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.

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

RDIF tags? Have never heard of them. Could you elaborate?

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.)

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.

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.

Do you mean RFID tags?

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.

How would the general public check notes given in change, or from
cashback transactions, or even from a bank's cash machine?
