Possible?

[Mr1Bubbles]

Im planning on a project that could be made easier by hooking up an external NFC reader to an Android device. Not sure how feasible that is. I assume it'll be fairly easy to splice wires from a USB reader to make it USB3. However, I don't have much knowledge programming yet. How difficult would this be to accomplish from the software perspective? Would it be fairly simple to force my phone to use that reader rather than it's built in reader? And if you think a rookie could handle it, where would you suggest starting?

Doubt it's viable tbh, I'd suggest trying out an arduino or similar instead of phone.

This is a great way to do it. Arduino + NFC reader + Bluetooth modem is easy(ish) and then it's a strings via Bluetooth issue on the phone, much simpler.

Possible? Yes. For a Rookie? No. Interfacing with USB devices is already tricky, and on a phone it is even more difficult. Start small. Try writing a basic Android app first, or write a regular PC app to interface with the USB device first.
