Abstract
Improved techniques involve transferring data into a target device using bar codes. Along these lines, suppose that someone wants to send a message to the target device via a source device. For some messages, the source device may encode the message into a single bar code that the target computer may decode back into the message. However, for a sufficiently large message, the source device breaks the message into a series of message portions, encodes each of the portions into a distinct bar code, and outputs the bar codes, e.g., on sheets of paper using a laser printer. From these sheets, an operator scans each bar code into the target device. The target computer then decodes the scanned bar codes back into message portions and reassembles them into the message.
