Description
The Operator Identification Card Reader is a special attachrrent
for the 3270 display station and is used to send coded messages
to the computer. The card reader is attached to the display
station through a 30-inch cable, as shown in Figure 39. When
your display

a coded message to the computer by inserting a special

begin operating the display station.
A specially designed (coded) credit card may also be used to

code, which identifies the person using the card reader or which
represents an account number, is contained on a magnetic stripe
attached to the back of the card.
