Here is a story of how a traditional craft met modern technology through a "Portable Account" solution. The Weaver’s Ledger: A Tale of Two Generations

Months passed. The account grew stranger: it began to record things Vasparvans had not lived. It stored the scent of a foreign rain he’d never felt, a language he did not know, the name of a woman—Miren—whose hand he had never held. At night he woke with the echo of a lullaby the glass hummed softly into his dreams. He feared the cylinder was stealing truth. He feared it was granting him other lives.

If you are a person who rarely changes banks and lives entirely in one country using cash, the Vasparvans system might feel like overkill. Legacy banking works fine for that static lifestyle.
