Sender & Receiver - Have to register for Mobile Banking & get a unique ID called "MMID"
MMID - Mobile Money Identifier (7 digit code) Each MMID is linked to a unique Mobile Number. Different MMIDs can be linked to same Mobile Number
Presently, IMPS Person-to-Person (P2P) funds transfer requires the Remitter customer to make funds transfer using Beneficiary Mobile Number and MMID. Both Remitter as well as Beneficiary needs to register their mobile number with their respective bank account and get MMID, in order to send or receive funds using IMPS.
There may be cases where Remitter is enabled on Mobile Banking, but Beneficiary mobile number is not registered with any bank account. In such cases, Remitter shall not be able to send money to the Beneficiary using Mobile Number & MMID.
Hence on the merit of the feedback received from the banking community as well as to cater the above mentioned need, the IMPS funds transfer has been made possible using Beneficiary account number and IFS code as well, in addition to Beneficiary mobile number and MMID.
IFS Code - 11 digit alphanumeric number, available in the users Cheque book.

Appropriate existing two-factor authentication method would be used for all the channels. The limit as prescribed by the bank for these channels would apply while transferring money using either of these channels.
While initiating an IMPS transaction using either ATM or Internet channel, mobile banking registration for a remitting customer is not mandatory. Similarly, for customers receiving money using account number/IFSC, or using AADHAAR number, mobile banking registration is not mandatory.
