The present invention is directed to a method of transferring a chunk of data between unconnected computing devices. A first chunk of data present in a source computing device can be in a first format that is binary data or nonstandard characters. Encoding, by the source computing device, the first chunk of data to a second chunk of data. The second chunk of data is in a format that is of standard characters. Capturing an image of the second chunk of data by an optical sensor. Receiving of the image by the target computing device. Processing of the image, by the target computing device, to the second chunk of data. Decoding, by the target computing device, the secondary chunk of data to the first chunk of data.
