(ii) comply with all manuals, guides or directions we or the card schemes give you
from time to time regarding the authentication procedures; and
(iii) unless we agree otherwise, send us an authentication request each time a
cardholder wishes to purchase goods or services from you on your website
using their credit card; and
(iv) carry out any additional authorisation procedures which arise out of
authenticated transactions and of which we advise you in writing; and
(c) you must not change your payment processing systems, equipment or any bureau
you use for the purposes of the authentication procedures unless we have fi rst
certifi ed the proposed change to any of them; and
(d) if you send us an authentication transaction, or a transaction (other than a
commercial card transaction) that you attempted to authenticate but couldn’t

authentication), which we then authorise and process, we will not charge it back
to you on the basis that the cardholder claims that they were not the person who
purchased goods and services from you on your website; and

and may be varied by them from time to time. You agree to comply promptly with
any new or different requirements of which we notify you; and

time. We will endeavour to give you reasonable notice of this decision. Upon receipt
of that notice you must immediately return to us the password and any other guides
and materials we have given you in connection with authentication; and
(g) after termination or during any period of suspension of authentication we will
process your transactions as if you had never been a participant in authentication
and the usual chargebacks will apply.
