Why Your Business Should Switch to Dynamic eSignatures (And How to Do It)

Paperwork is becoming less and less popular in institutions and organizations. This is because physical documents are time-consuming, prone to human errors, and cumbersome. So, how do you operate without paperwork?

Well, technologies like eSignatures have become the cornerstone of secure and efficient document workflows. To make this work within your own software, you’ll usually need a PDF SDK. This tool lets developers bake advanced document processing features—essentially the “engine” for signatures—directly into applications across mobile, desktop, web, and server platforms. Much like how AI-powered spreadsheets are helping teams stop wasting hours on manual data entry, these digital tools are all about reclaiming your time and reducing friction.

Once you integrate it, you can sign PDFs entirely client-side using an open-source UI without ever needing to ping an external server. And the best part? Because it’s open-source, you can automate the whole thing programmatically, whether you want the heavy lifting done on the user’s device or your own server. Implementing dynamic eSignatures through a Core SDK is a game-changer for streamlining and securing your document process. Read on!

What Are Dynamic eSignatures?

A dynamic signature is a type of electronic signature designed to capture and verify the biometric characteristics of your handwritten signatures during the signing process.

Unlike the traditional e-signature process that only captures a static image of your signature on a digital document, dynamic eSignatures capture your specific habits—things like speed, pen angle, timing, and stroke order. This usually happens on a touchscreen. These signatures are harder to forge because they are unique to each signer.

Why You Need a Core SDK for eSignatures in PDFs

A core SDK is what allows you to tuck eSignature functionality right into your existing apps so the signing experience feels seamless. The benefits of doing that are:

• Full control over the signing process: Your system sends a document and signing instructions to the eSignature API, which then handles the signing process and returns the document to you. You can tweak exactly how the signature looks, set your own validation rules, and pin the signature position wherever it needs to go, no matter what device the person is using.
• Enhanced security: Electronic security in eSignatures ensures your documents are protected, which minimizes data loss risks. Core SDK APIs provide real-time status updates on the signing process.
• Conform with legal standards: Embedding legally binding signatures ensures you conform with standards like XAdES and PAdES. These standards rely on underlying cryptographic algorithms that make documents tamper-evident.

How to Add Dynamic eSignatures to PDFs

The process is quite straightforward.

1. Choose a Reliable PDF eSignature SDK You want a tool built with usability in mind to complete the signing process with ease. It should be easy to integrate, secure, and offer multiple signature types.
2. Set Up the Development Environment Next, install the SDK and the required dependencies. This includes test files and all the tools you’ll need to start coding. You can see a complete guide to SDK here.
3. Add a Digital Signature Approval Field This is where the next person will need to sign. As we touched on before, open-source solutions let you automate this programmatically on the client or server side, keeping everything private and local.
4. Digital Signature Application Once you have an approval field, use cryptographic signing to embed the signature. This involves using a private key for more security and “baking” the signature into the file so you can tell immediately if someone tries to tamper with it later.

Real-Life Use Cases

• Legal and Finance: In sectors dealing with high-stakes contracts and loan agreements, dynamic signatures prevent alteration and provide a robust audit trail.
• Healthcare: Clinics use secure signing to protect medical forms and prescriptions while ensuring they meet strict data privacy regulations.
• Small Business Efficiency (The Cost-Saving Angle): For small law firms or local medical practices, the cost of “per-envelope” or “per-signature” fees from major providers like DocuSign can be pretty eye-watering—often hitting $480 to over $700 per user every year, even for limited documents. By using a Client-Side SDK, these businesses can process as many signatures as they want for one fixed cost. It stops the bills from skyrocketing just because the business is growing.

Final Thoughts

Adopting dynamic eSignatures not only streamlines your document workflows but also ensures you are legally compliant. That’s the reason you need secure and verifiable signing processes in digital documentation.

If you’re heading in that direction, make sure to pick a solution that follows local regulations, like the ESIGN Act in the USA or eIDAS in the EU. The SDK should also offer strong authentication methods and keep the signature fields clear and intuitive.
