Nowadays, as per the rules and regulations of RBI, the card holders can withdraw cash from any bank’s ATM, he/she need not be restricted to the bank’s ATM where the account is present. And as many people use debit or credit card, they frequently exercise this facility, due to financial or medical emergency sometimes, location restrictions, bank limitations on no. of transactions of own debit or credit card per month etc. In financial terms, these types of transactions are called OFF-US transactions: where the issuing bank (the bank which has issued the card to the customer) and acquiring bank (the other bank whose ATM you intend to use) are different entities. The current system of handling such OFF-US transactions has few drawbacks, f irstly, the consensus is not achieved amongst the involved banks and secondly, regarding discrepancy or mismatch of transaction status in case of failure during interbank transactions via NPCI, where the card holder is unable to withdraw cash from ATM, yet money is deducted from his/her account. Due to these limitations, the reconciliation process is very time consuming, and the card bearer suffers a lot due to delay in settlement for amount deducted. To overcome the above-mentioned drawbacks is the purpose of this research undertaken. We intend to introduce distributed ledger technology that is Blockchain Hyperledger Fabric to achieve transaction consensus amongst the involved banks and NPCI and to also ease the reconciliation process.
