What is Mastercard?

Mastercard is an international corporation that operates a global financial network. Through this network, it facilitates electronic funds transfers (EFTs) using branded debit, credit, and prepaid cards. As an intermediary between financial institutions and businesses, Mastercard supports payment processing by authorizing, clearing, and settling transactions.

Built on a foundation of interoperability and scalability, Mastercard’s network is a key part of global commerce infrastructure. It can handle a wide range of payment types—from business-to-business (B2B) to person-to-person (P2P) payments—across borders and currencies. Mastercard also offers advanced analytics, payment gateway solutions, and anti-fraud systems, catering to the diverse needs of everyone from individual customers to global accounts, enterprises, and platforms that handle high transaction volume.

Mastercard’s services, based on application programming interfaces (APIs), integrate with a variety of platforms and offer flexibility to businesses that require customized payment solutions. The network also extends its functionality through strategic partnerships, bringing value-added services such as rewards programs, supply chain financing, and digital identity verification.

The network’s reach also spans a variety of financial environments, including retail, ecommerce, governmental organizations, and financial institutions. Businesses across sectors—from hospitality to health care—accept Mastercard-branded payment options. While it initially gained prominence through point-of-sale (POS) terminals, its scope has broadened considerably with the rise of digital payments.

Mastercard’s global payment network is used extensively for both personal and commercial transactions. With more than 1.1 billion credit cards actively in circulation, it ranks among the most used payment systems worldwide. Here’s an overview of its presence around the world:

How Mastercard works

Mastercard as a business financial provider

Mastercard offers a wide range of products to meet the varied needs of businesses, whether they are small operations, large corporations, or digital platforms. Mastercard plays a significant role in cross-border transactions, supporting businesses that operate in multiple markets. Multicurrency functionalities allow for transactions across different currency zones, simplifying international trade and ecommerce.

Below are some of Mastercard’s offerings for businesses:

• Mastercard business cards: Cards that include a standard credit card offering with expense management features
  
• Mastercard corporate cards: Cards designed for larger organizations, offering centralized billing options
  
• Mastercard Corporate Fleet Card: A specialized card for companies with vehicle fleets, providing detailed reporting on fuel and maintenance expenses
  
• Mastercard Send: A service that facilitates fast and secure payment disbursements to various endpoints
  
• Mastercard B2B Hub: An automated accounts payable solution that simplifies payments and integrates with existing software
  
• Mastercard Track: A secure, digital ledger that facilitates the exchange of transaction data and payments between buyers and suppliers
  

Mastercard also supports a variety of specialized transactions beyond traditional retail settings. These include B2B payments, digital wallets, and mobile payment systems. Global enterprises often use Mastercard’s capabilities for disbursement solutions and treasury operations, making it a versatile provider for handling complex financial activities.

Mastercard as a card network

In addition to the services and products it offers to businesses, Mastercard operates a huge network for facilitating payment transactions, bringing together financial institutions, businesses, and customers. It acts as an intermediary that authorizes, clears, and settles transactions. Here’s how this actually works:

• Authorization: When a Mastercard is swiped, dipped, or entered online, the transaction details are sent to the business’s bank, then forwarded to the cardholder’s issuing bank for approval. Mastercard’s network is the conduit for this data exchange.

• Clearing: Post-authorization, the issuing bank transfers the funds to the acquiring bank through the Mastercard network, and the transaction details are recorded and reconciled.

• Settlement: Finally, funds are deposited from the acquiring bank into the business’s bank account. This usually occurs within a couple of business days.

Mastercard primarily makes money through fees charged to financial institutions for the use of its branded cards and network. Additionally, it charges for other services such as data processing and cross-border transactions, and these fees can vary depending on the jurisdiction and specific services used.

Mastercard’s role in transaction processing demonstrates its broad influence within the global financial system. And with ongoing advancements in payment technology, Mastercard continues to adapt.

Business benefits of accepting Mastercard

Accepting Mastercard offers customer-facing businesses multiple advantages that can directly impact customer experience and the efficiency of financial operations. As one of the most recognized payment networks, Mastercard allows businesses to access a widespread customer base that trusts this form of payment. And B2B businesses in most industries are also highly likely to benefit from accepting this leading international card network.

Here are a few highlights that illustrate how businesses benefit from accepting Mastercard:

• Global reach
  Mastercard is accepted in over 210 countries and territories, which means accepting Mastercard gives businesses instant international relevance and market access.

• Speed and convenience
  Transactions are quick, usually requiring only a tap or swipe, which makes this card network an easy choice for businesses that want to provide a low-friction payment experience for customers and increase the efficiency of their checkout operations.

• Security features
  Mastercard uses sophisticated security measures—such as tokenization and biometric authentication—to safeguard transactions, reducing the risk of fraud.

• Data analytics
  Mastercard offers businesses access to valuable insights through data analytics, enabling them to make informed decisions on inventory management, pricing strategies, and more.

• Flexible payment options
  With Mastercard, businesses can offer various payment solutions—including contactless payments, mobile transactions, and ecommerce capabilities—to accommodate a diverse range of customer preferences.

These advantages make it easier for businesses to adapt to market changes, meet evolving customer expectations, and preserve trust with customers, partners, and vendors.

Mastercard security measures

Mastercard takes a multifaceted approach to maintaining transaction safety across its global network. Like other global payment networks, it continually adapts and improves its security mechanisms. The company commits significant resources to maintaining a reputable, resilient security strategy amid the complexities of global payment processing.

