Method Detail

read

String[] read(int timeoutMS)
              throws ConnectionException

Activates the device's magnetic card reader, if present, and waits for a card to be swiped. If the device 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.

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.

Throws:

ConnectionException - if an I/O error occurs.
