Jarcas Promo Code System v1.0.1
The Jarcas Promo Code System is a cross-platform solution for creating, managing, and redeeming promo codes for in-app purchases. Perfect for when your game/app provides in-app purchases and you want to give them away to certain people (beta testers, friends/family, reviewers/press, contest winners).
Features:
– Well-documented with full source code
– Works on any platform
– Server-side promo code storage and verification via PHP/mySQL
– Add or remove codes after release without requiring an app update
– Create and manage codes from the Unity Editor interface (no coding or phpMyAdmin necessary)
– Supports multiple games/apps in a single database
– Supports multiple products per game/app
– Highly configurable code generation. You choose exactly how you want your codes to look
– Can remove lookalike characters (“1”, “I”, “0”, “O”, etc.) to avoid user confusion
– Promo codes can be configured to be restorable (useful for non-consumable products)
– Promo codes can be single-use or multi-use
– Tracks device ID on redemption
– Generate many codes in one click
– Provides security against hackers spoofing server messages
– Works in Unity Free
NOTE: Promo codes are stored and verified by a web server. The necessary server-side PHP scripts are included in this package. However, you are required to supply the server itself. Any server providing PHP and mySQL databases will suffice.
