Barcode – effective yet inexpensive
Barcode represents a basic and the least expensive security element, which may be supplied as a standalone source of identification or in combination with the cardholder’s name. Black barcode may be printed on a background of any colour; however white colour is used as a standard, since it secures the best scanning reliability. The specific types of barcodes differ in barcode length, number of signs to be coded, type of signs to be coded and a minimal printable barcode width.
In case you are unsure which barcode is the most suitable for your needs or how it should be positioned on a barcode card, please see technical specifications.
Barcode technical specifications
- The height of a barcode may vary, but should not fall below 6 mm without digits and 8 mm with digits.
