A multiresolution optical code can be encoded. A first set of information and a second set of information to encode in an optical code is received. An optical code that encodes the first set of information in a plurality of dots is generated. Each dot of the plurality of dots is divided into a matrix of a first number of sub-dots by a second number of sub-dots, wherein each of the first number and the second number are integers equal to or greater than three and wherein this dividing creates a set of matrices of sub-dots. The second set of information is encoded in a plurality of the sub-dots of the set of matrices of sub-dots.

Systems and methods are disclosed herein for overcoming the limitations of placing QR code onto a business cards or paper and to be scannable by a smartphone camera and a method for utilizing a QR code to receive instant reviews. The method allows customer feedback acquisition and processing system by printing QR code on a business card or paper and when required the code can be scanned to leave an instant review to the destination website. The proposed method may also be used with packages and invoices.

Aspects of the present disclosure involve systems, methods, devices, and the like for generating an unobtrusive and discrete barcode used for debugging. In one embodiment, a system is introduced that enables the tracking of application interactions on a user device. The tracking can include the generation of a debug id which can include a discrete string used to describe locations, preferences, and interactions with a user device application. The string may then be converted into a corresponding barcode which can be discretely displayed on the user interface of the application. In another embodiment, the barcode may be captured and/or retrieved for use in debugging the application, in an instance where an application malfunction is encountered.

Embodiments of the present invention provide a system for secure communication of information that may be used to authorize communications or transfer of resources by use of a transient pliant encryption mechanism in conjunction with an indicative nano-display. The provided systems, methods, and computer program products are designed to select and apply multiple encryption algorithms in a varied fashion and update displayed information on a nano-display. Credentials for a user may be stored and securely communicated via a transient nano-display that is updated at a configured interval of time and is indecipherable to unauthorized third parties.

A wearable computing device reads near-invisible one- or two-dimensional barcodes having a size of 100 microns to one millimeter.

According to the present disclosure, methods and systems for producing a microscale optical code on a precious object and reading the microscale optical code are disclosed. The method comprises the steps of providing an object, providing at least one marking unit, inscribing an array of micro-indents or micro-holes on the at least one surface of the object using at least one marking unit and generating a two-dimensional data matrix with the array of micro-indents or micro-holes. The two-dimensional data matrix has a plurality of rows and columns. The method further comprises generating a microscale optical code comprising the two-dimensional data matrix and additional four corners. The two-dimensional data matrix represents a binary code matrix of number 1 and 0 in the plurality of rows and columns with each micro-indent or micro-hole forming the binary number 1 and spot with no indent or hole forming binary number 0.

Information is stored in an optical element in the form of a glass or plastic body embodied as spectacles lens, spectacles lens blank or spectacles lens semi-finished product. The information in the form of data is stored on or in the glass or plastic body by creating at least one marking with a marking system. The marking can be read by a reading apparatus. The marking system has an interface for reading information individualizing the optical element. The marking is created permanently by the marking system on or in the optical element at a definition point of a local body-specific coordinate system set by two points on or in the optical element. In this body coordinate system, the manufacturer specifies the position of the lens horizontal and/or the far and/or the near and/or the prism reference point.

An electronic device comprising a semiconductor chip which comprises a plurality of structures formed in the semiconductor chip, wherein the semiconductor chip is a member of a set of semiconductor chips, the set of semiconductor chips comprises a plurality of subsets of semiconductor chips, and the semiconductor chip is a member of only one of the subsets. The plurality of structures of the semiconductor chip includes a set of common structures which is the same for all of the semiconductor chips of the set, and a set of non-common structures, wherein the non-common structures of the semiconductor chip of the subset is different from a non-common circuit of the semiconductor chips in every other subset. At least a first portion of the non-common structures and a first portion of the common structures form a first non-common circuit, wherein the first non--common circuit of the semiconductor chips of each subset is different from a non-common circuit of the semiconductor chips in every other subset. At least a second portion of the non-common structures is adapted to store or generate a first predetermined value which uniquely identifies the first non-common circuit, wherein the first predetermined value is readable from outside the semiconductor chip by automated reading means.
