RTGS (Real Time Gross Settlement) is the fastest possible money transfer system through the banking channel. Because settlements are made in real time, transactions are not subject to any waiting periods. So, you get funds within no time. All banks have this facility for their customers and they charge very nominal fees for this service which is nothing as compared to sending funds using old methods.
For sending funds using RTGS facility all banks have their own forms and set their timings. Most banks set limits for sending funds in a day. Generally people can send minimum 2 lakhs and maximum 25 Lakhs using Net Banking Feature. But if you have to transfer more than 25 lakhs, you have to visit your branch.
I have listed RTGS and NEFT Forms of All Banks below, just download and use these for sending funds.
