Overview

The ATA Carnet real‑time lifecycle management system (ATA Carnet System) is built on a centralised and secure infrastructure that enables the end‑to‑end digital management of ATA Carnets.

At its core, the system relies on a central database that connects multiple components responsible for issuing, holding, validating, and processing carnets and customs transactions in real time.

System components

The ATA Carnet System consists of six components, grouped into:

• Two system integration interfaces
• Four user-facing applications

System interfaces

These components handle system‑to‑system communication and orchestration:

• ATA Carnet Core (ACO)
  The central backbone of the system, responsible for data orchestration, lifecycle management, and coordination between components.

• ATA Carnet NICS (ACN)
  The integration layer that connects National Issuing and Claims Systems with the ATA Carnet System.

User interfaces

These components provide access to carnet data based on the needs of each user type:

• ATA Carnet App (mobile)
  Used by carnet holders and representatives to carry the digital carnet, present it at border crossings, and receive transaction confirmations.

• ATA Carnet Desktop
  Desktop alternative to the mobile app for holders and representatives.

• ATA Carnet Customs (ACC)
  Application used by Customs officers to view carnets, validate information, and confirm transactions at the border.

High‑level system operation

The ATA Carnet System operates according to the following high‑level flow:

1. Carnet issuance

   • The holder orders a carnet through the National Issuing and Claims System (NICS) operated by the National Guaranteeing Association.
   • NICS systems are local systems and are not part of the ATA Carnet System.

2. Carnet download and sharing

   • The holder downloads the issued carnet into their smartphone wallet (ATA Carnet App or ATA Carnet Desktop).
   • If required, the carnet can be shared securely with a representative.
   • The carnet is encrypted at all times and is never transmitted in an open or readable format over the network.

3. Border crossing

   • At the border, the holder or representative unlocks their wallet and presents a QR code.
   • Each QR code corresponds to:
     • A specific carnet
     • A specific transaction (for example, export or import)

4. Customs validation

   • The customs officer opens ATA Carnet Customs (ACC).
   • The officer scans the QR code and views the detailed carnet information.
   • The transaction is verified and confirmed in the system.

5. Transaction recording and confirmation

   • Once confirmed, the transaction is securely recorded in the system.
   • A confirmation is sent back to the holder’s or representative’s device.

6. Claims detection and management

   • Customs authorities can:
     • Detect potential claims
     • Avoid unnecessary claims through virtual voucher reconciliation
   • Claims are managed in coordination with National Guaranteeing Associations (NGAs).
