Nov. 8, 2005 – Singapore-based nanotechnology spin-off Singular ID is to supply its magnetic protection tags to the Singapore subsidiary of automotive parts manufacturer Sanden International. The tags contain micro- and nanometer sized magnetic components that create a unique magnetic signature, but are fairly expensive and pose some problems when operating in metallic environments.
Other marking technologies such as shot peening and laser etching can generate two-dimensional barcodes, but they are relatively difficult to reproduce. Singular ID is backed by U.S.-based Advance Nanotech.
