A busca por soluções inovadoras nunca foi tão urgente no universo financeiro. As exigências do público por experiências digitais, a necessidade de escalar produtos e a pressão regulatória criam um cenário em que lançar um cartão próprio exige não só agilidade, mas também domínio técnico e segurança. Neste artigo, vamos mostrar como funciona o modelo de emissão de cartões por meio de plataformas de Banking as a Service e como fintechs, bancos digitais, corretoras e até varejistas tradicionais podem criar jornadas de sucesso sem abrir mão do compliance e da boa experiência do cliente.
O que é emissão de cartões via BaaS?
Before discussing the stages and advantages, it is essential to understand the concept. The model of Banking as a Service (BaaS) in card issuance allows companies of all sizes to quickly launch physical or virtual cards without the need to set up their own bank or develop systems from scratch.
The essence lies in integration: technology, operations, and compliance, all orchestrated through APIs. In the BaaS model, fintechs and companies use third-party infrastructure to connect their platforms, create financial products, and issue cards under their own brand, whether for end clients, employees, or business partners.
In the past, issuing a card was a project that took months, if not years. It required dedicated IT solutions, banking partnerships, contracts with card networks, and a legal department attentive to Central Bank regulations. Today, this reality has changed. With BaaS providers like Azify, this entire ecosystem is accessed through smart, plug-and-play integrations.
Full customization of card design and functionalities
Complete management through the application or platform of the company
Control of limits, blocks, notifications, and real-time usage
Support for physical and virtual cards, prepaid, credit, or multi-cards
Embedded compliance, aligned with Central Bank guidelines, PCI DSS, and LGPD
The issuance of cards via BaaS is not limited to fintechs: digital banks, marketplaces, mobility apps, benefits companies, and even retail players already use the model to diversify revenue, create loyalty programs, or simplify internal payments.
At Azify, the proposal takes on another dimension. With robust APIs, built-in compliance, and end-to-end operation, launching a card ceases to be a technical problem and becomes a concrete opportunity for rapid and secure growth.
Como funciona o modelo de Banking as a Service?
The functioning of BaaS for issuing cards can be explained by the combination of three pillars: technology, operation, and regulation. These elements make it possible for non-bank companies to operate with financial products without traditional hurdles.
At the core of BaaS are the APIs, which connect banks, processors, card issuers, and brands to the client's digital environment. This makes it possible, for example, for a mobility app to issue, manage, and deliver cards to its drivers without creating its own financial structure.
All transactions go through the platform's structure, which performs authorization, settlement, and supervision
The embedded back office ensures automatic reconciliations, fraud controls, and support for audits
Compliance rules are configured at the beginning, preventing future problems with regulatory bodies
Integrations are done with simplified documentation and testing environments
The routine can be summarized in clear steps:
Initial setup, choice of the issuance flowchart, and definition of business parameters;
Connection between the company's platform and the BaaS system through secure public APIs;
Request for cards (physical or digital), customized with branding and eligible functionalities;
Sending user information for profile analysis, validation, and automatic compliance;
Generation, activation, shipping, and monitoring of issued cards;
Operational management, with real-time reports, limit monitoring, and transaction reconciliation.
In the article about Banking as a Service by Azify, you will find a direct explanation about the integration architecture, types of APIs, and the advantages of this model compared to traditional banking outsourcing.
The highlight is the experience: for the end customer, the card arrives quickly and ready to use; for the company, the interval between conceptualizing a new product and putting it into practice is much shorter.
Quais as etapas para implementar uma solução de emissão de cartões?
Those who wish to operate the issuance of cards via BaaS need to follow a journey that goes from product design to regular operation. The steps may vary depending on the supplier, but in Azify projects, the typical flow involves:
1. Product design and definition of needs:
the company defines the audience, types of card (credit, debit, prepaid), desired functionalities, required integrations, and differentiators. This is the time to listen to the business and technology teams.
Who will be the user of the card?
What operations does it need to allow?
