Method Documentation

read:error:

- (NSArray *) read:		(NSInteger)	timeoutMS
error:		(NSError **)	error

Activates the printer's magnetic card reader, if present, and waits for timeoutMS milliseconds for a card to be swiped.

If the printer does not have a reader the call will timeout.

Parameters

timeoutMS	The amount of time in milliseconds to enable the reader and wait for a card to be swiped.
error	Will be set to the error that occured.

Returns

An array of three strings corresponding to the tracks of the card. If a track could not be read that string will be empty.
