The peer to peer payments system ran into problems at its launch earlier this year, which a bank spokesman at the time attributed to difficulties dealing with the large amount of traffic.
However, on the whole, what is happening in Asia compares favourably to progress elsewhere, according to Bottomly, who was speaking on the sidelines of an INSEAD forum on Saturday titled "Re-imagine Asia: the new digital frontier".
"I think the pace of change of what is happening in digital banking is happening faster in Asia, both on the consumer side and the regulatory side, and also when it comes adoption of technology like cloud," he said. "If you extrapolate from that, you may see that financial services as a whole will innovate faster and go to a newer place."
When it comes to technology in financial services, the pace of change in mainland China has been rapid, as shown by the latest flood of tech Chinese firms seeking to list in Hong Kong.
HSBC is also embracing fintech in its mainland China operations, and Bottomly said the bank has been using chatbots to help customers set up new accounts as part of the bank's expansion in China's south eastern Guangdong province.
"If there is a common set of questions, as you get when many customers are looking to open new accounts, then it is easier for a chatbot," he said.
