Billfold POS, Event Payment Platform

Finance / Event Technology

The Challenge

Large events and festivals often face long queues and payment delays, negatively affecting attendee experience and vendor sales. Billfold needed a secure and scalable cashless payment system to streamline event transactions across RFID, NFC, QR, and bank cards.

The Vibe Solution

Devsloop helped implement a modern POS platform supporting multiple payment methods, rapid event setup, vendor management tooling, and real time analytics. The system was designed to be highly available, fault tolerant, and easy for event operators to configure for each festival or venue.

The Outcome

The platform served 1.5M+ event attendees, supported over 430+ event nights, and helped drive a 50% increase in average per person sales. Payments became faster and more seamless for attendees and vendors alike, aligning operational efficiency with better on site experiences.
