Until recently, paying a bill at a restaurant was a stressful experience: you didn't have enough cash, the establishment didn't accept digital payments, or you simply forgot your wallet at home. And when digital transfers first appeared, payments between different banks seemed to take forever; they took up to eight business hours, and if the transfer was made on the weekend, the time could be extended to 48 hours.
To solve this, Colombia began to implement institutional strategies that promoted a fast and secure instant payment ecosystem. But before that, Redeban and Pragma took a proactive approach that is now considered a model to follow.
In 2023, the Central Bank of Colombia announced a new immediate payment system (SPI, in Spanish) that promised to revolutionize transfers in Colombia by 2025. This new instant payment system promised to enable long-awaited banking interoperability, speeding up everyday transfers and offering benefits such as zero transaction costs and strengthening financial inclusion for the unbanked through fintechs or solutions such as digital wallets.
Most of the financial sector prepared to adapt. Redeban, the country's leading electronic payment processor, decided not to wait. Instead of reacting, they chose to lead. They asked themselves: why wait for the future if we could start building it today? This is how "Mis Llaves" was born as a project that, in alliance with Pragma, not only anticipated the norm but redefined collaboration in the Colombian financial ecosystem.
Redeban was already a giant, processing more than half of the country's electronic transactions. However, their vision was to democratize financial services and build the country through innovation.
The announcement of the SPI with the Bre-B seal represented a crossroads. They could wait for the rules of the game, or they could create a market dynamic that facilitated its adoption. The challenge was about uniting competitors for a common good and accustoming millions of users to a new way of interacting with their money.
Thus, in January 2025, long before the regulatory deadline, they launched "Mis Llaves." They did it hand-in-hand with the country's largest financial players: Bancolombia, Davivienda, Daviplata, and Nequi (which together represent 80% of the market), developing an entire ecosystem of banking interoperability that became a tangible reality for Colombians.
Something was clear: the solution had to be robust, scalable, and, above all, incredibly fast. At Pragma, we understood that architecture wasn’t an end but the means to generate trust.
We built a 100% native AWS cloud solution utilizing a serverless architecture, which allowed us agility and efficiency. The heart of the system is a service orchestrator that validates each transaction in real time.
This architecture met the technical requirements and was designed to support massive growth from day one, guaranteeing 99.99% availability.
"Mis Llaves" went into production in January 2025, and the impact was immediate and resounding. The numbers not only exceeded expectations but showed that the market was more than ready for this change:
Stability was impeccable, but the greatest achievement was human. Millions of Colombians began to familiarize themselves with the dynamics of immediate payments, eliminating friction in their daily lives and generating real financial inclusion.
Redeban and Pragma's proactivity in developing this solution not only made them pioneers in instant payments in Colombia, but also catapulted social, economic, and legal advances within the Colombian market.
"Mis Llaves" is proof that vision and proactivity can transform an industry. Through “Mis Llaves”, Redeban and Pragma educated the market, fostered collaboration, and positioned themselves as true innovators.
This project reminds us that true transformation consists in understanding the human needs and using technology to build bridges and improve people's lives.
