Thanks to the proliferation of Square card readers & POS terminals, signing for purchases on iPads and email receipts are the norm in Brooklyn. And I dig it, because the digital pads & stylii at the grocery store / CVS are awful.
I also like how I can scan a copy of your signature in Preview on OSX and use that to e-sign documents. That’s how I signed all my coop application forms.
Signature Pad uses HTML Canvas and some spline interpolation magic from Square to create a very fluid signature pad. The best part? you can save / export your signature as a base64 encoded PNG for later use.
