GrabPay: do not pay a personal QR from chat
Use only the verified cashier route and confirm payee, amount, fees, refund rules and withdrawal availability before approval.
Values to record
Minimum and maximum amount, possible fee, provider, processing estimate, account-ownership requirement, refund route and transaction reference.
Security boundary
Never share online-banking credentials, card PIN, wallet PIN or OTP. Authorise only the exact payee and amount you reviewed.
