Metapack integrates grade verifiers systems named TruCheck USB TruCheck and 2D Omni. These systems are developed by Webscan an American company founded in 1995 to design and build the world’s most accurate bar code verification systems.

In addition to selling, Metapack provides all the additional information on the use and can support customers.


Grade Verifiers named TruCheck USB and TruCheck 2D Omni are systems that can verify your largest and smallest 1D and 2D codes getting accurated results at every time. Whenever verifying 2D bar codes, Webscan’s systems are ready for any current and future requirements.

TruCheck USB

TruCheck USB provides a full integrated and portable TruMatrixäimaging head connecting to a PC through the USB port. It only needs to position the image over a bar code and to press the button, clear and concise results are instantly displayed. The graphic interface shows operators clearly where potential problems exist. The TruMatrixäimager features integrated illumination and a rugged housing: there’s nothing to focus and nothing to allign. The most accurate and repeatable verification results are always guaranteed.

MIL-STD 130N Requirements

Webscan offers a complete solution to handle all the requirements called out in MIL-STD 130N, from label verification to direct part marketing. Reports clearly show if your bar code passes the MIL-STD 130N acceptance criteria, including the SC and MOD.

UID Data Validation

Data content of the UID mark is validated and given a pass/fail grade. Data format failures and causes are clearly spelled out to make corrective action easy. The Unique Item Identification UII is printed clearly on the reports. Verification and validation information can be printed out, stored electronically or used in 3rd party software solutions.

TruCheck 2D

TruCheck 2D Omni has an extra large field of view (up to 6 inches wide) and super high resolution. You can select multiple areas within your image so you can verify every barcode on a blister card, or several bar codes on a shipping label all at once. Using its high resolution 5 MP camera, the TruCheck Omni accurately creates any size round aperture to higher precision than relative low resolution competitive models.

Calibration and traceability

TruCheck 2D Omni is calibrated and fully traceable to NIST standards. Calibration is performed by the user in a matter of seconds. Using long lasting solid- state LEDs, the system evenly illuminates the large field of view with correct wavelenght red light, not hot, expensive halogen white lights that require a red filter and need to be replaced regularly. When the unit is not in use, you can exit Live Mode to turn off the LEDs, saving your company’s money. You can also always know that your system is measuring accurately with Webscan technology.

Meets requirements of every industry

TruCheck 2D Omni meets GS1 standards and complies with ISO/IEC standards for both 1D and 2D symbol quality measurement and accuracy compliance, including ISO/IEC 15415, ISO/IEC 15416, ISO/IEC 15426-1, and ISO/IEC 15426-2.

Data validation  

TruCheck 2D Omni check the syntax of 1D and 2D bar codes to confirm that the data content doesn’t have any errors. The hinged cover holds labels down for precise verification results and protects the window when not in use. The system quickly shows you the content and meaning of GS1 coupons, pharmaceutical labels with expiration dates and lot numbers, or any data which follows common industry standards such as GS1 application identifier formats.
