Signing Documents on the Go: How to Sign a Document on iPhone

In today’s fast-paced digital world, the ability to sign documents quickly and efficiently is crucial. Thankfully, with the advent of smartphones, signing documents on the go has become easier than ever before. iPhones, in particular, offer a convenient platform for e-signatures, enabling users to sign important papers anytime, anywhere. 

This article explores what is electronic signature, how to sign a document on iPhone, and provides an overview of the top e-signature tools available for iPhone users.

What is an E-Signature?

Before delving into the e-signature tools for iPhone, it’s essential to understand what e-signatures are and their legal validity. E-signatures, or electronic signatures, are digital representations of a person’s signature that are used to sign documents electronically. 

An electronic signature, or e-signature, is defined as “symbols or other data in a digital form attached to an electronically transmitted document as verification of the sender’s intent to sign the document.” In other words, this allows a signer to give consent or show they approve of the document’s contents. Because of this, a digital signature today is regarded the same as a stamped seal or handwritten signature. To illustrate, years ago, warehouse management ran smoothly without e-signatures. However, today, there is a variety of warehouse management software that require online verification, including signatures.

Is it both legally valid and secure to use electronic signatures on the iPhone and iPad?

The answer is, yes. Electronic signatures on the iPhone and iPad, when utilizing reliable and secure electronic signature softwares like DottedSign, are both secure and legally recognized

According to the Federal Deposit Insurance Corporation, an e-signature is defined as “an electronic sound, symbol or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record.” This essentially validates an e-signature as long as the signing is tied to a contract or electronic record and intended to function as a signature. 

While often appearing in the digital form of a traditional wet ink signature, an e-signature can also look like this:

  • Consenting to the terms and conditions of a website by clicking “I agree” or something similar.
  • Typing your name into an online form.
  • Signing your name on a mobile device with your finger. 

It’s important to note that the legal recognition of electronic signatures may vary by jurisdiction. However, with DottedSign’s commitment to compliance and adherence to legal standards, you can be confident that your electronic signatures on the iPhone and iPad are secure and carry legal validity in many jurisdictions.

Ultimately, the legitimacy and validity of an e-signature are not decided by the device you use, but the e-signature tool you use.
