Linking a QR Code Scanner to a Database

If you want to know an example on how to link a QR code scanner to a database. Say you have built the “QR Code Scanner” application. The main idea of this database is that users can easily scan QR codes via a mobile device and then search database tables for records containing QR codes.

For instance your database keeps descriptions and photos of different computer parts. Each part has a unique QR code. There are parts of two types: Type A and Type B, so you keep these types in two separate tables:

 

So, each user should be able to scan a particular part’s QR code to search the database for this component and get all the supplemental information related to this part.

 

How do I connect QR code to database?

Click on the QR code icon to begin scanning for link QR code to database. When the scan is complete, the text will appear in the “QR Code” field. Use the “Send” icon to submit the record. As a result, the request will be sent to the database and a new record containing QR code value will be created in the “Search Requests” table.

 

Linking a QR Code to an Online Database Entry

I will have a series of printed documents with QR codes on them (one code on each document).  These documents will be distributed to people, and I want the person who scans a given QR code to be taken to a database entry (database currently existing in Excel) that corresponds to the URL that the QR code produces.  It’s really that simple.  The database entry will have seven or eight variables that will have been previously generated: when the QR code is scanned, the person doing the scanning should be able to see what the database entry is for that QR code, hopefully presented in a visually pleasing format.  There is no need for visitors to change the data in the database, nor to add to it: I will manage the contents of the database, I just need visitors to be able to find their “page”.

The database will be hosted on a friend’s server.  I know the server’s URL, but am unsure how to place my Excel database on it nor how to arrange things so that the server can display the results of a QR code database scan event.

What would you have to setup in your database to build this functionality?

1.Generated Document

In this example each table contains a generated document that keeps all the data related to the part. For instance, “Document A” can be generated in the “Type A Parts” table.

“Document B” can be generated in the “Type B Parts” table.

 

2.Auxiliary Formula-Text column

Moreover, you need to add a “RecordId” auxiliary formula-text column to each table with the following formula: RecordId().

So, let’s create the “RecordId” formula-text column in the “Type A Part” table:

Also, you should create the same column in the “Type B Part” table:

These columns will be used in the future adjustment.

3.New “Search Requests” table

Now you need to create a new auxiliary table. Let’s name it “Search Requests”. This table should include the following columns: QR Code, Document, RecordIdA , RecordIdB, DocumentA, DocumentB.
