The software uses different tiers to determine the usage limits per month:

: Includes up to 300 scans per month and support for one smartphone. Pro/Unlimited Licenses :

When a user enters a serial key into the server software, the system typically validates it through one of two methods:

Often because the free/trial version has limitations (e.g., number of scans, device connections, or nag screens). However, using unauthorized keys is software piracy, which carries legal and security risks — including malware from keygen tools.

This paper explores the technical architecture of modern Wi-Fi-based barcode scanning applications, specifically focusing on the paradigm where a smartphone acts as a barcode scanner and transmits data to a PC server via a local network. It examines the client-server model utilized by applications such as Barcode to PC , the role of the "Serial Key" in software license management, and the security protocols involved in authenticating legitimate software usage.

The security of the serial key system is critical for the software vendor.
