How to Use Your Handphone to Sign Documents on a Computer

Can you use handphone to sign a document that is open on your computer? Yes. With Remote Signature Pad, your handphone (mobile phone or smartphone) becomes a signature pad. You sign with your finger and the signature is drawn into the signature box on the computer screen.

What can you sign?

You can sign any document where the signature can be drawn with the mouse: a PDF in Adobe Reader, a form in your business or point-of-sale software, or a signature box on a web page. If it can be signed with a mouse, you can use handphone to sign it instead.

How to use handphone to sign, in four steps

1. Install the app on your handphone from Google Play or the App Store. The Lite version is free for one signing session per day.

3. Connect the two by Wi-Fi. Tap IP Network on your handphone, then Auto Connect. Android also offers Bluetooth and USB.
4. Open your document, then sign on your handphone.

Signing on the phone or signing on a tablet?

The phone is the simplest, since you already carry it. If you want a screen that stays at the counter, the Tablet Edition is an Android tablet with a stylus that arrives ready to use.
