关于 扫描签名 的常见问题
Does the signature look genuine on contracts?
Yes. Because it digitizes your real pen strokes, it looks identical to an in-person physical signature on the document.
Can I reuse the scanned signature on multiple documents?
Yes. Once digitized, your signature is saved in your offline signature vault and can be stamped onto any PDF in seconds.
