Magnetic Stripe settings used by the Select
printer
The following table presents technical details that apply to encoding magnetic stripe
data.
Magnetic Stripe Setup
Do the following to set up the printer and printer driver to encode magnetic stripes on
cards:
• Use cards with magnetic stripes when making a printer test card.
• Determine the coercivity to use. Usually, the coercivity is system-wide decision:
magnetic stripe readers are likely to require a specific coercivity value. Card stock
is purchased to match that coercivity value. Set the coercivity in the printer driver.
• Select the encoding format. If a custom format, such as triple-IATA, is used, select
Binary or “Use Printer coercivity” in the printer driver.
