The cheapest form of high-quality plastic cards are barcode cards, where the data is represented in binary symbols. In general, barcodes are also known as barcodes, barcodes or barcodes.

To prevent wear and tear of the barcode during use, the cards can be protected by means of an overlay or lamination. Alternatively, it is possible not to print the barcode directly onto the plastic card in the conventional way, but to transfer it into the material by laser.

A further development of the original 1D barcode technology are QR codes (2D barcodes), which can be read by cell phone scan and thus provide the user with a wide range of information. With a QR code, you can link to your website or contact information.
