International and certain domestic payments are made by AIB via the Belgium-based Society for Worldwide Interbank Financial Telecommunication (SWIFT).
SWIFT processes payments on behalf of financial institutions worldwide and is currently the only organisation providing such a service. All transactions processed in Belgium are replicated in a backup system ('mirror site') in the United States of America (US).
Maintaining a geographically separated back-up infrastructure to ensure continued operation is in line with international standards and supervisory requirements.
On foot of official subpoena(s), transaction data held in the US 'mirror site' may be disclosed to US, or other authorities for the purposes of combating terrorism and other serious crime. Therefore, any information you provide to AIB in order to effect a SWIFT payment could potentially be disclosed to US authorities, and by instructing AIB to execute a payment, you are implicitly giving your consent to such a disclosure.
AIB reserves the right to amend this notice at any time, and you should regularly check for any amendments.
