TQS Code Reader

The TQS Code Reader is an application for decoding and checking 1D and 2D codes. The app checks the code content for conformity with the current specifications of GS1 (www.gs1.org) and IFA (www.ifaffm.de). It supports the most important code types.

This app has been developed from scratch. It contains many improvements, such as a new GS1 and IFA data parser and validator. In addition, data content is now not only parsed, but also interpreted to give you an even better understanding of the code content.

Scope of services
The app allows the reading of the following code types: Code 39, Code 128, EAN-8, EAN-13, UPC-A, UPC-E, ITF, QR Code and Data Matrix. The code content is parsed to interpret an check the contained data.

Checks performed
The code content is checked according to the following criteria:

Checking the structure
- Invalid pairs of element strings
- Mandatory association of element strings

Checking the contents of the individual identifiers
- Used charset
- Data length
- Check digit
- Control character

Display of inspection results
The inspection results are displayed clearly and structured. Control characters are replaced in the raw value field by readable characters. Each detected element is displayed separately with its value. Reasons for errors are displayed and an overall result of the check is visualized.

Storage of inspection results
Scanned codes are stored in a history database. From there, the inspection results can be retrieved again.
