All banknotes to have a 2D barcode?

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.

The bad would drive out the good?

Any instance of creating uncertainty or doubt is bad for a currency, modern
currencies are supported by nothing other than trust, they are merely bits
of paper to which the general public attribute 'value'. There is the
conceit, is a stolen note any different to what the BoE prints for itself
above the growth rate of the economy? Money supply in general is in double
digits year on year, we all pay for this hidden inflation eventually,
regardless of its source.
