inserted, or the probe is touched to a button. The button is read automatically whenever the printer is awake and the button is sensed by touching with the probe. The magnetic card is read when the printer is awake and the card is moving. This data is stored in an internal buffer in the printer and available to the host via RS-232 or IrDA. Data directly from the smart card can be read by command from via RS-232 or IrDA

Magnetic Card Reader

Although insertion type card readers such as the one used on the reader can read cards either upon insertion or withdrawal, the read rate is much higher upon withdrawal with virtually all readers of this type (e.g. the gas pump readers). This is because the card is unstable and the rate of movement can change drastically when the card is first inserted. If the reader is already awake, and more than one card could be inserted, the application may choose to zero the buffer before prompting the insertion of the card to assure the data is from the card about to be inserted, and not a previously read card.

An application, then, may choose the following sequence if the operator of the equipment is trained (i.e. not a “consumer” end user); this uses the automatically generated LED/Buzzer status indicators

∙Handheld prompts the user to insert, then remove card

∙Operator inserts card (waking up the reader) and waits for green LED, then removes card

∙Handheld polls the 2tcr/2icr/4tcr waiting for data to be available

Or, if the operator is an “untrained consumer”, the application may choose a more step-by-step approach and handle handheld screen prompts and LED/Buzzer as required:

∙Handheld prompts the user to insert their card

∙User inserts the magnetic card into the card reader slot waking up the reader

∙Handheld polls the reader looking for the card to be inserted

∙When the handheld sees the card is inserted, it prompts user to remove card

∙2tcr automatically reads and buffers card data from any or all of Tracks I, II, and III

∙Handheld polls the reader looking for the card to be removed

∙Handheld requests card data from reader
