RapID Tags are humane, automated, mini-eartags providing fast and accurate identification for lab animals. The hardened 2-D barcode scans instantly with 100% accuracy providing millions of unique IDs. Multiple colors allow immediate secondary (visual) identification without scanning. RapID Tags are totally MRI and autoclave compatible, and are minimally invasive (no surgery required). RapID Tags are the new, cost-effective, smart solution for automated lab animal identification.
