Barcode Reader SDK pre-sales questions

[SDK] I would like to test the SDK before purchasing a developer license.
Please go to Download page. Fill all required fields and select Platform. We'll send you SDK ASAP.
[SDK] What is an SDK? Does it have to be bought each time or is it a one-time fee?
The SDK (software development kit) is develorer license. The SDK is required for each developer to integrate our BarcodeReader into your application.
Our barcode decoding software is distributed as an SDK (developer license) and under a runtime license.
The SDK is necessary for every developer to be able to integrate our DataSymbol Barcode Recognition SDK into his applications.
A runtime license is required for every PC (or server) where our BarcodeReader component will be installed.
The SDK includes one developer license and one runtime license.
You have to buy the SDK only once. Suppose you have 1 developer and want to install our barcode reading software on 20 PCs, so you will have to purchase one developer license and 20 runtime licenses.
[SDK] What is the difference between the standard and professional editions?
The standard edition allows you to decode only one barcode in one file. The professional edition has no limitations.
