Banking as a Service (BaaS): How Evolve Open Banking Works

Open banking enables third-party financial organizations to provide consumer or business transactions, banking, payments, credit, and other financial banking services.

This is done using modern, best-in-class technology such as APIs or application programming interfaces. The purpose of open banking is sharing bank-like functionality with financial technology (fintech) and non- financial companies so that experiences can be tailored to fit the diverse needs of end users. At Evolve Open Banking, we offer a secure banking as a service (BaaS) environment, which connects end users to platforms and third parties while complying with banking regulations.

Open Banking with Evolve

Open banking has gained popularity because it can increase the speed and efficiency of financial transactions and enables a variety of applications to organize and manage finances in new and engaging ways for end users.

Open Banking relies on APIs (application programming interfaces) that let authorized third-party providers connect their software to bank systems to support account access, payments, and other services. In practice, an end user provides customer consent for a specific app or platform to access specific data or initiate specific actions, and those permissions govern what the third party can do and what the bank will share.

Open Banking and BaaS are related. BaaS drills down further into the concept of Open Banking. BaaS is the products financial institutions offer to non-financial and financial companies to enable banking services. BaaS solutions allow the third-party company to access the functionality of the bank.

For this reason, open banking can solve many problems for consumers and businesses. The security of the digital economy in open banking addresses the issue of lack of trust in banks. It also can increase the speed to market of fintech businesses.

Card issuance is one component of a modern approach to financial management within Open Banking. Evolve’s Card issuance solution creates, issues, and manages credit and debit cards. These cards can either be completely digital or also have a physical card component.

A benefit of issuing a virtual-only card is the ability to prevent fraudulent transactions via dynamic card number provisioning (a feature that can generate or rotate card details for specific transactions) or other digital fraud prevention features.

Open Banking vs. BaaS

Open banking vs. BaaS comes down to what you’re trying to deliver: Open Banking focuses on authorized data access and certain API-enabled actions, while BaaS focuses on delivering regulated banking products and infrastructure through a bank partner. Embedded finance often uses BaaS to place those financial capabilities directly inside your existing app or website. Choose Open Banking when you primarily need permissioned access to accounts and transactions to power experiences like personal finance insights, verification, or payments. Choose BaaS when you want to offer banking products (like accounts or cards) under your brand without becoming a bank. Choose embedded finance when you want financial features to live inside a non-financial product journey, such as checkout, invoicing, or loyalty.

Our BaaS Environment

All financial services are maintained by a secured environment. As a BaaS provider, we guide our customers through the steps of creating their own secured financial environment to support various use cases.

Our solutions are designed to be flexible, so they can be tailored to solving the financial needs of your end users.

BaaS vs Open Banking

The Difference Between Open Banking, Embedded Finance, and Banking as a Service (BaaS)

Open Banking allows banks to host accounts and provide transaction methods for financial and non-financial businesses to embed into mobile applications. Banks provide a suite of Banking as a Service (BaaS) products using technology like APIs. These technologies enable the capability for other organizations to embed financial functionality into other products and services

Let’s look at all three in more detail.

Open Banking uses technology like APIs to offer non-financial and financial businesses a network of financial products like accounts and transaction methods. This means third-party providers are allowed access to payment products so they can design and build new user experiences. From the bank perspective, Open Banking is like extending their banking charter to other companies.

An example of Open Banking would be a personal finance app enabled by banking technology that lets customers view insights into their monthly spending online.

Embedded finance is the concept of taking BaaS solutions and embedding them into a non-financial business’ mobile application or website. With embedded finance, any business could have a financial component incorporated into its business.

For example, a department store would like to issue a branded credit card for their store with different features, rewards, and perks. The department store can partner with a bank to issue the card and obtain end users without becoming a financial institution themselves. The department store would still be heavily involved in compliance and regulatory obligations, but the banking piece is managed by the bank.

The concept of embedded finance can create a personalized financial experience for dedicated end-user bases of existing businesses that adds value to the customer.

BaaS is a component of Open Banking. BaaS is the products financial institutions offer to non-financial and financial companies to enable banking services. It facilitates bank functionality supported by the infrastructure provided by the licensed bank’s technology layer. Essentially, BaaS ecosystems allow non-banks to offer banking services.

An example of BaaS is a car company offering financing directly through its website in partnership with a traditional bank. It can provide all the necessary services under its own brand while maintaining compliance with banking regulations and without the burden of registering and maintaining its own financial institution charter.

When you partner with a chartered bank like Evolve Bank & Trust, you’re building on a regulated banking foundation that can support compliant account, payment, and card programs. Evolve is a Member FDIC, and we’re a principal member of both Mastercard and Visa, which can matter when your product requires card-network access and bank-backed program oversight.

Open Banking and BaaS programs come with shared responsibilities across compliance obligations, data security, and third-party dependency. You’ll want clear controls for KYC (Know Your Customer), AML (anti-money laundering), data access permissions (including customer consent), and vendor oversight so your program can scale without creating unnecessary risk.

Evolve Bank & Trust supports these partnerships with bank-level risk management expectations, a structured approach to third-party relationships, and security-oriented integration methods that favor authorized API access over credential-based approaches like screen scraping.

BaaS Use Case Examples

There are four main users of BaaS and Open Banking: traditional banks, fintechs, non-fintech companies, and end users. Traditional banks have the necessary licensure to provide core financial services, which allows fintechs and non-fintechs to embed BaaS functionality into their user experiences. Here are some use cases for BaaS.

Online Banking
Fintech firms can provide online banking services to clients via BaaS in addition to offering services that help people track their incoming and outgoing transactions. For modern users, these user-friendly online services might be more convenient and accessible than traditional banking models.
Card Issuing and Acquiring
BaaS also enables issuance of credit, debit and prepaid cards. The bank is the sponsor for these card programs and the fintech or non-fintech can brand and acquire customers for their programs. The cards can be issued virtually or have a plastic component as well. Some examples issued by Evolve include the Dave debit card and the Uber Pro card.
Buy Now, Pay Later
Companies can use BaaS to offer services to customers. An example would be an airline that uses one-click financing to provide smooth digital experiences, guarantee travel plans won’t be disrupted and spread the cost of a booking over time. It also means companies can offer “buy now, pay later” financing.
Neobanking
While it’s possible to set up a website  and mobile application, banking regulations and compliance requirements are rigorous to become a bank in the United States. BaaS solutions let businesses offer banking services like a traditional bank. Financial startups and innovators can set up a neobank without applying for a banking license by partnering with a BaaS bank.

Frequently Asked Questions

What is banking as a service (BaaS)?

Banking as a Service (BaaS) is a model where a licensed bank provides the underlying banking capabilities—like accounts, payments, and card programs—so your business can offer financial features through APIs inside your product.

What is the difference between BaaS and open banking?

Open banking focuses on secure connectivity and data sharing between financial institutions and third parties. BaaS typically goes further by packaging bank capabilities into products you can embed and operate as part of your customer experience.

What is the difference between BaaS and embedded finance?

BaaS is the bank-provided infrastructure and product set. Embedded finance is how a non-financial company places those financial features into its app, website, or customer journey.

Do I need a banking license to offer financial services through BaaS?

You typically don’t need your own banking license to offer financial features through BaaS, because the bank provides the license and regulated banking layer. You still need to meet program requirements and work within compliance expectations set by the bank and applicable regulations.
