No, they're electronic bank-notes or bearer bonds of some kind. The magnetic strip and probably a RFID chip contains the anti-counterfeiting data. They are pre-loaded with a certain amount of credit and can't be 'topped up', only used and later recycled by the banks.

It's unlikely that Roman would be paying for loot with a few used tens or twenties, so they are likely for several thousand Lien each.

I've heard similar ideas thrown around about using such things in the real world.
