US provider of barcode verification technology Webscan has announced the launch of a new system TruCheck 2D UV, which can verify invisible 2D bar codes that are visible only under UV light.

Webscan claims that the first commercially available hand held 2D barcode verifier for invisible barcodes incorporates UV wavelength LEDs and a UV sensitive CCD camera and is used in security applications such as track and trace.

Webscan president Glenn Spitz said the TruCheck 2D UV allows printers to verify the readability of invisible bar codes and diagnose printing issues.

"From anti-counterfeiting and other security applications, to simply printing a code that does not disturb the graphics on a package, invisible barcodes are gaining more and more interest across several industries," Spitz added.

The system is operated by the company's software interface which can verify 1D (linear) and two dimensional (2D) bar codes, Webscan said.
