- Suspicious transactions — fraud or unauthorized charges.
- Card compromised — phishing, skimming or data leak.
- Leaving the UAE permanently — close cards before exiting.
- Account closure — debit card must be cancelled before closing the account.
- Card no longer needed — switching banks or upgrading.
