Creating Your QR Code Attendance System

Why Use a QR Code Attendance System?

  • Accuracy: Automated data capture eliminates manual errors and ensures accurate attendance records.
  • Security: Unique QR codes for each student prevent fraudulent check-ins.
  • Cost-Effective: This method utilizes free or low-cost tools, making it accessible to any classroom.
  • Efficiency: Teachers save time and can focus on instruction rather than administrative tasks.

This solution will allow teachers and educators to take advantage of a quick and secure classroom attendance system.

Step 1: Generating QR Codes with Google Slides

The first step involves creating student ID cards with unique QR codes.

Google Slides provides a simple and free platform to design these IDs.

  1. Create a New presentation: Open Google Slides by going to slides.new.
  2. Customize Page Setup: Navigate to File > Page Setup. Select "Custom" and set the Dimensions to match a typical smartphone screen (e.g., 6.5 cm x 15.5 cm). This ensures that the ID card is easily viewable on a phone.
  3. Design the Student ID: Design a template, for example, add your school logo or school board details. You can include placeholders for student photos, names, and an expiry date. Use double curly brackets {{ }} to denote these placeholders. For example, {{Image}} for the student's photo, {{FirstName}} {{LastName}} for the name, and {{ExpiryDate}} for the validity period.
  4. Add a QR Code Placeholder: Insert another image placeholder and label it {{QRCode}}. This is where a unique QR code will be generated for each student.
  5. Save the ID Card Template: Name your Google Slides presentation something descriptive like "Student ID Cards."
  6. We highly suggest setting up a size similar to what you might find on a cell phone. This means you are working vertically

Step 2: Setting Up Your Data in Google Sheets

Now you are going to setup google sheets, this will enable a good backend setup of data, here are the steps.

  1. Create a New Google Sheet: Open Google Sheets by going to sheets.new. Name it something descriptive like "Attendance Data".
  2. Set Up Column Headers: Create columns for the following data points that match your template for the student ID card in google slide: StudentID, FirstName, LastName, DateOfBirth, Photo, Program, ExpiryDate, and importantly, QRCode

    . You can add more columns, if your student ID card includes them.

  3. Populate Student Data: Fill the rows with the Relevant information for each student. For the "Photo" column, insert the shareable Google Drive link of each student's photo.
  4. Generate QR Codes:
    • Navigate to Extensions > Add-ons > Get add-ons.
    • Search for and install the "Document Studio" add-on by Digital Inspiration.
    • After installation, navigate to Extensions > Document Studio > Open
    • In the QRCode column, enter the formula =QRCODE(StudentID) . This will generate a QR code based on each student's unique ID, that the system can use.
    • If it still doesn't come up, type =QRCODE to find that the document has been added.

Step 3: Automating the Attendance System with AppSheet

AppSheet will be used to scan your system with your phone, it can make your attendance system efficient.

  1. Create an App from Google Sheets: In your "Attendance Data" Google Sheet, go to Extensions > AppSheet > Create an app

    . AppSheet will automatically generate a basic app based on your spreadsheet data.

    • In the AppSheet editor, navigate to Data. If you do not already have your excel document linked to AppSheet, press the + Add data Button. To connect to your Google Sheet. The scanner must be setup before the student table is set up .
    • Create two tabels: Scanner and Students . For the scanned data that has been put into the scanner sheet.

    • If you want to have a separate list based on different classes or something like that, it is also possible.
    • In scanner for data type, select all the data and show to prevent people from changing. The exception is the field that contains the student id, which you will need to check. This requires you to enable the scanner.
  3. Configure the Scanner: In the AppSheet editor, navigate to Views. Change to a form by selecting “form” in the View type and use Scanner to connect from excel.
