Thats a good point, currently, with todays technology and changes to bank notes, it wouldn't be hard to take a photo of all the bank notes in someone's purse and wallet showing the bank notes serial number when it enters someone's possession.
It will certainly reducing muggings and thefts if this activity took place.
That image and bank note serial number can then be uploaded to a central, database where bank notes in various currency's can be geolocated and its movements tracked. You device and smartphone can equally form a distributed blockchain database by having your device share the data with those devices around them.
When a bank note leaves someone's possession, the app can be notified of a possession change where the currency then enter's a dark web like state unless the bank note movement is into the possession of someone else using said app.
Whether the banks and currency printers want to get on board with such idea in order to complete the introduction and retirement of bank notes in order to help build confidence in the currency, remains to be seen.
Of course, if banks and currency printers dont want to get onboard with this public track and trace of the public's currency, then are they reducing confidence in the currency, in effect weakening or expiring the currency just like we see in this white paper and in China crypto currency experiments.
Afterall, no one person can track and trace the bank notes that pass through their hands, we dont know just how bad counterfeiting of bank notes is. With todays tech, namely smartphones and an app, it would be possible to restore even increase confidence in a currency in a totally passive aggressive way!
This would also be a way to decentralise existing currency's in todays form, as this app and photo of the bank serial numbers is like cryptocurrency miners and every photo becomes an entry in a Blockchain which would make it hard for any AI to replicate and highlight any physical currency counterfeiters.
In other words, the public could become the pseudo cryptocurrency miners, and their participation would strengthen the currency they use. This way, the many benefits cited by the central planners like the Blank of England as done here, can be applied within days of this idea being made public.
How quickly could you undermine other currency's like the Dollar or Euro if a population were to suddenly adopt this change of behaviour?
Most people only ever have in their possession a fraction of the bank notes supposedly in circulation, and these officially circulated bank notes are only a fraction of the total money that exists in a currency. If you are familiar with this infographic https://traversals.com/blog/surface-web/ you should understand that the serial number on your bank note is just the Surface Web, and that banks and central planners are the dark web!
No one has a bank account which shows the bank note serial numbers entering or leaving your possession and no currency provides a means to currently track and trace all currency! Arguably its one giant fraud operating in plain sight!
