WinStamp - Loyalty Card is a free customer loyalty program developed by WinStamp Oy for Android users. It is a simple, quick, and cheap way for business owners to start their customer loyalty program. The program consists of two apps, one for the business owner (WinStamp Business) and the other for the customers (WinStamp). The business owner can download the WinStamp Business app and customize their stamp card, and the customer can download the WinStamp app and get their unique QR code.

The business owner can then scan the customer's QR code and stamp their card. WinStamp - Loyalty Card offers several features such as a customizable stamp card, a detailed customer list, messaging to customers, and live statistics to track daily, weekly, and monthly stamping numbers. The app is proud of its quick start feature, customer-friendly approach, safe method, and no extra device requirement. Additionally, the app offers a 30-day free trial without any credit card information.
