TicketQR is a free Android application developed by WAKO Co. Ltd. that allows users to easily and conveniently pay for public transportation using their smartphones. The app is designed to work with the TicketQR system, which has been implemented in various public transportation systems, including buses and trains, in the Ueda City area of Nagano Prefecture in Japan.

TicketQR enables users to pay for public transportation using various electronic payment methods, including PayPay and dPAY, as well as credit cards. Users can also purchase prepaid tickets for regular use or discounted tickets for students and individuals with disabilities. The app can read QR codes printed on paper media for those who don't have access to smartphones.

The app has been widely adopted by Ueda City residents and visitors, and has been used as a payment tool for the city's consumption promotion campaign, which offers discounts of up to 20% for purchases made at participating stores. The app is easy to use and offers a convenient way to pay for public transportation without cash.
