Plates
Dissections of payment flows
Every payment system is two clocks: the one the user watches and the one the money obeys. Each Plate lays a flow open part by part, with both clocks on the table.
Plate II Dissection of a UPI payment Transactio unificata — one scan-and-pay, laid open as observed 2026-07-06 Plate III Dissection of a card purchase Emptio chartacea — one online checkout, laid open as observed 2026-07-06 Plate IV Dissection of an embedded loan Creditum insitum — one working-capital loan, laid open as observed 2026-07-07
Plate I — dissection of a cash payment — remains in preparation. The oldest rail resists the table: it is the only one where both clocks strike at once.
