Anti-Scam Verification Guidelines

  • The "Safe-Back" Rule: If an agent claiming to represent a bank or authority contacts you with urgent demands, hang up and dial the official number on the back of your card.
  • No Screensharing: No bank support rep or police officer will ever require you to download Zoom, AnyDesk, or TeamViewer to "authenticate details".
  • Guard OTPs: One-time SMS passwords are keys to your account. Sharing them is equivalent to handing over physical keys.
