Barcode entry
A good starting point is to understand what kind of bar code that best suits your application, you may include taking into account the needs and requirements of industry and related regulations. At the same time, we must clearly understand the business needed to support your character set, there are a variety of other technical considerations. Specifically, developers need to weigh the advantages and disadvantages between the development and purchase of its own components.
Supported barcode
If you want to develop a bar code recognition applications, eventually, you might turn to the SDK to save time, resources and costs. Therefore, you need to make sure SDK barcode recognition can support your needs. This means that it has the ability to decode one-dimensional (1D) and two-dimensional (2D) bar codes. It should also allow decoding from mainstream sources (such as images, PDF files, or camera).
Supported Platforms
You need to verify SDK can work across platforms. This includes desktop applications you may have created in .NET, or if you use web-based approach, you can create desktop applications using mainstream web browser. Now, with the number of mobile end users increasing number of mobile client application can not be ignored. Therefore, we must consider whether the SDK and webcam capture from a smart phone camera and scanning bar codes, whether photographs or live video streaming camera.
Supported programming languages
You should also select the SDK for easy integration into your application. Therefore, it should support some important API, such as C, C ++,. NET and JavaScript, as well as 32-bit or 64-bit environment. It should also support the widely used programming languages, such as C #, VB.NET, Java, C ++, VBScript, JavaScript, Python, Perl, Ruby, Swift, Objective-C and so on.
Optimization options
We talked about the importance of the bar code recognition software to scan the page to customize the location. In addition to the area scanning function, well SDK also enables developers to set the page to be scanned. This should allow each page includes a bar code scanning, or across a single or multi-page multi-code scanning. Equally important, the SDK can be handled in the scene being scanned by preprocessing the defective barcode, barcode including inclined, and the damaged bar code unreadable barcode.
Vendor technical support
If you need technical support, make sure SDK vendor provides technical support for a variety of ways. E-mail exchange is a very common way of support. So make sure you choose vendors also offer a more immediate technical support options, such as chat and phone support.
SDK update frequency
Finally, consider how often you how often to update the SDK vendor products. You need bar code recognition software that can be realized today features may vary in the future. So, if your vendor does not actively improve their products, then they'll probably can not support the new features you need.
