Tegoed Checker is a free Android app developed by Gemeente Rotterdam under the Business & Productivity category and Finance subcategory. The app aims to provide a quick and easy way for Rotterdam Pass holders to check their AOW credit or Youth credit.

With Tegoed Checker, all you need to do is scan the barcode at the back of your Rotterdam Pass using your phone's camera. The app will then show you how much credit you have left to spend, based on the time of request. You can also view your credit through your My Pass account at rotterdampas.nl/account/inloggen if you don't have a phone with a camera.

Overall, Tegoed Checker is a simple and efficient app that serves its purpose well. It's a convenient way to keep track of your Rotterdam Pass credits and helps you plan your expenses accordingly.
