Problems solved by technology

However, this requires a camera with an infrared laser installed on the smartphone or the merchant provides an infrared laser scanning device
As a result, the universality of application and promotion is greatly reduced, and if it is visible with infrared laser irradiation, it also leads to security loopholes

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with specific embodiments.

[0022] A method for reading an invisible touch code label includes a touch code label with a barcode or two-dimensional code printed on the surface and a touch code reading device. The touch code reading device in this embodiment adopts a smart phone equipped with a multi-touch capacitive screen, The barcode or two-dimensional code is printed with conductive material, the smart phone system is installed with touch code reading software (touch code reader), and the multi-touch capacitive screen of the capacitive touch screen mobile phone is used to communicate with the Touch the barcode or QR code on the code label directly, and read the barcode or QR code directly.

[0023] At present, the multi-touch capacitive screen is used to touch the surface of the screen with a finger. The surface of the screen and the finger form a coupling capacitance. Because a high-freq...

Abstract

A stealth touch code tag reading method comprises a touch code tag with a bar code or a two-dimensional code printed on the surface and a touch code reading device, and the bar code or the two-dimensional code is printed by a conductive material; a touch code reader is run on the touch code reading device; the touch code tag is contacted with a multipoint touch-control capacitance screen which is installed on the touch code reading device; the multipoint touch-control capacitance screen transmits the read bar-code or two-dimensional code information to an operation processor of the touch code reading device to be calculated; the operation processor which is embedded inside the touch code reading device is controlled to execute corresponding action instructions according to the calculation result; and the multipoint touch-control capacitance screen of the touch code reading device is directly contacted with the bar code or the two-dimensional code on the touch code tag, and the multipoint touch-control capacitance screen recognizes and reads the bar code or the two-dimensional code, so that simpleness in operation is achieved, the time is saved, and the user population can be enlarged; and the scanning can be completed by utilizing the existing device with the multipoint touch-control capacitance screen, so that no additional cost is needed, and convenience in popularization and application can be realized.

Description

technical field [0001] The invention relates to a method for reading barcodes and two-dimensional codes, in particular to a method for reading invisible touch code labels for reading invisible barcodes and invisible two-dimensional codes printed on commodities or labels. Background technique [0002] At present, QR codes have been widely used in all walks of life and people's daily life. This QR code can be quickly read by a reader with a camera. Compared with the previous barcodes, QR codes can store richer information. , including encryption of text, URL addresses, and other types of data. In 1994, Denso Wave, a subsidiary of Japan's Toyota, first invented and used QR codes, leading the trend of QR codes in Japan and South Korea. Later, European and American countries also began to use QR codes in large numbers. But QR codes still face their own problems and challenges from the outside world. First of all, from the perspective of ordinary users, there are still many user...
