Two-dimensional barcode coding and decoding method including multiple services

The present invention is a two-dimensional barcode encoding and decoding method including multiple services, in particular, when a text string is input, the multi-service text string is segmented by a tag syntax; and when decoding, multiple services are provided. The bar code content is segmented and decoded according to the label format, the actuating button is activated, the bar display is displayed, and the actuating button is pressed according to the user selection to start the service.

Since its invention, 2D barcode technology has been widely used in various fields due to its wide coding range, large message capacity, confidentiality and anti-counterfeiting functions, high reliability and strong data fault tolerance. Common international standard 2D barcodes include PDF417, Data Matrix, MaxiCode and QR Code. In addition to numbers and symbols, some encoding methods can also be added to various languages and languages. In addition, the current development of hardware devices has grown rapidly. And the effective 2D barcode identification scheme makes 2D barcodes one of the most important electronic barcode technologies to be used today.

Because 2D barcodes are easy to use, fast to execute, and have few input errors, they are often used to provide speed dialing, SMS transmission, fast delivery of e-mails, quick link to websites, fast positioning of GPS coordinates, automated text input, and digital content download. Many life and business applications, identity identification and business transactions.

However, the two-dimensional bar code technology used in practice, each bar code can perform a service. When a program needs multiple services, it will need multiple 2D bar codes, and must separately scan, separately identify and decode, and perform corresponding services separately. . Each bar code not only has its own positioning pattern, but also requires multiple actions in operation.

It can be seen that although the two-dimensional bar code technology has many excellent features, there are still many shortcomings in the above-mentioned conventional methods, which is not a good design, and needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally successfully developed a two-dimensional barcode encoding and decoding method containing multiple services.

The object of the present invention is to provide a two-dimensional barcode encoding and decoding method including multiple services, so that a single two-dimensional barcode has the capability of performing multiple services, and the function of simultaneously reading a single barcode can provide multiple service options at the same time, and can save 2D bar code printing area, simplify the use process, provide more convenient and efficient use, change the existing 2D bar code operation habits, make 2D bar code more acceptable to the general public, and widely used in various fields.

A two-dimensional barcode encoding and decoding method comprising multiple services for achieving the above object aims to separate a multi-service text string by a tagged grammar when inputting a text string. After the image processing technology is used to capture the barcode image, the two-dimensional barcode with multiple services is segmented and decoded according to the label format, the activation button is activated, the column display is displayed, and the actuation button is pressed according to the user to start the service. A single 2D barcode has the ability to perform multiple services and is used in a wide variety of applications.

The invention separates the text strings of the plurality of individual services by using the specified special label format when the two-dimensional barcode input is made, and forms the form of the two-dimensional barcode character string 1 including the multiple services as shown in FIG. The two-dimensional barcode text string 1 including multiple services is composed of one or more single service text strings 11 including a label format, and the label format of each single service string 11 except the text string of the service In addition to 112, it may include only the label header 111, or only the label tail 113, or both the label header 111 and the label tail 113. This tag can be composed of single or multiple words, numbers or symbols to facilitate the logic of the decoding program.

The use of the two-dimensional bar code is performed by using an image capturing device such as a photo phone, a PDA or a computer, and the two-dimensional bar code image 21 is first captured by the process of FIG. 2, and then the digits are binarized by the module 22. And the program built in the capture device is used for processing; and when the program is decoded, the tagged multi-service module 24 can be inserted in front of the conventional module 23 for 2D barcode judgment, decoding, display and service startup. The module 23 includes a traditional two-dimensional barcode decoding module 231, a traditional two-dimensional barcode decoding display module 232, and a traditional two-dimensional barcode service startup module 233. The module 24 first determines whether the module 241 is in the format of a two-dimensional barcode character string 1 containing multiple services. If the determination is no, the program performs the traditional decoding, display and start service process of the 23; if the determination is yes, the module 242 decodes the service strings contained in each of the tags and sequentially uses the module 243. Or assign a dedicated activation button to each segment of service, and module 244 displays the actuation button and its corresponding service bar on the screen of the image capture device. The user can press the actuation button to activate the module 245 to perform the service corresponding to the actuation button.

