How can I know if my cards are HICO or LOCO?

The easiest way to visually determine if a stripe on a card is Hico or Loco is by checking the color of the stripe. Hico stripes are black and Loco stripes are brown. This information applies to magnetic cards provided by Evolis but does not hold good for all manufacturers.
If you are using cards from another manufacturer, please check up on the specifications.
