signoCapture - Use your iPhone or iPad to capture signatures. ** Functions ** - Sign documents on your PC using your iPhone or iPad. - Capture high-quality biometric signatures*. - Support for the Apple Pencil for a particularly high resolution signature. - Sign PDF documents according to ISO and eIDAS standards. - Highest security: Benefit from modern signature and encryption methods. ** Description ** In combination with the desktop software signotec signoSign/2 or the signotec signoAPI for Windows you can easily use your iPhone or iPad to sign PDF documents electronically. All you need is this free app "signoCapture" and a compatible Windows software, such as signotec signoSign/2. The document to be signed is displayed on the computer. When signing, the iPhone or iPad is connected to capture the signature. Not only the graphic but also biometric data (e.g. pressure, speed, time, etc.) is captured in the best possible quality* and stored in the document in RSA-encrypted form and irrevocably linked to it. This allows you to reliably check for post-signature tampering and identify the signatory in the event of a dispute. The connection between the computer and your iPhone or iPad is established using Apple Bonjour. The setup is very simple: Just connect your devices via a hotspot and start the signature process. The available device is displayed to you and linked once via a pairing code. You can then capture any signatures via your mobile device. The solution works completely offline and does not require any internet or server connection. *The quality and resolution of the signature is determined by the hardware. For the highest possible resolution, we recommend using the Apple Pencil.
