Can you pay for multiple passengers with a bank card on Tbilisi public transport?

On Tbilisi city buses you can pay for multiple passengers with a single bank card by tapping the validator once per person.

Minibuses to Sarpi (Turkish border) may display signs saying transport card only, but a foreign (non-Russian) bank card is accepted directly on board, so a separate transport card isn't necessary for just a couple of trips.

Tbilisi transport cards are available at metro stations and dedicated kiosks — useful as a backup if your bank card isn't accepted on a particular minibus.
