All the technical stuff. Let us take care of it
Barcodes 1D and 2D
Barcodes systematically represent data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D). Later they evolved into rectangles, dots, hexagons and other geometric patterns in two dimensions (2D). Redegroup can digitally print a full range of 1D and 2D barcodes.
Magnetic Stripes
A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of a band of magnetic material on the card. The magnetic stripe, sometimes called swipe card or magstripe, is read by swiping past a magnetic reading head. Magnetic stripe cards are commonly used in credit cards, identity cards, and transportation tickets. Redegroup can produce plastic cards with HiCo (High coercivity) and LoCo (Low coercivity) mag stripes.
When preparing data to be encoded onto a mag stripe it is important to remember that the tracks of a mag stripe can be encoded using the following spec
- Track 1 – Max 76 characters – alpha, numeric and spaces allowed
- Track 2 – Max 37 characters – numeric only
- Track 3 – Max 103 characters – numeric only
Please note that some card readers show the start and end sentinels e.g. ; ? % these are machine generated and do not form part of the data, please do not include them in your data fields.
