ZXing.Delphi
A native Object Pascal barcode scanning library for Delphi VCL and FireMonkey applications, based on ZXing.
What is ZXing.Delphi?
ZXing.Delphi is a native Object Pascal library that ports the popular ZXing (Zebra Crossing) barcode scanning engine to the Delphi ecosystem. It enables developers to integrate fast, dependency-free barcode scanning into their VCL and FireMonkey applications for Windows, iOS, Android, and macOS. The library is designed to be simple to use, highly performant, and fully integrated within Delphi projects.
Delphi developers building VCL or FireMonkey applications for Windows, iOS, Android, or macOS that require barcode scanning functionality. This includes developers creating point-of-sale systems, inventory management apps, or mobile scanning utilities.
Developers choose ZXing.Delphi for its native performance, avoiding external library dependencies and compatibility issues, and its seamless integration directly into Delphi projects without license fees. It offers a comprehensive, multi-platform solution with a simple API and wide barcode format support.

ZXing Barcode Scanning object Pascal Library for Delphi VCL and Delphi Firemonkey
Use Cases
Best For
- Building Delphi VCL applications for Windows that need embedded barcode scanning without external dependencies.
- Developing cross-platform FireMonkey mobile apps (iOS/Android) with integrated barcode scanning capabilities.
- Creating inventory or asset management systems in Delphi that require scanning 1D industrial codes like Code 128 or Code 39.
- Implementing QR code or Data Matrix scanning in Delphi-based point-of-sale or ticketing applications.
- Adding barcode scanning to existing Delphi projects with minimal setup and no licensing costs.
- Developing native macOS applications with Delphi that require fast, compiled-in barcode scanning.
Not Ideal For
- Applications requiring scanning of advanced 2D barcodes like PDF417 or full Data Matrix support, as ZXing.Delphi has limited Data Matrix coverage and misses some formats.
- Projects built with Delphi versions outside XE7 to 12 Athens, due to compatibility constraints and potential breaking changes in newer IDEs.
- Teams seeking plug-and-play solutions with built-in camera UI and advanced features, as camera integration and optimization must be handled separately by the developer.
Pros & Cons
Pros
Compiles directly into Delphi applications, eliminating external library dependencies and ensuring fast execution without compatibility issues, as highlighted in the README's emphasis on avoiding external libraries.
Works seamlessly with both VCL for Windows and FireMonkey for iOS, Android, and macOS, enabling single-codebase multi-platform apps, as confirmed by compatibility testing across these frameworks.
Supports key 1D codes like UPC, EAN, Code 128, and 2D codes including QR Code, covering most business and industrial needs, with unit tests provided for reliability.
Features an easy-to-use TScanManager interface, demonstrated in the minimal code example for quick integration, reducing setup time for developers.
Cons
Data Matrix scanning is restricted to centered images only, and other formats like PDF417 are not implemented, limiting use cases for advanced barcode applications.
No built-in camera component; developers must implement capture and bitmap processing themselves, and set compiler defines (FRAMEWORK_VCL/FRAMEWORK_FMX) for framework compatibility, adding complexity.
Requires Delphi XE7 to 12 Athens, making it unsuitable for projects on older or newer unsupported Delphi versions, as noted in the README's compatibility list.
