What a Custom Payment QR Generator gives you
Using a Custom Payment QR Generator you can produce a clean, shareable image that encodes:
- Payment address / UPI ID or other payment handle.
- Optional amount so customers don’t have to type it.
- Optional payee name and description/note to help customers confirm details.
- A single downloadable PNG (or shareable file) that works with popular Indian payment apps.
This is perfect for in-person sales, invoices, social media posts, small events, or sending a quick payment request.
When to use it
- At a kiosk or shop counter for fast, contactless payments.
- When sending payment requests over chat or email.
- For social selling (WhatsApp, Instagram) where buyers need a simple tap-to-pay option.
- When issuing invoices, receipts, or donation links.
- For events, stalls, or roadside sales where a printed QR is convenient.
How to prepare payment details (what to fill in)

Most Custom Payment QR Generators ask for a few simple fields. Fill them carefully:
- Payment method: Choose UPI, Paytm, PhonePe, Google Pay, bank transfer, etc.
- Payment address / UPI ID: Your merchant UPI ID (example: merchant@bank). For non-UPI methods use the exact payment handle required by that app.
- Recipient name (optional): Helps customers confirm they are paying the right person.
- Amount (optional but helpful): Fix the amount for single-price items, or leave blank for flexible payments.
- Description / note: A short message shown to the payer (invoice number, order id, purpose). Keep it concise.
When the QR is scanned, most UPI apps will auto-fill these fields (if the generator included them), and the payer only needs to confirm.

Best practices for printing and sharing QR codes
- Use high contrast: Black-on-white QR images scan best. Avoid busy backgrounds or placing the QR over colorful patterns.
- Maintain quiet zone: Keep a clear white margin around the QR (no text or logos touching the edges).
- Size matters: For printed receipts or posters, keep the QR at least 4–5 cm (≈1.5–2 in) wide for easy scanning. Digital images for chat can be smaller but still readable.
- PNG preferred: Export as PNG for lossless quality; avoid heavy JPEG compression which can corrupt QR modules.
- Add context: Place a short label like “Scan to Pay — UPI / Paytm / PhonePe” and include the payee name so people trust the code.
- Add fallback text: Show the UPI ID or payment address below the QR so users can type it manually if scanning fails.
- Print test: Always test-scan the printed QR using multiple phones and apps before distributing.
Security and safety tips
- Do not embed sensitive personal data. Only include the payment handle and benign notes. Never encode full bank account details or personal IDs in ways that can be misused.
- Verify before sharing publicly. Make sure the encoded payment address is correct — small typos can route money to the wrong recipient.
- Avoid public exposure of changing links. If you expect many different invoices, generate unique QR codes per invoice rather than reusing the same one openly.
- Label QR codes clearly. Scammers sometimes swap QR images — clear branding and payee name reduce risk.
- Educate staff and customers. Encourage customers to check the payee name shown in their app before confirming payment.
Limitations to keep in mind
- QR is only a pointer. For UPI QR codes, the payment still requires confirmation in the payer’s banking/UPI app.
- Amount field may be editable. Some apps allow the payer to change the pre-filled amount — don’t rely on it for strict, uneditable payment capture.
- App compatibility varies slightly. Most major Indian payment apps read standard UPI QR information, but always test across apps your customers use.
- Bank transfer support differs. If using bank details instead of UPI, some apps won’t auto-populate fields from a QR.
Troubleshooting common scan problems
- QR won’t scan: Check contrast, size, and quiet zone; increase size or re-export at higher resolution.
- Blurry or pixelated image: Re-export as PNG at a larger pixel size or reprint at a higher DPI.
- App shows wrong payee name: The name displayed comes from the payer’s app database for that UPI ID — confirm the UPI ID is correct.
- Amount not populated: Ensure the generator included the amount field; some wallets ignore optional parameters.
- Scanner reads garbage: If QR contains newline or unexpected characters, regenerate with a cleaned payment string and test again.
Quick FAQ
Q: Can I use the same QR for multiple customers?
A: Yes — for general payments (like donations or store counters) reuse is fine. For invoices, generate one per invoice to reduce confusion.
Q: Is it safe to post QR codes on social media?
A: You can, but be careful: anyone who scans it can attempt to pay. For one-time requests, consider generating a fresh QR per invoice.
Q: What if a customer’s app doesn’t accept the QR?
A: Offer the UPI ID as fallback text or a manual payment option.
Conclusion
A Custom Payment QR Generator is a practical, low-friction way to accept digital payments in India. Fill in accurate payment details, export a high-contrast PNG, test on multiple devices, and follow the safety tips above. When used responsibly — with clear labeling and periodic regeneration for invoices — QR payments make collecting money fast, professional, and customer-friendly.
