TickTap — Trustable Touchless Travel Card
Linking Islands for Samoa. One tap at a time.
Part One: The Context
Project "Island Link"
Zero-barrier, fully-offline, high-trust payment network built for Samoa.
The "Last Mile" Payment Challenge
Infrastructure Gap
Expensive POS can't reach street vendors & markets
Network Anxiety
Tourists avoid roaming; local coverage has dead zones
Trust Gap
No taxi meters; verbal pricing leaves no proof
Part Two: The Solution
Offline First Architecture
Never Offline
Transactions complete locally—even if the whole island loses connection
Zero Hardware Dependancy
Merchants need only an old Android phone—no POS required
Tourist Friendly
One card travels the entire island—no app needed
Hardware Core: NFC Security Card
Military-Grade Security
The advanced NFC chip generates dynamic encryption keys per tap
Zero Power Required
Simple as a transit card—works for everyone
Security of a Bank, Cost of a Sticker
AES-128 Encryption Engine
  • The NTAG 424 DNA is not a simple sticker; it's a cryptographic computer
  • SUN Message (Secure Unique NFC): Every tap generates a unique, one-time-use encrypted URL
  • Result: Impossible to clone (Anti-Cloning) and impossible to reuse old data (Anti-Replay)
Comparison: Why not traditional Visa/Mastercard (EMV)?
  • EMV Cards: Require expensive POS terminals ($300+) and complex Java Card OS. Overkill for micro-payments
  • NTAG 424: readable by any smartphone. No POS hardware required. Perfect for widespread adoption in developing regions
The Economic Breakthrough (Cost Structure)
  • Card Cost: NTAG ($0.50) vs. EMV ($2.00+)
  • Terminal Cost: Zero (Uses existing Merchant Phones) vs. POS ($300+)
  • Maintenance: No battery, 10-year data retention, waterproof
NTAG Chip: Dynamic Key Generation
Cost Scale: POS Terminal vs. Smartphone
Security Standard: CC EAL4 Certified
The Gold Standard
The NTAG 424 DNA is certified to Common Criteria EAL4. This is the same security level used in many Corporate Access Cards and Electronic ID systems.
The Sweet Spot (Comparison)
Magnetic Stripe (Level 0)
Unsafe, easily cloned
EMV Banking Chip (EAL5+)
Extremely secure but expensive and requires heavy infrastructure
NTAG 424 DNA (EAL4)
The perfect balance. It brings AES-128 crypto security to a low-cost sticker, eliminating the cloning risks of older cards without the high cost of banking chips
Why it wins for Samoa
We don't need to defend against "Nation-State" laser attacks (which EAL5+ does); we need to stop cloning and replay attacks. EAL4 does this perfectly at 1/5th the cost.
Part Three: Experience Revolution
The Trust Crisis
When a tourist hails a taxi on a beach with no network, how do you build trust?
