## Abstract of Electronic Signature App

E-Signature App is a France-based signature app for the Android platform. It is available for worldwide users. With the help of this eSignature app, you write details, draw initials and signatures, give stamps, and share documents. In fact, you can scan papers and sign documents before you share the complete PDF file with your contacts using various options, such as email, Skype, Bluetooth, and social media platforms.

Moreover, this signature app allows you to import or upload your documents easily via OneDrive, Google Drive, Dropbox, Box, Gallery, or photo scanning. Create your customized signature and initials directly on your mobile device and start signing the documents digitally. This app converts image documents into PDF files, and those files are easily shareable with your contacts.

## About Our Client and His Requirements

Our client is from France, and he is an entrepreneur. He deals with several organizations and clients. However, the increasingly paperless business also put a lot of pressure on him to move towards digital solutions. He was facing challenges to manage all the essential documents on time, and it was challenging for him to streamline operations, and maximize efficiency.

With such challenges, he started looking for a custom solution that can contribute to a paperless office environment where every document is properly digitized with an e-sign for legally binding. Being an entrepreneur, he thought of creating his own e-signature app that can help him and millions of people for having a paperless workflow and centralized document storage.

Our client knew that many organizations are now moving toward digital solutions. His idea of creating an e-signature app can actually help people around the world to streamline their work process, enhance security, track documents, increase contract speed, and lower transaction costs.

To develop one such signature software, our client contacted us with his requirements. We and our client have already collaborated before on an iOS project. Therefore, he immediately approached Space-O Technologies without giving it a second thought, seeing his old app’s success.

## Solution We Provided to Our Client

When our client approached us, he was already clear with his mobile app idea for the E-Signature App. Therefore, it was easy for our mobile app developers and project managers to understand his requirements. We implemented his idea of a digital signature app and started to work on it.

Our business team prepared a WBS (Work Breakdown Structure) document that helped him to understand the structural view of the project. We also came up with an interesting feature that can directly import documents from cloud storage using Amazon S3. Amazon Simple Cloud Storage (S3) provides the highest level of data durability and availability on the AWS Cloud.

Apart from this, we have integrated many essential features into the app, such as scanning, filtering, and cropping documents. It is easy to add multiple initials and signatures, along with customized stamps and dates. In fact, we suggested our clients add a feature of passcode and Touch ID to protect confidential data.

## Challenges We Faced While Developing This E-Signature App

While developing this e-signature app for Android, we faced some minor challenges. However, all the challenges were resolved later.

Firstly, it was getting difficult to add the scan functionality to the app. But our Android app development team did a lot of research to identify the best Android library that can help in adding the scan feature. During the R&D process, we found that Firebase offers a Machine Learning library that helps to add the scan functionality in Android apps.

Also, during the custom app development process, the memory consumption was high. The app was taking a lot of time (1 – 2 minutes) to convert into PDF from the image, and the app was also crashing. However, default libraries are already available in iOS for such tasks. But for Android, such default libraries were not available.

To walk the extra mile, app developers enhanced the code and improved its quality. Now, it is easy to convert images into PDF form within a few seconds. Also, the app doesn’t crash anymore. The effort of the team behind building this application proves that we always strive to deliver exceptional results.

## Results

![Remote Access to Save Time](https://www.spaceotechnologies.com/wp-content/uploads/2021/08/remote-a.svg)This E-signature App works remotely and helps you sign and send documents quickly from anywhere, anytime, and on any Android device. It saves you time as there is no need to print, scan, or post a document.

![Keep Documents Secure and Safe](https://www.spaceotechnologies.com/wp-content/uploads/2021/08/keep-document-se.svg)Paper documents are fragile and can be damaged. However, using this app, you can keep the documents safe with a passcode. Also, no one can access the documents without your consent, as the app will be locked with the Touch ID.

![Cut Down on Stationery Costs](https://www.spaceotechnologies.com/wp-content/uploads/2021/08/cut-dow.svg)Compared to the traditional method of wet ink signature, using e-signatures to sign pdf electronically is more cost-effective. Printing paper and ink cartridges aren’t cheap, and with a digital signature, there’s no need to spend money on either.