Will there be limits, cashback, multi-currencies, cryptocurrencies?
A clear plan avoids rework when reaching the integration phase.
2. Selection of the infrastructure provider:
next, a thorough analysis of suppliers is conducted. Factors such as technological solidity, operational capacity, security, customization, and history of relationships with the financial sector will be evaluated. Contents such as the guide to evaluating BaaS providers in Brazil can serve as a roadmap for this.
In the case of Azify, for example, the Azimut group offers global regulatory support and modern APIs, creating a reliable environment from start to finish.
3. API integration and testing
The following phase involves the work of developers. Once the documentation is in hand, integration with APIs begins, which encompass:
Card request and activation;
Balance management, limits, and blocks;
Issuance of statements and real-time notifications;
Connection to CRM and support systems.
Testing environments facilitate approval, ensure that any errors are identified, and allow for simulating the complete cycle.
By bringing technology and business closer together, the go-to-market is accelerated without sacrificing quality.
4. Customization of journeys and security:
issuing a card is not enough. It is essential to define activation flows, unlocking, reissuance, beneficiary registration, and inclusion in digital wallets (Apple Pay, Google Pay, Samsung Pay and others). Customization also includes anti-fraud rules, profile analysis, automatic alerts, and preventive blocking against attempts of suspicious transactions.
5. Continuous operational management:
with the solution in production, the routine involves real-time monitoring, reissuing cards, expanding functionalities, and constant compliance monitoring.
24-hour support,
Compliance with circulars and regulations from the Central Bank and card networks
Data management according to the LGPD
Automated reports for internal audits
The differential of Azify is offering real and consultative support, both from the technical and regulatory points of view, which brings peace of mind in times of incidents or inspections.
Como garantir segurança e compliance regulatório?
The concern with security and compliance is natural when it comes to financial products. The Brazilian regulatory environment is among the most demanding in the world. However, a good BaaS project incorporates these requirements from the start.
In the BaaS model, security is designed by default. Just look at the best practices of the top providers to understand how this happens continuously.
End-to-end data encryption
Anti-DDoS protection on all API endpoints
24/7 incident detection and response systems
Processing within PCI DSS requirements for sensitive data protection
Constant vulnerability testing
Automatic updates to keep the platform always compliant with the manuals of payment networks and the Central Bank
Compliance by Design Solutions
The term "compliance by design" refers to the idea that all steps, from registration to the settlement of a purchase, should be prepared to meet local and international regulations.
Automated procedures for KYC (Know Your Customer)
Active monitoring of suspicious transactions (AML)
Ongoing audit with intelligent reports
This approach is detailed in the article compliance in BaaS, which shows how new technologies enhance data protection and the transparency of financial operations.
Responsible Data Management
Data travels through the BaaS infrastructure with modern protocols and different layers of security. There is limited permission by profile, auditable logs, and processes for anonymizing sensitive data according to the LGPD. This means that customer information is protected and used only for authorized purposes, with complete traceability.
Constant Audits and Updates
Robust BaaS platforms undergo regular audits, conducted by both national and international entities, to ensure compliance with rules such as PCI DSS, SOC 2, various ISOs, as well as resolutions from the Central Bank. These audits are not just bureaucracy; they serve to quickly detect and correct vulnerabilities before they reach the end user.
The update process is continuous. Regulatory changes are closely monitored and quickly reflected in adjustments to the API, the fraud prevention system, and governance policies. On our blog, the content about BaaS APIs shows how integrations are not only secure but also adaptable to new legal and technological requirements. Compliance is not built after the fact; it is born alongside the product.
In conclusion, the era of financial services is changing. The Banking as a Service model democratizes access, accelerates time to market, ensures personalization, and above all, maintains full adherence to regulations.
Azify stands out as a protagonist in this transformation, offering pluggable APIs, complete back-office, real-time monitoring, and robust regulatory support. The result? Modern, scalable, and secure experiences, no matter the size or segment.
