A2A Payments for POS: Benefits, Challenges, and Card Competition

Almost out of the buzzword stage, account-to-account (A2A) payments are now a formidable contender, particularly in the point-of-sale (POS) systems market. A2A payments offer a streamlined and efficient alternative to traditional card payments, coming with a host of benefits and brand-new challenges.

In this article, I will outline the current state of A2A payments, explain how they function within POS devices, and argue why they are here to stay, despite the competition with card payments within the POS ecosystem.

What A2A payments are

Account-to-account (A2A) payments, also known as bank transfers, are a direct transfer of funds between two bank accounts without the involvement of intermediaries such as card networks or payment processors.

  • These transactions are typically facilitated through online banking platforms or mobile banking applications, providing users with a convenient and secure method of transferring funds.
  • Unlike traditional card payments (using physical cards + complex networks for authorization and processing,) A2A payments streamline the transaction process by directly linking the payer and payee's bank accounts.
  • The essence of A2A payments lies in their simplicity and efficiency, allowing individuals and businesses to transfer funds seamlessly without third-party intermediaries. 

A2A payments use the existing banking infrastructure and digital channels as rails for your funds to go through quickly and securely.

How A2A payments for POS devices work

Let’s zoom in on the transaction process.

1. The process begins when a customer purchases using an A2A payment option at a POS terminal.

2. Upon selecting this option, the terminal prompts the customer to initiate a bank transfer from their bank account to the merchant's designated bank account.

3. The transaction is authenticated through secure banking channels, often employing methods such as two-factor authentication or biometric verification, to ensure the integrity and security of the transaction.

4. Once the transfer is authorized and confirmed, the funds are transferred directly from the customer's account to the merchant's account, seamlessly completing the transaction in real time. Simple as.

The benefits: Why A2A payments will last

A2A payments for POS devices have quite a number of advantages up their sleeve that enhance their endurance and attractiveness within the financial landscape. The following benefits solidify the position of A2A payments:

1. Dropping intermediaries: A2A payments bypass intermediaries like card networks and acquirers, reducing merchant transaction costs and expediting settlement times. This direct transfer approach streamlines the payment process, enhancing efficiency and reducing operational overhead.

2. Enhanced security measures: By eliminating the reliance on physical cards and central intermediaries, A2A payments offer heightened security, safeguarding the interests of both merchants and customers. Solutions like kevin. explore the security aspect, enhancing the ability of A2A payments to mitigate the risks associated with fraud and chargebacks prevalent in card transactions. 

3. Seamless integration with banking infrastructure: The seamless integration of A2A payments with existing banking infrastructure offers a familiar and intuitive payment experience for customers who enjoy the benefits of online banking. This interoperability facilitates smooth transactions and fosters customer trust and adoption. 

4. Convenience and familiarity: A2A payments have already earned their reputation as a familiar and convenient payment option among online banking practices. With the ubiquity of digital banking platforms, A2A payments resonate with modern consumer preferences and gain growing popularity. 

For instance, in December 2023, the abovementioned kevin. received a partnership opportunity from Switchio, a digital payment processing platform provider. As a result of the collaboration, kevin. A2A solution will be available on all POS (point-of-sale) terminals connected to the Switchio platform.

Another example is The solution allows merchants to accept A2A payments from customers through a branded app or credit management dashboard. Also, using’s solution, merchants can process payment requests via email or WhatsApp through a branded webpage.
Judging by these arguments, it is no wonder that McKinsey predicts that by 2027, remote consumer purchases at the POS, excluding bill payments, could reach a volume beyond $200 billion. That means roughly 5% share of US digital commerce spend.

Room for improvement in A2A

The benefits of A2A payments for POS devices come with specific challenges. Drawing insights from industry experts, let's explore key areas for enhancement in A2A payments.

  • Widespread adoption and interoperability. McKinsey identifies the need for widespread adoption and interoperability among banking systems as a significant challenge for A2A payments. To address this issue, collaborative efforts are needed to establish standardized protocols and frameworks that facilitate seamless A2A transactions across diverse banking networks and geographical regions.
  • Data privacy and security concerns. Data breaches and unauthorized access are still a threat with A2A payments, even despite their robust security framework. These concerns regarding data privacy and security are potential barriers to the widespread adoption of A2A payments, as Motivate.VC underscores. Implementing robust encryption and authentication mechanisms is imperative to building customer confidence and mitigating apprehensions related to data breaches and unauthorized access.
  • Optimization of UX. The user experience and interface of the existing A2A payment solutions on POS devices can be made better. User-friendly interfaces, intuitive navigation, and seamless integration with existing POS systems are essential to enhancing usability and driving merchant and customer adoption.
  • Transaction speed and reliability. Switchio highlights the need to improve transaction speed and reliability in A2A payments. The steps to enhancing the efficiency and reliability of A2A payments for POS devices include reinforcing the infrastructure supporting A2A transactions, reducing processing times, and minimizing transaction failures are essential steps to enhance.

Addressing these areas of improvement could bring long-term results through collaborative industry initiatives and technological innovation.

A2A vs. Card payments

Several vital distinctions and considerations emerge when evaluating A2A payments against traditional card payments. Each has its own set of implications for merchants and consumers.

1. A2A payments typically boast lower transaction fees and faster settlement times than card payments. These advantages can appeal to merchants who want to optimize their payment processing costs and improve cash flow management. In contrast, card payments may entail higher processing fees and longer settlement periods, impacting merchants' bottom line and liquidity.

2. One notable advantage of A2A payments over card payments is their enhanced control and transparency over transactions. By bypassing intermediaries and directly linking the payer and payee's bank accounts, A2A payments provide a clear and direct exchange of funds. McKinsey highlights this aspect, emphasizing the potential for reduced fraud and enhanced security in A2A transactions. In contrast, card payments involve multiple intermediaries, including card networks and acquirers, which may introduce complexities and opacity into the transaction process.

3. While A2A payments offer compelling advantages in terms of cost and transparency, card payments maintain a significant edge in terms of convenience and ubiquity. Card payments are widely accepted by merchants and supported by established card networks and infrastructure, making them a preferred choice for consumers seeking seamless and hassle-free transactions. Additionally, card payments offer greater flexibility and versatility, allowing consumers to easily make purchases online, in-store, and across international borders.

4. Card payments may also offer additional benefits and incentives that further incentivize consumer usage. Rewards points, cashback, and consumer protections are commonly associated with card payments. These incentives can influence consumer behavior and preferences, leading them to favor card payments over A2A transfers. That’s particularly true in scenarios where the added perks outweigh the advantages of A2A transactions.

Does the world need A2A POS solutions?

A2A payments for POS devices are a disruptive force in the financial industry, offering a direct and efficient alternative to traditional card payments. While A2A payments provide numerous benefits, such as lower transaction fees, faster settlement times, and enhanced security, they also face limited adoption and interoperability, as well as concerns regarding data privacy and user experience. 

As technology evolves and consumer preferences shift towards digital banking solutions, the future of A2A payments for POS devices appears promising. However, this optimistic vision depends on industry stakeholders addressing existing challenges and continuing to innovate to meet the evolving needs of merchants and customers.
