Re: Not smart.
Step 1) Talcum powder or similar over the screen, backside of the phone and any other items that are liable to have fingerprints.
Step 2) Sticky tape over now visible fingerprints.
Step 3) Sticky tape on scanner. You now have a digital copy of the fingerprint. Depending on the quality, some touch up may be required.
Step 4) Depending on technology, you can now print the fingerprint to paper (This still fools many fingerprint readers!) Or use 3d printing to make a mold.
Step 5) If you used 3d printing, fill the mold with a suitable gel. It will take a few hours to set. Skip this step if your targeted fingerprint reader can be fooled with printouts.
Step 6) Use fingerprint.
Total cost in equipment for printout fingerprints? A few bucks for the talcum and sticky tape. You probably already have the computer and scanner.
Total cost for the equipment for proper fingerprints is a few thousand bucks for the 3d printer, which is reusable and a few dollars per mold.
Depending on the quality of your mold and gel, you can get fingerprints thin enough to apply to your finger directly, making it difficult for others to notice that you're not using your own prints to log in. This is a moot point for the phone app as you do not need to use it near anybody, you can log in at home and transfer money at will.