By investing in protecting its own brand reputation, Mastercard passes along the benefit of strong security standards to the businesses and customers using its products. Here’s a quick overview of Mastercard’s approach to security:

• Advanced encryption
  Mastercard uses state-of-the-art encryption technologies that go beyond standard Secure Sockets Layer (SSL)/Transport Layer Security (TLS) protocols. It applies specific encryption methods to data at rest and data in transit, minimizing exposure and risks at various touchpoints.

• Tokenization
  Tokenization in Mastercard’s ecosystem doesn’t just substitute card data—it often combines it with transactional history and behavioral data to create a multifaceted token, making unauthorized access more challenging.

• Authentication
  Multifactor authentication is commonly employed in financial transactions—especially for those with higher value. But Mastercard doesn’t limit its multifactor authentication to SMS-based codes. It also uses application-based and hardware-based authenticators, such as security tokens, which offer more protection against phishing attempts.

• Biometric support
  Beyond facial and fingerprint recognition, Mastercard is investigating other biometric measures—such as voice recognition and behavioral patterns—to authenticate customers.

• Regulatory adaptability
  Mastercard complies with international regulations, including the EU’s Second Payments Services Directive (PSD2) and the Payment Card Industry Data Security Standard (PCI DSS) in the US. It also adapts to local laws and standards in countries such as Singapore and Australia. These regulations often dictate the level of encryption and data storage methodologies that card networks and businesses need to use.

• Sector-specific scrutiny
  Businesses in high-risk categories, such as those handling controlled substances, may be subject to additional security protocols. This could involve heightened transaction scrutiny or compulsory use of more complex security measures.

• Customized security
  Mastercard offers a range of cards and payment solutions that come with security features tailored to specific needs. Corporate cards, for instance, may include more elaborate spending controls and real-time alert systems.

• EMV chips
  For physical cards, EMV chips are more secure than traditional magnetic stripes. The chip generates a unique code for each transaction, making it difficult to replicate or skim information.

• Artificial intelligence
  Machine learning algorithms scan transactions in real time to assess their risk level and find suspicious activities. Mastercard bases its algorithms on large, diverse data sets that adapt over time and continuously improve the detection of suspicious activities.

• Mastercard identity check
  Also known as Mastercard SecureCode, this is a private code that provides an added layer of security for online shopping. It’s similar to a PIN, but it’s used for online purchases.

• Geographic and sectoral variations
  The level of security might differ based on location or business sector. For instance, in regions with higher rates of fraud, additional security measures such as dynamic authentication may be mandatory. Similarly, high-risk business sectors may be required to undergo additional identity checks.

• Zero liability
  Mastercard offers zero liability protection, meaning cardholders won’t be held responsible for unauthorized transactions, provided they have taken reasonable care to protect their card details.

Requirements for businesses that accept Mastercard payments

If your business is already set up to accept credit and debit card payments, it can probably accept Mastercard payments. Mastercard is one of the major card networks in the US and around the world, so most payment processing providers have software and hardware equipped to accept it.

The exact process of getting set up to accept Mastercard payments will vary depending on how you plan to process transactions (in person, online, etc.), where you’re located, and who your payment processing provider is. But the process more or less looks like this, in most cases:

• Merchant account
  A merchant account is a specialized bank account that businesses need in order to accept credit and debit card payments. However, if you accept payments using Stripe, you don’t need to open a merchant account since Stripe provides that functionality.

• Payment processor
  Choose a payment processor that’s compatible with Mastercard. This processor will handle the technical aspects of the transaction. Again, most payment processors are compatible with Mastercard and other leading card networks.

• Terminal and software
  Businesses need hardware for card swiping or dipping, as well as software for online transactions. Payment processors often provide both, but businesses can also purchase their own as long as they are compliant with Mastercard’s specifications.

• Compliance checks
  Mastercard requires that businesses adhere to PCI DSS, which is a set of compliance requirements for businesses accepting card payments. Regular audits might be required based on the volume of transactions.

• Legal documentation
  Contracts and agreements outlining terms and conditions, fee structures, and other liabilities should be completed with the payment processor or acquiring bank.

• Account setup
  After fulfilling all the technical and regulatory requirements, the business can set up its merchant account to start accepting payments. This involves verifying bank details and testing the payment system to ensure it operates correctly.

• Mastercard branding
  Displaying Mastercard decals and signage at physical locations and digital touchpoints indicates to customers that Mastercard payments are accepted. This is not usually a requirement, but it is an option.

Alternatives to Mastercard

Mastercard is just one option among a variety of global payment solutions accessible to both businesses and customers. The choice of payment network can depend on location, transaction types, and associated fees, among other factors. For those operating or residing in the US, several other major card networks offer distinct advantages:

• Visa: As a chief competitor to Mastercard, Visa has a comparable global reach and offers a range of benefits. It also provides specialized services for businesses, including data analytics.

• American Express: This network is not as widely accepted as Mastercard or Visa, but it compensates with a range of perks, such as strong rewards programs and purchase protection.

• Discover: Primarily used in the US, Discover distinguishes itself with strong customer service and often has lower fees compared to other networks.

There are many other payment methods globally—such as local bank networks, digital wallets, and even cryptocurrency options—that are alternatives to Mastercard.
