All banknotes to have a 2D barcode?
Hi,
As an interim step to total electronicization of money I believe that 2D barcodes on banknotes should uniquely sign the note, so any imaging network device could tell if the bit of paper was a duplicate, and help tracking. A non-networked device should be able to check the signature, but not do real-time tracking. If your money was stolen you should be able to receive your stolen property when it was handed into a bank. (Or is ownership of banknotes lost upon theft? - uk.legal) 2D barcode technology is well developed and used for example in franking machines. There may be reasons why not to introduce the technology such as to let dollar bills be the currency of corruption. Dave. |

Sorry, I just thought that RDIF tags could have a similar function- if they could be given a unique signiature. |

The proper acronym is probably "RFID", standing for Radio Frequency IDentification. These are small rice-sized units which are surrounded by a flat coil antenna. I don't know if bills could hold them or not, though it's theoretically possible. Cards can hold them easily; I've got one now for access into my workplace, for example. By construction all RFID tags should have a unique code. (Admittedly, there's no real simple way to verify this.) The plan is to tag everything in a warehouse or store with such a tag, which would simplify inventory control. It also leads to some interesting and rather troubling questions -- such as how does one really know that the RFID sitting in one's shirt has been truly deactivated? (Assuming the RFID's in the actual *shirt*, as opposed to the plastic ink-protector unit designed to spray ink all over the fabric if removed without the special tool.) -- #191, It's still legal to go .sigless. |

RFID tags cost around 5 cents and are not very flexible mechanically. What's wrong with the free barcode. john2 |

What's wrong with the free barcode. john2 I suspect there may be hidden codes in banknotes, but you probably need specialist scanning equipment and analysis software. But then again the whole idea of a note is based on confidence, so it may not be needed. |

(Or is ownership of banknotes lost upon theft? - uk.legal) In principle, there is nothing to stop you writing down the serial nos of all your bank notes in case they are stolen. Nobody does, though. Whilst bar codes would make it easier, I am sure that OCR technology can easily cope with reading existing serial nos. There are good reasons for not confiscating money from an innocent end user simply because the serial no is on a list of stolen notes. There are still nearly 30 million pounds of stolen notes missing from the big robbery in Essex a few months go, and that's just one robbery. The grand total must be much higher. Commerce would grind to a halt if everybody had to check each note against a database of stolen ones. |
