News agency Reuters have reported that scientists in America have developed a ‘nano’ QR Code printed from fluorescent ink which can be used to help prevent counterfeiting. The basic idea is that the QR Codes, invisibly to the naked eye, are printed on the bank notes so they can be checked for authenticity later. Many people may ask why QR Codes? Bank notes have had invisible ink used to track them for years! Well QR Codes can contain far more information, and this information can be linked to a database which means without access to the database it will mean nothing to those attempting replication. Secondly they can be printed so small that they could be made to only be visible through a microscope, again making the job of any potential counterfeiters much harder.
Barcodes, in their simplicity are the ideal solution. The price to print them is only ever as much as the ink, compared to NFC chips which are less versatile. It is for this reason that it will be a very long time until we see them out of use, in fact it appears uses for barcodes are forever expanding.
