Reimagining payments with Open Banking: LemmePay for merchants and customers
Description
We partnered with LemmePay, a pioneering Open Banking payment solution, to design and build a web application that enables physical and online merchants to accept instant, secure, low-fee payments, without the need for traditional card terminals. By leveraging QR codes and direct bank transfers, the platform offers a fast, frictionless way for merchants to get paid while giving customers full control over how they pay.
Background
LemmePay was created to disrupt the traditional payments ecosystem by eliminating intermediaries and high fees. Built on Open Banking infrastructure, it allows merchants, whether running a café, barbershop, or ecommerce site, to accept direct bank payments through a simple three-step process: scan, select bank, and approve.
With instant payouts and bank-grade security, LemmePay offers a modern alternative to legacy payment processors. However, to bring this vision to life, they needed a flexible, intuitive web platform that could support merchant onboarding, payment initiation, real-time updates, and data-driven insights, all while staying compliant with financial standards.
Challenge
LemmePay needed to launch a complete payment solution that would:
- Onboard new merchants securely and easily
- Allow customers to scan a QR code and pay directly from their bank
- Replace expensive hardware (like POS terminals) with a mobile-first experience
- Offer dashboards with live payment tracking and analytics
- Maintain regulatory compliance, bank-level security, and user trust
Process
We began with stakeholder workshops to define the product’s user flows, from merchant sign-up and onboarding to payment confirmation and payout tracking. We prioritized ease of use, security, and regulatory compliance from day one.
Our design phase focused on creating an onboarding flow that guided merchants through account creation, identity verification, and business setup without friction. We designed both merchant and customer dashboards, ensuring they were clear, actionable, and mobile-friendly.
The development phase involved close integration with Open Banking APIs, robust error handling, and real-time event streaming to support instant notifications and payment confirmations. We built out critical features such as:
- QR code payment generation for both physical and online use
- Three-step customer journey: scan → verify → approve
- Instant bank-to-bank payments with no intermediaries
- Merchant dashboard with transaction history, payout tracking, and analytics
- Customer dashboard for viewing past payments and receipts
- Secure onboarding and KYC (Know Your Customer) flows
Result
The launch of LemmePay gave merchants a simple, powerful way to accept payments without traditional point-of-sale hardware. With instant settlements and the lowest processing fees in the industry, merchants saw immediate operational savings and faster cash flow.
Customers benefited from a secure, private, and effortless payment experience, no cards, no apps, just a scan and bank approval. Real-time notifications and analytics brought transparency and trust to every transaction.
