What Code Do I Need for My Product? (Customer Decision Guide)
Choosing the right barcode format depends on where your product is sold, the packaging substrate, and scanner infrastructure:
What is the difference between static and dynamic amount UPI QR codes?
Static codes leave the amount blank, allowing customers to key in their own total at checkout. Dynamic amount codes embed a fixed rupee figure (e.g. am=450.00) so the amount is locked when scanned.
Can I print UPI QR codes on tabletop acrylic tent stands?
Yes! UniversalCodeMaker exports high-resolution 300 DPI vector SVGs and PNGs that can be printed on durable vinyl or cardboard standees for checkout counters.
NPCI Unified Payments Interface Guidelines
- UniversalCodeMaker is an offline static code generator and is never in the flow of funds. All financial settlement occurs through NPCI member banks.
- Always test-scan your generated QR code with a ₹1 test transaction before printing physical shop signage to verify your VPA spelling.
- Ensure your merchant name matches the official registration on your bank account to avoid customer confusion during payment verification.
Frequently Asked Questions
Which UPI apps can scan and pay with this QR code?
All standard payment apps supporting NPCI specifications can scan this code, including Google Pay, PhonePe, Paytm, BHIM, CRED, Amazon Pay, and all Indian banking apps.
Is there any transaction fee or intermediary involved?
None. UniversalCodeMaker does not process payments or handle funds. The QR code points directly to your Virtual Payment Address (VPA / UPI ID) so 100% of funds go straight into your bank account.
Can I specify a fixed amount or let customers enter their own?
Both options are supported. Leave the amount blank to let the customer enter any amount, or specify a fixed amount to lock the payment to an exact invoice figure.
