Immediate Payment Service (IMPS) is an initiative of National Payments Corporation of India (NPCI). It is a service through which money can be transferred immediately from one account to the other account, within the same bank or accounts across other banks. Upon registration, both the individuals are issued an MMID (Mobile Money Identifier) Code from their respective banks. This is a 7 digit numeric code. To initiate the transaction, the sender in his mobile banking application need to enter the registered mobile number of the receiver, MMID of the receiver and amount to be transferred. Upon successful transaction, the money gets credited in the account of the receiver instantly. This facility is available 24X7 and can be used through mobile banking application. Some banks have also started providing this service through internet banking profile of their customers. Though most banks offer this facility free of cost to encourage paperless payment system, ICICI bank and Axis bank charge for it as per their respective NEFT charges.
Nowadays, money through this service can be transferred directly also by using the receiver's bank account number and IFS code. In such case, neither the receiver of the money need to be registered for mobile banking service of his bank, nor does he need MMID code. IMPS facility differs from NEFT and RTGS as there is no time limit to carry out the transaction. This facility can be availed 24X7 and on all public and bank holidays including RBI holidays.
