Lehigh Valley Health Network (LVHN) in the US is using infrared technology to scan the veins in patients' hands and link the image to barcoded medical records.
LVHN is using the biometric technology to streamline check-in and combat medical identity theft, according to mcall.com.
After the patient is enrolled in the network, staff scan vein patterns in the palms of patients and details are recorded so that they can be easily identified if they get admitted into the emergency room at a later date.
About 1,500 patients have already enrolled as part of the pilot programme.
The system can also help reduce duplicate medical record keeping.
The PatientSecure Biometric Identification System has been developed by Fujitsu Computer Products.