As shown in the embodiment of FIG. 3, in the conventional method, when processing the three services of making a call 31, connecting to the Internet 32, and transmitting the short message 33, the text string must be input three times to create three two-dimensional barcodes with a single service. If you call the phone number 0212345678, you must enter the TEL: 0212345678 text string 311, the link URL www.hinet.net, you must enter the http://www.hinet.net text string 321, send the newsletter to the 0912345678 door number and the newsletter content For me to participate, you must enter SMSTO: 0912345678: I want to participate in the text string 331, to create three two-dimensional barcodes 312, 322, 332. Each of the two-dimensional barcodes has its own positioning pattern, and the user who reads the barcode must also perform the reading operation three times to recognize and execute the service contents 313, 323, and 333 of each two-dimensional barcode.

However, in the embodiment of the present invention, the text string of the three services can be input at the same time, and the label format of the <qrc: service text string string or the TEL:, http://, or SMSTO: tag code is used. The three service content segments are segmented, the text string 411 is entered, and a two-dimensional bar code 412 containing multiple services is created. When the decoding program reads the <qrc: tag header, it parses the service string between the tag header and the tag tail, and then distributes the actuation keys such as numbers 1, 2, and 3 to each segment service; 413. Display the actuation keys and their corresponding screens serving the device in a line. The user can choose to activate the button to perform the desired service. For example, when you press 1, the phone will automatically dial the phone number of 0212345678; when you press 2, the phone will automatically connect to http://www.hinet.net; when you press 3, the phone will send a message to the number 0912345678. The content of the newsletter is I want to participate. The invention can reduce the process that requires multiple barcodes, multiple scans, multiple decodes and service startup in the past to be reduced to one bar code, one scan, one bar display service, and can be actuated according to the user's selection. The key starts its corresponding service. It effectively simplifies the operation process, changes the operating habits of existing 2D barcodes, and improves the convenience of using 2D barcodes.

The manner in which the invention is used will be described below with two application examples to demonstrate its utility.

Application example 1: A sightseeing spot provides a voice navigation system that can connect to the back-end network after the passenger reads the 2D barcode on the mobile phone; and can read the 2D barcode dialing call to the management unit to reflect the problem.

If you use the method of learning, the audio guides of different languages, such as Mandarin, Taiwanese, Hakka, English, Japanese... will have their own designated 2D barcodes, and passengers will need to read them according to their needs. The two-dimensional bar code represented by the language system listens to the navigation information, and can read a specific two-dimensional bar code to immediately dial the phone to react to the relevant unit, so that a plurality of two-dimensional bar codes need to be produced at the same time, and the bar code is easy to read.

However, if the present invention is used, the same two-dimensional barcode can be shared by the telephone numbers of the national, Taiwanese, English, English, Japanese, and the various language systems. After the passenger reads the 2D barcode on the mobile phone, according to the representative number of each language, press the 1, 2, 3, ... button to connect to the backend network to listen to the corresponding audio guide information or dial the call immediately. The phone responds to the relevant unit, which is convenient and not easy to produce errors.

Application example 2: A city holds a hand ticket to choose a city lady. Let the public read the 2D barcode represented by each candidate on the mobile phone and send a newsletter to indicate the supported objects; and the 2D barcode can be read to link the website of the voting statistics.

In the conventional method, each candidate will have their own representative 2D barcode. The public will read the individual 2D barcode by mobile phone and send the SMS to express the supported objects, or read the specific 2D barcode to link the voting results. The website, therefore, will need to print multiple 2D barcodes at the same time, and it is easy to read the wrong barcode.

However, if the invention is used, only one two-dimensional barcode is needed, and the public only needs to read the two-dimensional barcode once, and according to the candidate representative number, press the 1, 2, 3, ... button to transmit. The newsletter goes to the counting platform or immediately checks the voting results.

Through the above application examples, it is found that the present invention can integrate the services of multiple two-dimensional barcodes into a single two-dimensional barcode with multiple service functions, and share the positioning pattern, thereby effectively saving the number of two-dimensional barcodes and the printing area. The ability to make a single 2D barcode with multiple services, the ability to read a single barcode at a time can provide multiple service options at the same time, and is not prone to errors, and has its unique and practical advantages.

The two-dimensional barcode coding and decoding method comprising the multiple services proposed by the invention has the following advantages when compared with other conventional technologies:

1. The invention can integrate the services of a plurality of two-dimensional barcodes into a single two-dimensional barcode with multiple service functions, and share the positioning pattern, thereby effectively saving the printing area of the two-dimensional barcode.

2. The invention can make the two-dimensional barcode have the capability of multiple services, and can realize the function of simultaneously providing a plurality of service options by reading a single barcode at a time, simplifying the use process, providing a more convenient and efficient use manner, and changing the existing two-dimensional barcode. Operating habits make 2D barcodes more acceptable to the general public.
