Counterfeiters, beware! Scientists are reporting the development of a new type of inexpensive barcode that, when added to documents or currency, could foil attempts at making forgeries. Although the tags are easy for researchers to make, they still require ingredients you can't exactly find at the local hardware store. Their report appears in the Journal of the American Chemical Society.
