The act of using your finger instead of a pen to sign for a credit card transaction on a device like an iPad.
This guy comes into my shop, and instead of using his finger to sign for his purchase, the idiot whips out a sharpie and signs the iPad! Now it's all fucking stained and shit! So I now hide all pens and tell people I need their fingature.

Writing your signature on a trackpad with your finger.
My fingature looks nothing like my real signature.
