Palm-based Biometric System for Seamless Patient Registration

Headquartered in the United States, the client is a leading integrated academic health system operating multiple inpatient and outpatient facilities across several regions. With a workforce of over 40,000 healthcare professionals, educators, and researchers, the organization advances patient care, clinical research, and medical education through technology-driven innovation.

• Long queues during peak hours due to manual ID verification and appointment lookups.
• High administrative burden on front-office staff managing repetitive, low-value tasks.
• Risk of human errors during manual data entry into the EHR.
• Lack of a contactless, compliant solution to enhance efficiency and patient trust.

We developed a secure, event-driven system integrating palm-based biometric verification with EHRs to automate patient identification and check-in.

• Patients register once through a mobile app linked to a trusted third-party identity provider that handles authentication only.
• During subsequent visits, palm scans instantly trigger automated workflows that retrieve or deregister patient data securely in the EHR.
• All payloads are fully encrypted and processed via AWS services, ensuring privacy, compliance, and operational transparency.
• The serverless design ensures scalability and fault tolerance without maintaining continuous infrastructure.

• Event-driven integration using Amazon EventBridge, AWS Lambda, and Amazon SQS
• Secure data encryption with AWS Key Management Service (KMS)
• HL7 standard compliance for seamless data interoperability
• Serverless background processes for cost-efficient scalability
• Built-in fault tolerance with dedicated failure queues and real-time monitoring through CloudWatch and AWS X-Ray
  

• 60% faster check-ins, reducing patient wait times from 2–3 minutes to under a minute.
• Lower front-office workload, allowing staff to focus on patient interaction.
• Improved data accuracy, minimizing manual errors in EHR entries.
• Enhanced privacy and compliance, with no personal data stored and all transmissions encrypted.
• Scalable, event-driven foundation ready to support expansion across multiple healthcare facilities.
