Description
Technical Field
The invention relates to the field of information communication, in particular to a bidirectional communication method in a code scanning process.
Background
People are increasingly using two-dimensional codes or bar codes on mobile phones to transfer information. Such as completing payment using a bar code or two-dimensional code on a cell phone; and displaying the two-dimension code to the gate to acquire the passing authority and the like.
However, in the current code scanning process, information transmission is generally unidirectional, and only can be transmitted to the scanning device through the mobile phone, but not can be transmitted to the mobile phone through the scanning device. The one-way transmission of information brings inconvenience in some scenarios, for example, when mobile payment is performed in a place with poor signal, the merchant device may not know the payment result under the weak network condition, and further disputes may be caused. If the mobile phone and the code scanning device can communicate with each other, some means such as information encryption, authentication and the like can be combined to mutually transmit payment results, so that single-off-line or double-off-line transaction is realized.
For another example, in a scene where the two-dimensional code contains more contents, the two-dimensional code contents are denser. Under the present one-way communication condition, the code scanning device is required to identify the whole complex two-dimensional code at one time, so that the identification difficulty is increased, and the identification rate of the two-dimensional code is reduced. If two-way communication is available, more contents can be put into a plurality of two-dimensional codes, so that one complex (dense pattern) two-dimensional code is converted into a plurality of simple (sparse pattern) two-dimensional codes, information of the mobile phone is fed back after the code scanning equipment identifies one code, and the mobile phone displays the next code. And the recognition of more contents is realized in a mode of breaking up the whole into parts.
In the prior art, two parties are connected through an additionally-arranged online server, but under the condition that one party is not in a network, the code scanning equipment cannot transmit information to a mobile phone.

Example 1
As shown in fig. 1-3, the present invention provides a method for bidirectional communication during code scanning, comprising the following steps:
s1, emitting visible light or invisible light (invisible to naked eyes, but visible to a front camera or a light sensor of a mobile phone) by a code scanning device through adding an optical signal module or using an existing optical signal module, and controlling the module to be turned on and off to manufacture stroboflash;
s2, capturing the stroboscopic change by the mobile phone through a light sensor or a front camera, converting the stroboscopic change into digital information and processing the digital information, and transmitting information from the code scanning equipment to the mobile phone in such a way;
s3, the scanned mobile phone displays the two-dimensional code or the bar code to the code scanning equipment, when the codes are identified by the code scanning equipment, the code scanning equipment can encode the feedback information according to a certain encoding mode (such as Morse code and the like), then a light source switch on the code scanning equipment is controlled to perform corresponding on-off operation, and a converted optical signal is sent out;
and S4, after the light ray change is captured by the sweeping mobile phone, the light ray change information is decoded, and then the transmitted information is restored for processing.
Specifically, the scanned mobile phone displays the two-dimensional code or the bar code to the code scanning device, when the codes are identified by the code scanning device, the code scanning device can encode the feedback information according to a certain encoding mode (such as morse code and the like), and then controls a light source switch on the code scanning device to perform corresponding on-off operation, so as to send out a converted optical signal.
