Digital signatures have revolutionized the way we sign documents electronically, and with the rise of smartphones, it's now easier than ever to sign documents on the go.
Most modern smartphones come equipped with a digital signature feature that allows users to create and store their own unique digital signatures.
Digital signatures are legally binding and can be used to sign documents, contracts, and agreements with the same authority as a traditional handwritten signature.
To get started with digital signatures on your phone, you'll need to download a digital signature app, such as Adobe Sign or DocuSign, which can be found in the app store.

What Is
A mobile phone signature is a digital signature that serves as an electronic version of a handwritten signature.
It guarantees the authenticity and integrity of the signed documents, making it a secure way to sign electronic documents.
A mobile phone signature is based on cryptographic procedures that ensure the person signing can be clearly identified and that the signed document cannot be changed without being noticed after it has been signed.
To use a mobile phone signature, a special signature certificate is required, which is issued by a certified trust service provider.

Benefits and Legality
Digital signatures on phones are a game-changer for businesses and individuals alike. They're legally binding in the US and EU, thanks to the Uniform Electronic Transactions Act (UETA) and the eIDAS Regulation.
A digital signature doesn't have to resemble a handwritten signature in any way, which is a common misconception. In fact, it's more about the authenticity and integrity of the signature.
Using an electronic signature on a mobile phone is useful for companies that need to approve contracts remotely. It's a cornerstone of daily business operations, especially for those operating remotely.
Signing documents on a mobile phone offers numerous advantages. Here are some of the main reasons why it makes sense to sign documents on your mobile phone:
- Mobility and flexibility: You can sign documents from anywhere, whether in the office, at home, or on the move.
- Time saving: You can add a digital signature with just a few clicks and send the document immediately.
- Environmentally friendly: You can reduce paper consumption and save on printing and paper costs.
- Security: Modern digital signature processes used on mobile phones offer high security standards.
- Increased efficiency: Documents can be processed and approved more quickly.
- Easy to use: Even less tech-savvy people can easily create digital signatures.
- Legal recognition: Digital signatures created on mobile phones are legally recognised in many countries.
Digital signatures created on mobile phones are considered just as binding as handwritten signatures, making them a reliable option for legally valid transactions.
Creating and Managing Digital Signatures
Creating and managing digital signatures on your phone is easier than you think. You can use the PandaDoc e-signature app to create and manage signatures.
The app allows you to sign any document at lightning speed, and you can do it in multiple ways. You can draw a new signature on your touchscreen device, type your name, or upload a pre-drawn copy of your signature.
To create a new signature, you can capture images with your phone camera, upload a file, or choose an image from your gallery. This gives you flexibility and convenience.
Here are the steps to create an electronic signature and sign documents on a phone:
- Locate the document you need to sign from your document dashboard.
- Review the document, along with any fields that require additional information.
- Fill out any outstanding fields.
- Follow the prompts to e-sign and complete the document.
You can also manage existing documents or prepare and send new documents to other signers through the app. To do this, tap on the “+” logo and choose how you would like to upload a document.
Once your document is completed, you'll receive a signature certification to accompany your document. This digital certificate includes a document reference number, the recipient's name, and other identifying information to prove when the document was signed and completed.
This makes electronic signatures from phones much more secure.
Security and Storage
Electronic signatures on Android devices are surprisingly secure, thanks to encryption that protects data both when it's stored and on the move.
Signeasy's electronic signature app for Android devices is a great example of this, and they even recommend setting a 4-digit passcode for extra security.
The Signeasy app itself is relatively small, taking up just 70mb of phone storage when you download it.
