A method for anti-counterfeit inspection of a QR code of an agricultural product based on a watermark library. The method includes establishing a watermark-containing QR code library; tracing a QR code watermark image; and verifying the QR code watermark image. Watermark-containing QR codes are generated by a QR code generation module and a watermark library, and the watermark-containing QR codes are constructed as the watermark-containing QR code library. The watermark-containing QR code library is used to verify the QR code watermark image, and the QR code watermark image is obtained by tracing the watermark-containing QR codes. In the method for anti-counterfeit inspection of a QR code of an agricultural product based on a watermark library, an image watermark library is designed, so that the embedding of a watermark is no longer single.

A server is used to receive a barcode generation request sent by an end-user device. The server is used to generate, based on the barcode generation request, at least two pieces of barcode information by using at least two code systems, respectively. The server is used to transmit a barcode generation response to the end-user device, where the barcode generation response includes the at least two pieces of barcode information, where the barcode generation response causes an application running on the end-user device to display on the end-user device, alternately, a respective barcode image corresponding to each piece of the at least two pieces of barcode information.

The purpose of the present invention is to provide a system which, in a product delivery procedure, monitors and manages, more simply and reliably, a deviation from a managed temperature during shipment. To solve the problem, provided is a logistics system, comprising: an information reading and transmitting device which reads an information code which is provided on a product and transmits data which is included in the information code; a server which accumulates, via a communications network, the data which is transmitted from the information reading and transmitting device; and a terminal device which refers to the data which is accumulated in the server via the communications network. The information code is formed from a pattern which changes with an occurrence of a deviation from a specified temperature. The system employs the information code.

Methods and apparatus to identify additively manufactured parts are disclosed. An example apparatus includes a body, formed of layers layered substantially parallel to a base layer, composed of a first material having a first density, a first indicium embedded internally in the body as a void, and a second indicium on an external surface of the body, the second indicium aligning with the first indicium.

One embodiment of the invention provides for making electronic payments by scanning a merchant 2D code located near the point of sale with the customer's cell phone and transmitting the code or data embodied by the code to a payment center where the merchant's account can be credited and the customer's account debited without transmitting account information over the airwaves. In another embodiment of the invention, both parties transmit the same randomly generated 2D code or data embodied by the code to the payment center where they are matched to each other and to the buyer and seller to process the transaction. In a further embodiment of the invention, an inked tattoo or barcode marking is employed as a password to authorize access to smartphone applications for example, to make an electronic payment over a threshold amount.

An apparatus for marking a component by applying readable identifying information is provided. The identifying information has at least one identifying feature, in particular an identifying symbol. The apparatus includes a detection device which is designed to detect, on the basis of an eddy current measurement, identifying information applied or to be applied to a component by way of the apparatus.

Methods, systems, and apparatus for combining preprinted information together with coded sensor information within a two-dimensional barcode. The sensor information may be of an environmental, physical or biological nature, and records a cumulative change in status of the environmental or biological condition to which the labeled product has been exposed. A sensor dye chemistry is employed that undergoes a continuous chemical or physical state change in response to the occurrence of the environmental condition. The continuous change is between an initial state and an end state causing a change in the color state of the sensor dye embedded within the sensor-augmented two-dimensional barcode, encoding sensor digital information. Sensor information is recovered utilizing the error-correction feature during barcode decoding.

A method of applying labels to a store shelf in a retail environment. The method includes applying labels with adhesive strips applied to a bottom surface of each label and a top laminate layer with a release coating applied to the top surface of each label. The labels in the pad are sequenced according to a store's planogram.

A flexible sensor label including a reservoir chamber configured to store an activation medium. The flexible sensor label includes an irreversible chamber configured to store a first indicator medium. The first indicator medium is altered in response to the activation medium being released and the flexible sensor label being exposed to a first condition associated with the first indicator medium. The flexible sensor label includes a reversible chamber configured to store a second indicator medium. The second indicator medium is altered in response to the activation medium being released and the flexible sensor label being exposed to a second condition associated with the second indicator medium.

A device and system for providing identification and medical information are disclosed. The device includes a readable code that contains medical biographical information of the subject, a programmable reporter element that is programmed to electronically store at least one particular event relating to the subject, and a signal producing element functionally related to the programmable reporter element. The system includes collecting and storing medical biographical information of a subject, embedding the medical biographical information in a readable code of the device, and scanning the readable code of the device worn by or in the possession of the subject using an appliance to retrieve the medical biographical information of the subject. The medical biographical information allows medical professionals to obtain the subject's medical information in order to provide medical care. Also disclosed is an integrated system for alerting subjects to upcoming events related to their continued care.
