Real-life example
Rajiv is buying a flat and needs to pay Rs 75L to the builder. He uses RTGS -- money reaches builder's account within 30 minutes on the same working day. A NEFT transfer for Rs 75L would also work now (24x7) but RTGS is the traditional choice for very large, time-sensitive transfers.
