Is Game Key Card? helps you verify if a Nintendo Switch 2 game is a genuine physical cartridge or a Game Key Card (GKC) — a placeholder that doesn't contain the actual game.

Use the search tool to quickly check any game and see whether it's distributed on a traditional game card, or if it's a GKC, CIAB (Code In A Box), or unknown. You can also filter by region (USA, EUR, JPN, ASIA).

Whether you're a collector, buyer, or preservationist, this app will help you avoid misleading purchases and stay informed.

Features:

* Simple game search
* Advanced filters (region, GKC type)
* Bilingual support (English and Spanish)
* Friendly interface
* Lightweight and fast
* Community-driven updates via form submission
