LëtzTap

LëtzTap Payment System

About this app

LetzTap turns your smartphone into a powerful event POS system. Go cashless at festivals, fairs, club events, and any gathering with NFC card-based payments.

HOW IT WORKS
Guests receive an NFC card at your event. They top up their balance with cash, card, or Payconiq — then simply tap to pay at any booth or bar. Fast, secure, and no cash handling needed.

FOR EVENT STAFF
• Top Up — Load balance onto NFC cards via cash, Stripe card payment, or Payconiq QR code
• Sell — Process purchases by NFC tap, cash, card, or Payconiq
• Split Payments — Divide a purchase across multiple NFC cards
• Card Info — Check any card's balance and transaction history
• Card Return — Refund remaining balance and deposit at the end
• Receipt Printing — Print receipts via Sunmi cloud printers

FOR GUESTS
• Scan your NFC card to check your balance anytime — no login required
• Top up your card directly from your phone via card payment or Payconiq
• View your recent transactions

PAYMENT OPTIONS
• NFC card tap-to-pay
• Cash
• Stripe Terminal (Bluetooth readers & Tap to Pay on Phone)
• Payconiq QR code payments

BUILT FOR ORGANIZATIONS
Multi-tenant system with role-based access. Admins manage events, products, categories, and team members. Each organization is fully isolated with its own data and settings.

SECURITY
• All NFC card data is cryptographically secured (HMAC + SHA-256)
• Card balances stored server-side — no data on the card itself
• End-to-end encrypted connections
• Stripe-certified payment processing

LetzTap is built for clubs, associations, and event organizers in Luxembourg and beyond who want a modern, cashless payment experience for their events.
