ThaiCampus — Student Study-Material Marketplace
A peer-to-peer marketplace where Thai university students buy and sell lecture notes, past exam papers, cramming summaries, and practice exercises — with instant PromptPay checkout and one-click PDF delivery.
Overview
ThaiCampus is a student-only marketplace built around instant Thai payments and signed-URL PDF delivery, designed to let one student turn their notes into income and another get the material seconds after paying.
Key Features
- Student-only access — sellers verify with Student ID and Citizen ID before they can list material
- Instant PromptPay checkout with real-time payment verification — no card gateway sign-up required
- Time-limited signed-URL PDF delivery the moment a payment is confirmed
- Four content tracks: lecture notes, past exams (with solutions), pre-exam summaries, and practice exercises
- Seller payout flow with transparent platform fee — example: ฿119 payout on a ฿149 sale (฿30 fee)
- Thai/English UI toggle and university-scoped browsing
