Can I pay for Tbilisi public transport with a bank card, and does a foreign card work?

A bank card linked while abroad (e.g. in Russia) works fine in the Yandex Taxi app for routes within Tbilisi, though it may not work on other services.

Currency exchange in Tbilisi isn't always favorable — rates can be poor even at nearby exchange points, so it's better to have a local or fee-free international card.

Yandex Taxi works fine and lets you choose cash payment; a ride from the airport to central Tbilisi costs around 30 GEL.

With a local card (TBC or Bank of Georgia) paying for transport within Tbilisi is fee-free; foreign cards may have conversion fees charged.

Marshrutkas heading from Tbilisi to Rustavi don't accept bank cards — cash is required, while within Tbilisi itself card payment works.
