Real-Time Gross Settlement (RTGS), is one more option that comes into the picture for online money transfer with the bank account. It is called real-time gross settlement because the transfer happens in real-time and the settlement is not done in batches but on a one by one basis. Currently, the RTGS enabled bank branches in India are up to 1,40,000.
