Ever struggled with testing payment QR codes? If you work in banking or fintech, you probably know how challenging QR payment testing can be. You generate an EMVCo QR code, but then you need to validate its structure, check the CRC, test invalid QR data, or encode and decode Consumer QR codes. Sometimes, even a small error in the QR data can cause a payment to fail. Finding that error can take a lot of time. We noticed that these tasks often require different tools. So we thought, why not build one app that can handle them all? That's how AttoQR came to life. At AttoExa Solutions, we built AttoQR to help banking professionals, fintech developers, and QA testers work with QR codes more easily. Here's what you can do with AttoQR: ✅ Generate and Scan QR Codes ✅ Generate EMVCo Merchant & Consumer QR Codes ✅ Validate and Verify QR Data ✅ Generate and Test CRC Values ✅ Create Valid & Invalid QR Codes for UAT ✅ Generate Encryption Keys for Consumer QR Encoding & Decoding No need to switch between different tools for these tasks. You can do it all from your phone. We're happy to share that AttoQR (Beta) is now live on Google Play. This is our first release, and we're looking forward to making it better with feedback from people who actually work with payment systems. If you're working in banking, fintech, digital payments, or software testing, give AttoQR a try. We'd love to hear what you think and what features you'd like us to add next. 📲 Search "AttoQR" on Google Play to download the app. Developed by AttoExa Solutions 🌐 https://attoexasolutions.com/
