## Understanding the Role of Acquirers

In digital and traditional commerce, acquirers act as intermediaries connecting merchants,
[issuers](https://www.corbado.com/glossary/issuer) (banks providing cards to consumers), and payment networks.
Their primary functions include:

- **Payment Authorization:** When a customer initiates a transaction, the acquirer
  receives the payment details from the [merchant's](https://www.corbado.com/glossary/merchant) system and
  forwards this request to the card [issuer](https://www.corbado.com/glossary/issuer) via payment networks. The
  [issuer](https://www.corbado.com/glossary/issuer) either approves or declines based on available funds or fraud
  checks, and this information is relayed back through the acquirer.

- **Transaction Settlement:** Acquirers facilitate the transfer of funds from customers’
  bank accounts to merchants’ accounts, typically within one to two business days. They
  [reconcile transactions](https://www.solvexia.com/blog/transaction-reconciliation) and
  handle the associated fees with payment networks.

- **Merchant Onboarding and Compliance:** Acquirers evaluate new merchants before
  approving [merchant](https://www.corbado.com/glossary/merchant) accounts, checking credit history, business
  legitimacy, and compliance with standards like
  [PCI DSS](https://www.corbado.com/blog/pci-dss-4-0-authentication-passkeys) (Payment Card Industry Data
  Security Standard).

## Importance of Acquirers for Merchant Success

Acquirers directly impact [merchant](https://www.corbado.com/glossary/merchant) revenue and operational
efficiency through:

- **Smooth Payment Flow:** Efficient payment processing reduces transaction times and
  minimizes customer friction, increasing sales conversions.
- **Fraud Prevention:** Acquirers provide merchants with advanced fraud detection tools,
  such as risk scoring and behavior analytics, significantly reducing chargebacks and
  losses.
- **Integration Capabilities:** Modern acquirers offer integrated payment solutions,
  including APIs, SDKs, and passkey-enabled authentication methods, allowing merchants to
  implement seamless checkout experiences.

## Acquirer vs. Issuer: Key Differences

Acquirers and [issuers](https://www.corbado.com/glossary/issuer) are distinct but complementary components of the
payment ecosystem:

| Acquirer                                          | Issuer                                               |
| ------------------------------------------------- | ---------------------------------------------------- |
| Handles merchant transactions                     | Issues payment cards to consumers                    |
| Provides merchant accounts and payment gateways   | Manages customer accounts and card balances          |
| Settles funds to merchants                        | Approves or declines customer transactions           |
| Focused on merchant-side security and integration | Focused on customer-side security and authentication |

## Why Passkeys Matter for Acquirers

As transaction security becomes increasingly vital, acquirers adopt advanced
authentication methods like passkeys. Passkeys offer several benefits:

- **Enhanced Security:** Eliminates the risks associated with traditional passwords, such
  as [phishing](https://www.corbado.com/glossary/phishing) or
  [credential stuffing](https://www.corbado.com/glossary/credential-stuffing) attacks.
- **Improved User Experience:** Faster, frictionless payments lead to higher customer
  satisfaction and lower [cart abandonment](https://www.corbado.com/blog/ecommerce-authentication) rates.
- **Reduced Fraud Rates:** Passkey authentication significantly reduces the likelihood of
  fraudulent transactions, protecting merchant revenue and reducing chargebacks.

By integrating secure authentication solutions such as passkeys, acquirers maintain
competitive advantages, boost merchant confidence, and ensure robust, trustworthy payment
systems.
