What is the difference between Axis Bank Currency Exchange & Online money transfer?

Could you elaborate on the key differences between Axis Bank's Currency Exchange service and their Online Money Transfer option? As a potential customer, I'm interested in understanding how these two services vary in terms of convenience, fees, exchange rates, and the overall user experience. Does one offer more flexibility or better value compared to the other? Are there any limitations or specific advantages to each? Additionally, is there a difference in terms of safety and security between these two modes of transfer? Your insight into these aspects would greatly help me make an informed decision.
