A method and system for recording and storing digital data on optical memory stripes of smart/optical cards using laser recording of optical storage media to create updatable, high resolution, two-dimensional bar codes, storing about 15 to more than 500 times as much digital data as the widely-adopted PDF-417, two-dimensional bar code. The optical storage media is of the DRAW (direct-read-after-write) type which requires no post processing. The optical storage media is pre-formatted with tracks to precisely locate the recorded microscopic data spots. Groups of these microscopic data spots form data bars which in turn form data pixels whose dimensions are at least four times greater linearly and 16 times greater in area than the microscopic data spots. The data pixels on the optical memory stripe can be read with photodetector arrays such as CCD arrays.

A method of creating digital data pixels readable with photodetector arrays from laser-written, microscopic data spots on the optical memory stripe of a smart/optical card comprising,
An optical memory stripe or patch on a smart/optical card readable with a photodetector array comprising a wallet-size smart/optical card having an embedded microchip microprocessor and a strip of optical contrast pre-formatted DRAW laser recording material disposed thereon, a plurality of laser-written microscopic data spots create a plurality of data bars recorded on said strip with at least two said data bars on each track having a track width at least three times greater than the width of the data bars and the combination of at least two adjacent tracks having said data bars recorded thereon, forming a data pixel among many data pixels as a region whose smallest dimension is at least seven microns and which encompasses at least 2n data bars which are approximately n to 2n track widths long and that portion of the n tracks encompassed containing at least 2n said data bars, and where information represented by said data pixels is read with a photodetector array for transmission to one or more parties involved in transactions or data transfers that utilize said microchip microprocessor.
