Make secure online payments using your OTP
Extra security with OTP messages
Every time you purchase online with your Be1st Smart TPN UnionPay card, you will receive a One Time Password (OTP) sent to your mobile phone to confirm your transaction.
No more memorizing
Instead of having to remember a password, you will receive a new OTP each time this means that no-one else can copy and re-use your password as long as you have your mobile phone in hand you can easily access your password.
If you would like to update your mobile phone number previously registered with Be1st card, you can contact any Bangkok Bank branch nationwide.
