Having stated this, I also do clearly appreciate the challenges before the banks which ranges from identification of various delivery channels, decision making on whether to leverage on existing technology or adopt a big bang approach, extension of the existing risk management practices to various delivery channels, acquisition of all these transactions over the existing settlement networks, adoption of various services as part of their existing crossselling and co-branding initiatives, fraud prevention and security standards, safeguards against money laundering, KYC issues and, above all, ability to leverage their existing reporting, auditing, and campaign management at back end.
