Mantra Fingerprint Data Processing App
Budget: ₹1,500 – ₹12,500 INR
I need an Android application that talks directly to the Mantra MFS fingerprint scanner, captures a user’s fingerprint and immediately runs the required processing logic inside the app itself—no cloud calls, no external storage. The workflow is simple: plug the Mantra device into an Android tablet or phone, prompt the user, grab the biometric template or image that the Mantra SDK exposes, run an in-app routine (for example matching, quality scoring or whatever you wire for now as a placeholder), then surface a success / fail result on screen.
Key points you should know before we start:
• Mantra MFS SDK integration is essential; please be comfortable setting up the device drivers, permissions and sample code on Android 8+.
• All biometric data stays local to the device; nothing is written to disk unless it is encrypted inside the sandbox you create.
• Java or Kotlin in Android Studio is fine—pick whichever you are faster with, just keep the code clean and well-commented so I can extend it later.
Acceptance criteria
1. APK installs on a standard, non-rooted Android phone and recognises the Mantra MFS when connected.
2. Fingerprint capture and on-device processing complete in under five seconds on a mid-range handset.
3. Source code, build instructions and a short README are delivered so I can reproduce the build without guesswork.
If you have shipped something similar, please tell me which device you integrated and how you handled USB permissions; it will speed up our conversation.
