Dear Hiring Manager, I can implement secure device fingerprinting on your Hosted Payment Page using HMAC-SHA256 to protect sensitive payment and transaction data. I will share my previous work and portfolio after the chat initiation. Implementation approach: * Generate device fingerprint server-side using HMAC-SHA256 with merchant transaction password as the secret key. * Hash required fields (vendor\_name, payment\_reference, payment\_alert, unit\_names, unit\_prices) in the defined order with pipe separators. * Exclude computed values from form submission, sending only the fingerprint as a hidden field. * Ensure compliance with PCI-DSS standards and test across multiple browsers/devices. Queries: * Which server-side technology is your payment page currently using? * Do you need additional anti-fraud measures like IP/geolocation checks? * Should the fingerprint validation be logged for audit purposes? I will be looking forward to hearing from you. Kindest Regards,
