Terms and Conditions for the Security Authentication Service of Dah Sing Bank, Limited


1. These terms and conditions ("Terms") apply to and regulate your use of the security authentication service, namely biometric authentication (including fingerprint / face ID authentication / facial recognition) and self-assigned security passcode authentication (collectively, the "Service") provided by Dah Sing Bank, Limited ("the Bank" or "we" or "Dah Sing"). By registering or using the Service, you agree or are deemed to accept and agree to these Terms. If you do not accept these Terms, please stop registering or using the Service.

2. The Service (i) provides you an alternative means to log into Dah Sing Mobile Banking Service ("Mobile Banking"), Dah Sing e-Banking Service ("e-Banking") and/or Dah Sing i-Securities Internet Trading Services ("i-Securities"); and (ii) allows you to (instead of using the Security Code (defined in the Master Terms and Conditions of the Bank)) give instructions and make applications to the Bank through the Internet or other electronic means acceptable to the Bank via our Dah Sing Bank Mobile Application (the "App") by using your biometric authentication record(s) stored on your designated mobile device* or self-assigned security passcode.

*Designated mobile device means a mobile device which is compatible to the App and Service as may be announced by us from time to time. Please contact us for the updated list of such designated mobile devices.


3. By activating the Service, you agree that Dah Sing may treat and consider as valid and binding on you any instruction given, or agreement made with Dah Sing, which is authenticated through the Service without Dah Sing making any further inquiry as to the authority or identity of the person making or purporting to give such instructions or to make such agreement or their authenticity notwithstanding any error, misunderstanding, fraud, forgery or lack of clarity in the authorization. You acknowledge and agree that Dah Sing may still, but is not obliged to, require you to authenticate a transaction by your password and/or another form of authentication even though you have authenticated the same through the Service.


4. The Service is provided as part of the Bank's services, and accordingly:

4.1. These Terms are in addition to and shall be read in conjunction with the Bank's Dah Sing Bank Mobile Application User Agreement (the "Agreement") and any other documents forming part of our banking agreement and any reference to the terms and conditions of the Agreement shall include reference to these Terms; and

10.1 you must use the scanner provided in the App;

10.2 you must complete the login within 100 seconds upon the appearance of the QR code. If you failed to do so, you should refresh the page or wait until the original QR code expires to receive a new QR code; and

The probability of a false match using face ID authentication and facial recognition varies in some cases, such as for twins or siblings who look alike or adolescents, and the disabling of "Require Attention for Facial Recognition" function from your device settings. Please accept the associated risks and consequences if you continue to enable the face ID authentication and/or facial recognition.

You hereby agree that your access to or the availability to you of the App after the relevant effective date of such revised Terms shall constitute your acceptance of such revised Terms.


21. The Chinese version of these Terms is for reference only. Should there be any inconsistency or conflict between the English and Chinese versions of these Terms, the English version shall prevail.
