Microsoft's HealthVault, the medical records database, is to be integrated with VeriMed's human-embedded RFID tags, allowing doctors to access the medical records of unconscious patients with a quick scan of the arm.

VeriMed consists of an RFID tag that is embedded in the arm of a hopefully willing participant, and responds with a 16-digital identity code when queried at 134KHz. This code can then be used to identify the person through VeriChip's website, and will soon be able to link to their medical records as stored on Microsoft's HealthVault system.

"VeriMed adds an exciting RFID-based option for HealthVault users trying to keep themselves and their families safe," says Sean Nolan, the chief architect for HealthVault, quoted in RFID Journal. If you're excited about the idea of being electronically indexed then this is probably the technology for you.

Not that the future of VeriMed is in any way certain, despite the Microsoft link. The company's parent, VeriChip, has already tried to sell off the human-implanting part of the business as punters prove remarkably reluctant to be serial-numbered. Should the business fail entirely, a connection to HealthVault could be the best hope for the poor souls who've already succumbed to having chips embedded in their arms. ®
