Necrofancy,

@jonty I see a press release on this by the Hong Kong Monetary Authority:

https://www.hkma.gov.hk/eng/news-and-media/press-releases/2023/10/20231020-4/

"It has recently come to the attention of the Hong Kong Monetary Authority (HKMA) that shredded banknote paperweights sold at the HKMA Information Centre contain pebbles to make them heavier and enhance their function as paperweights. Therefore, the number of shredded banknotes inside each paperweight falls short of the approximate number stated on the paperweight label."

Nici,

@jonty @Nici omg I retooted this without even realizing it was you jonty!

You lent me a lidar sensor at #cccamp23 I havent forgotten about returning it just so you know :)

I'll really wanna make it to emf this year, and assuming that all brit hackers will be there I'll give it back to ya then :)

Thank a bunch, cheers!

@Nici Yay! I was beginning to worry that my faith in the hacker community being lovely people was wrong 😆

No rush! I have no need to get it back quickly - just glad to know who has it.

Do you remember who was with you that borrowed the other one?

@Nici Also, yes, I will definitely be at emf - I'm one of the organisers! 😆

Drop by HQ or call JONT on dect.

Nici,

@jonty

>Do you remember who was with you that borrowed the other one?

Oh man, I dont remember at all. I don't think we exchanged any socials... They should have your email stickered on the sensor though... Mine did.

@Nici Yep it definitely did have a sticker on - well, hope they get in touch one day :D

Archivist,

@jonty oh yeah this one is very good

@jonty Surely they record the serial numbers of notes in circulation and notes removed from circulation? And cashing a defaced note can only be done at the central bank? In which case they’re guaranteed to check the serial number and attempting to cash would raise a few eyebrows.

@jonty dammit- i could’ve used the shredded cash for a project i’ve been working on for over a decade >.<

@jonty This suggests some else came up with this idea first and has been stealing 40% of the notes and making up the weight with stones.

@TomF Given they show that complete notes are in the shreddings it's more likely that the person who shredded them also packed the cylinders and just made off with complete notes tucked into their underpants

GHabiger,

@jonty
So wait ... I think the most interesting fact is actually this:

> This cylinder only contained 82.57/138 = 60% of the shredded
banknote pieces that the label had claimed. Although this issue
is not the focus of this paper, it appears that the Hong Kong
Monetary Authority has broken the law

In other words: Someone stole some bank notes before shredding, then filled the container up with stones to make up for the lost weight?

:D

@GHabiger That was my guess too!

A nice little profit - even the "full" ones were missing 56 notes, which means they were making off with a minimum of $56,000 HKD ($7000 USD) per cylinder!

michaelgemar,

@jonty @nev I’m guessing that sticking the pieces together would not result in a convincing bill…

jonty,
@jonty@chaos.social avatar

@michaelgemar @nev Doesn't need to be convincing - the paper cites The Association of Commercial Banknote Issuers: "banks will only reimburse you with the face value of a damaged banknote if you still have at least half of the banknote and visible serial number".

They might be real mad about it though.
