## Key challenges
A smart-case typically houses a battery pack, the main controller board and the electromechanical components that interface with the buttons/ports of the phone/tablet that fits into it. The need was to develop uniform solution across various platforms Android to Windows-based tablets and phones.
#### Developing a uniform solution that works and exhibit consistent app functions across various platforms from Windows to Android
The company distributes a host of different types of smartcases that can be integrated with Android and Windows smartphones and tablets thus solution needs to function smoothly on these platforms.
#### Robustness with mobility
A smartcase can perform in the harshest conditions while providing workers and enterprise users with the durable technology they need to get the job done so the key demand was to make solution network connectivity robust to even accommodate any random outages.
#### IoT compatible with seamless cloud connectivity
The smartcase also comes with an integrated array of cloud-connected sensors case that measure shock, vibration, temperature, humidity, and barometric pressure independently by utilizing smartphone devices as an engine.
#### Custom solutions instances to accommodate end-client variation domain to domain
The smartcase provides out of the box flexibility by making the endcaps swappable. This allows enterprises to make their own customized business-class smartcase suitable for their business needs and also allows them to upgrade them as and when needed.
## Approach
e-Zest has been a development partner for the company, delivering the entire software-side for the products. Its focus was on building a wide range of APIs that can be utilized to access the data captured by the smartcase and can be reflected in custom web or mobile apps. Later, custom mobile apps were designed to leverage the smartcase APIs whereas custom web apps were architected to leverage the Server REST APIs.
## Solution
#### SDK development
Developed the software development kits that need to be integrated into custom mobile apps for leveraging the range of features offered by the smartcase.
**The web app, sample apps, and API development**
- A full-fledged web application that displays the information captured by the smartcase was developed
- Developed sample mobile and web apps that provide complete source code to authorized users
- Developed all the APIs needed to sync the data back and forth between the mobile apps
#### Enterprise appliance module
The module provides an interface to the programmable indicator lights beneath each of the softkeys fitted on the smartcase. The indicator light’s color, intensity, and illumination pattern can be programmed directly through this interface.
#### Barcode HID module
The barcode scanner hardware is attached to the endcap of the smartcase as a Human Interface Device (HID). When a user presses the ‘action’ button on the smartcase, the barcode scanner comes into action, detects and recognizes a barcode held in front of it.
#### Environment module
The smartcase sensors include environmental sensors that measure the temperature level, relative humidity, and barometric reading. Using the environment module, an app can query the environmental sensors in the smartcase.
**Shock module and acceleration module**
- Shock module provides an interface to the get the shock and drop analysis captured by the smartcase. It uses data provided by the acceleration sensing peripheral to monitor impact and shock conditions, to record critical conditions, and to issue alerts.
- Acceleration module provides an interface to retrieve acceleration readings by setting the acceleration notification rate
#### EMV HID module
The EMV (Europay Mastercard Visa) module can be used to swipe a debit/credit card and make payments on the go by integrating with a payment gateway.
## End result
All the features of the platform are exposed through the platform APIs, a RESTful (representational state transfer) interface that communicates via HTTPS and uses JSON serialization for data. This API enables integration of the smartcase features and automation into any custom web or mobile application.
e-Zest also provides continuous maintenance support for the SDKs and APIs developed so far for:
- App crash and performance monitoring
- Bug tracking and fixing
- Minor incremental feature enhancements
- Minor modifications in existing SDKs and APIs
- New feature or API development was taken up as change requests
- App optimization for new OS updates
- App distribution for new app versions
- App analytics monitoring
#### BridgePay payment gateway integration for EMV module
The BridgePay payment gateway returns the transaction response in terms of payment success/failure, the transaction value, partially masked account number, card type and so on which can be used to make payments on the go.
#### License-based feature access
API licensing model allows the company’s admin to explicitly define which features and functions of the smartcase are available to an enterprise based on the purchased subscription and endcaps. For example, which peripherals or sensors may be utilized.
