I am developing app with Aadhaar payment which needs fingerprint authentication using Aadhaar UIDAI. but in market there are lot of fingerprint scanner devices. each device has their own rd service which return scan data(new format PID data). But I need one solution for many devices. I mean i don't want to keep track of multiple RD service APk files with our application. whichever device is there it should return PID data of finger scan for Aadhaar authentication.
Currently i have 3 device secugen, StarTek and Precision
1. Is it possible to install only one RD service for these three devices with application?
2. is it possible to have RD service .aar files in application itself?
3. one more thing can i use device(mobile's) fingerprint scanner for Aadhaar authentication?
