How to add QR codes in PDF invoices for UPI payments.

What are QR codes?

Quick Response (QR) codes are the modern evolution of traditional barcodes. They store data in a grid of black-and-white squares that can be scanned by a smartphone or other devices. While they’re often used to link to websites, QR codes can also contain information like email addresses, phone numbers, payment links, or even event details, making them a fast, flexible way to share data instantly.

Why should I add QR codes to PDF invoices?

QR code payments have become a cornerstone of India’s digital payment landscape. They are an integral part of the Unified Payments Interface (UPI) system because they power the countless of daily transactions between businesses and customers across the country.

By adding a UPI QR code to your PDF invoices, you:

• Accelerate payments: Customers can scan the QR code with their mobile phones and pay instantly through UPI apps like Google Pay, PhonePe, or Paytm.

• Reduce errors: Customers can avoid the manual entry of UPI IDs or bank details, which is already tedious in the first place.

• Project professionalism: QR codes are not just a design upgrade. They make your invoices look modern, trustworthy, and tech-savvy.

• Ensure secure transactions: UPI QR codes are linked to verified accounts and payment information is encrypted during transactions to make sure no personal data is compromised.

How to create a QR code for PDF files.

Before embedding the QR code in your invoice, you’ll need to generate one. Follow these easy steps:

1. Open your preferred UPI application.

   There are many reliable options available: Google Play, BHIM (Bharat Interface for Money), Amazon Pay UPI, CRED, PhonePe, and more.

2. Navigate to the QR section.

   Once there, enter your UPI ID or payment link. Input the payment amount if you’re requesting a fixed amount or leave it blank to give customers the liberty to enter the amount themselves.

3. Generate the QR code.

   Tap the “Generate” button and download the QR code image. Save it as a PNG or JPG file for high-quality printing or embedding.

4. Test the QR Code

   Use a UPI app to scan the code and verify that it opens the correct payment page.

Online QR generators such as Adobe Express free QR generator can also be used for this. For example, you can enter a custom URL, generate a QR code, and even customise the style and colour of the image to fit your branding.
