What's the Difference Between an Acquiring Bank & an Issuing Bank?
The acquiring bank and issuing bank are both important to accept payments, but their roles are very different.
Acquiring Bank
A merchant acquirer refers to a bank or financial institution that represents the business in a transaction. The acquiring bank enables a merchant to collect payments made during credit or debit card transactions.
The merchant acquiring bank receives the money from the issuer and ensures the payment is processed and completed, depositing the money into the correct merchant's business account. That account is the merchant account: without one, a business has no way to receive card funds, which is why every merchant that accepts cards is connected to an acquirer, either directly or through an intermediary.
An acquirer is also responsible for complying with the security standards implemented by the Payment Card Industry Data Security Standards Council (PCI DSS). If the acquiring bank fails to implement the necessary security measures, it will be liable in the event of a data breach or if a cardholder's information is stolen.
Moreover, acquirers carry a financial risk. If a chargeback occurs (when a customer disputes a charge and requests for the transaction to be cancelled or the funds returned), the acquirer is liable for repaying the issuer. Supplying this service carries a substantial cost for merchant acquirers as they require the internal resources to review chargeback requests.
They may offer a line of credit to a business to cover these costs. However, if the business claims bankruptcy or becomes insolvent and is unable to pay, then the acquiring bank must accept the loss.
To reduce this risk, businesses often go through a vetting process before a merchant acquirer decides to represent them, assessing and limiting their financial risk and liability. This merchant underwriting typically covers KYC checks on the company and its owners, processing history, and the industry the business operates in. It is also why some verticals are classed as high-risk and face stricter terms or declined applications.
A merchant acquirer is not always the same entity as the payment processor. The acquirer holds the card scheme licence and the merchant relationship, while a payment processor supplies the technology that switches and settles the transactions, often on behalf of several acquirers. Many merchants also buy acquiring through a Payment Service Provider (PSP), which resells an acquirer's services together with a gateway and onboarding, without holding scheme membership of its own.
Issuing Bank
In comparison, an issuing bank means the institution representing the customer in the transaction. They can take the form of a traditional bank, credit union, or other financial institution. The issuing bank supplies an individual with the debit or credit card they use to initiate a transaction.
As such, they take the risk of issuing credit to an individual. To do so, issuers consider the creditworthiness of an individual based on their credit score and financial history.
Once approved, they issue a card which enables the individual to access a line of credit. The loans offered are usually unsecured (no collateral or security is required to guarantee repayment).
However, the customer's bank can collect interest if the loans are not paid back by their predetermined deadline. If the customer is unable to do so, the issuer becomes liable for the debt and, therefore, responsible for the initial transaction.
Issuing banks also handle chargebacks, serving as the arbitrator and determining whether the customer's request is reasonable.
