BOC even with hardware token, if transfer large sum of money, it will require a second authentication through OTP to get through.
My account got locked recently when I transfer big sum of money out.
They tried to call me a few times to verify but I did not pick up call. So they lock my account.
Dear customer, we noticed multiple or large outflow of funds made via digital services with your BOC account. The Bank has attempted to contact you regarding these transactions but we were unable to reach you. As we are unable to verify these transactions, the Bank will temporarily deactivate all services (including electronic banking services and GIRO services) linked to your account as a safeguard. If the transaction was made from a joint-account, please kindly inform your joint-account holder. Please contact BOC hotline or head down to any of our branches for assistance to reactivate your account.
My only complaint about BOC is the staff handling banking calls are not fluent in english (don't have this issue for credit card). Have difficulty understanding them. And they are not able to unlock but have to refer to team. End up have to go to branch which could unlock on the spot.
