PAYMENTS SIGNAL · REFERENCE CARDCard clearing & settlement
The authorisation only promised. Now Demo Coffee Ltd's captured sale becomes a clearing record, interchange is applied, net positions settle between Meridian Bank and Bank Alfa, and Maya Chen's hold becomes a real debit — through Cardnet, a fictional card network standing in for Visa/Mastercard-style networks. (SYNTHETIC / TRAINING ONLY)

Exception rails
| Rail | Trigger | Where the money ends up | Next action |
|---|---|---|---|
| Rejected: record fails clearing edits | One clearing record fails Cardnet's edit checks — a malformed field, or presentment after the window the network's rules allow. | Maya's money stays under the authorisation hold — her final debit waits for a successful presentment. · The rejected record misses this cycle's net settlement and settles with a later one after repair. | Meridian Bank — Meridian Bank corrects and re-presents the record inside the network's presentment window. |
