi apps.

To use Kakao T without a local credit card: choose 'General' taxi during booking and select 'Pay to Driver' (pay by cash or T-money card in the vehicle).
A local phone number is often required for the app, but some users report success with international numbers.

QR codes for Korail train tickets are scanned directly at the station.
If requested by train staff, the QR code in the app serves as your ticket. No paper ticket exchange is typically necessary.
