As payment technology evolves, ISVs must choose between SDKs or cloud-based APIs like Payroc Cloud when integrating card-present payments. This decision significantly impacts development time, scalability, security, and ongoing maintenance. In this guide, we explore both integration methods, providing insights to help ISVs make informed decisions that align with their business goals and technical requirements.
SDK Integration: Deep Control Over Transactions and Payment Hardware
SDKs offer ISVs deep control over the transaction process by integrating payment devices directly with software. This allows for tailored payment experiences to meet specific industry needs. However, it requires managing hardware compatibility, transaction flows, and, in some cases, PCI compliance.
With SDKs, ISVs have full jurisdiction over payment hardware, enabling seamless integration with various systems. This flexibility is valuable across many industries but demands active maintenance of firmware and device configurations. Outdated devices can lead to system failures and interrupted transactions, impacting customer satisfaction, operational efficiency and ultimately revenue. Regular updates ensure smooth, reliable transactions and prevent disruptions.
Outdated payment devices disrupt operations. Over 50% of shoppers report technical issues at checkout due to outdated systems, leading to slow transactions and poor customer experiences (Ingenico). Regular updates are essential for ISVs to maintain reliable payment processing.
SDK Integration: PCI Compliance, Offline Transactions and Data Security
SDK integrations also require compliance considerations. If ISVs handle PCI compliance internally—especially without scope-reducing technologies like Point-to-Point Encryption (P2PE) or End-to-End Encryption (E2E)—they must secure payment data across their system and meet validation standards.
SDKs can also support offline transactions, allowing payments without real-time connectivity. While this is useful for industries like transportation or large events, it increases the responsibility to safeguard stored data until it’s authorized. Strong security measures are crucial for maintaining compliance and preventing breaches.
SDKs also enable ISVs to capture and store various types of Personally Identifiable Information (PII), including sensitive data like cardholder names and account numbers. This flexibility allows for personalized services but comes with significant responsibilities for data protection. ISVs must ensure compliance with industry standards like PCI DSS and privacy regulations to avoid breaches and penalties.
While SDKs offer precision and customization, they require greater development effort, longer certification times, and ongoing maintenance, which can complicate scalability. Despite these challenges, SDKs remain a powerful tool for ISVs needing tailored solutions.
Even with SDKs, ISVs should implement scope- reducing technologies like P2PE or E2E to minimize risk. In 2024, the average cost of a data breach reached $5.17 million (IBM).
Electric Era increased station uptime by 0.5%, resulting in two additional days of operation per year by supporting offline transactions with Payroc’s payment solutions. This enhancement ensures continuous service and customer satisfaction.
Cloud APIs: Scalable, Flexible, and Device-Agnostic
Cloud APIs offer an alternative to SDKs by simplifying payment integration and minimizing the need for device- specific certifications. The cloud provider handles device management, transaction flow, and compliance, allowing ISVs to focus on growth and innovation.
With a cloud-based API, ISVs no longer need to manage payment devices or control transaction workflows locally. The API handles the entire process, including device interactions, transaction management, and updates, ensuring a smooth and efficient experience.
Cloud APIs also simplify PCI compliance by securely managing sensitive data, often removing the ISV’s software from the compliance scope. This reduces the burden of maintaining compliance standards, allowing ISVs to focus on business growth while minimizing risk.
ISVs can integrate with cloud APIs to access supported devices. As new devices are added, they become automatically available, eliminating the need for additional development. This allows ISVs to quickly adopt new technologies and scale their offerings, while the cloud handles device updates and compliance complexities.

Cloud APIs: Scalable, Flexible, and Device-Agnostic
Scalability is a major advantage of cloud APIs. New devices are seamlessly available without major reconfiguration, allowing ISVs to scale quickly while minimizing technical debt and maintenance. As devices and features are introduced, they become automatically available through the API, requiring no additional development.
Another key benefit is reliability. Cloud APIs monitor
and resolve communication issues between devices and software. For example, Payroc Cloud automatically corrects or reverses transactions during disruptions, ensuring uninterrupted operations. Backup options, such as SIM card support, further guarantee continuous service.
Cloud APIs are ideal for ISVs prioritizing scalability, flexibility, and reduced development effort. They simplify payment integration while reducing technical burdens, allowing ISVs to focus on growth and innovation.
More than 54% of operational failures result in at least $100,000 in losses. Cloud APIs like Payroc Cloud ensure 99.999+% uptime, with features like automatic error correction and SIM card backups. (Uptime Institute)
