  • Identification and verification

    Because of the growing complexity of production processes good tracking & tracing and quality control is essential. Often different products are produced on the same production line on the same day varying in size, content and destination. Errors can easily occur. The right information on the product or carton is important for the customer thinking of ingredients and allergies.

    Therefore, when thinking of an ID reader don’t think of a ‘simple’ reader that scans a barcode. Nowadays there a camera based ID readers that can read 1D and 2D codes and can check the presence and content of packaging or labels including text and numbers.

    Barcodes

    barcode
    • Barcodes can be read with a ‘simple’ ID reader, 2D codes cannot.
    • More often camera based ID readers are used for both 1D and 2D codes.
    • Camera based ID readers capable of reading damaged codes.
    • They can judge the quality of a code an send a signal if the quality drops below the standard.
    • A read quality guarantee conforming the international ISO-standards can given.

    2D-codes

    • Information in two dimensions.
    • Information is translated to black en white cubes.
    • The code is redundant meaning: the code contains the information multiple times en is therefore less sensitive to damages.
    • Information can be read regardless of positioning (upside-down), the special border acts as a reference.
    • Contains a lot of data.
    • Can be used on uneven surfaces.
    2D code

    OCR and OCV

    OCR-op-stalen-coils
    • Optical Character Recognition/Verification is for example used to read ‘human readable’ text such as production dates.
    • The ID reader can ‘learn’ a specific font so that it can check the text.
    • Subsequently is can give a signal when the text is or becomes unreadable.
    • The operator can then intervene to prevent rejects, failures and/or recalls.
