Since we launched Google Goggles in 2009, the team has been busy expanding the number of images that can be recognized in categories like book covers, logos and works of art—even partnering with world-class art museums like the Getty Museum and Metropolitan Museum of Art

We've been at work adding new categories of objects that Goggles can recognize, like Sudoku puzzles and, starting today, currency notes. Now, when you point Google Goggles at a banknote you'll get a result telling you the type of bill you're looking at, including the country, denomination and the year.

We've enabled currency recognition for more than 45,000 different types of currency from 300+ countries, including some outdated currencies that are no longer in circulation, like the Italian lira and French franc. We hope this is helpful to travelers and any budding numismatists out there!

But can it tell us whether it's counterfeit or not? ;)
I love cash, but telling the difference between a $1 and a $50 was way too hard!
This is very amazing and the app has many uses that have yet to be investigated. 
+M Hardy i offer you 100 hours of testing ,,,,,,, if you need my services ...........
discussed this post with 1 person in a hangout.
This would be a great feature for the sight impaired. Keeps them from getting ripped off.
+Andrew Bates I'm sure they'll get it right, I just think this can be useful. I've been using Goggles since it came out for Android and it has come a long way.
+Sylvester Johnson I understand that, my comment was more as a response to +Jorge Savoff saying that it could be used to verify denominations for sight impaired.

Google Goggles is a very fun gadget-app.
+Jorge Savoff i had the same thought a few weeks ago. As long as the results can be spoken (accessible options turned on), goggles actually recognized a crumpled bill in less-than-great light.

If I could post a link from the g+ mobile client I would, I'll do so later (it's a post on my g+ stream).


The crinkled US$5 sitting on a wooden bar top with bad lighting was correctly identified (maybe it was a fluke, I was still impressed).

The first shot I took of a prettier US$1. I was wondering if sight-impaired people could use this to id bills...
+Sylvester Johnson again, it's not really a slur on what you guys are doing.

This is like the face-unlock feature on ICS all over again!
I just downloaded Google Goggles and tried to identify a foreign coin I've had since July '11, but I received no matching results. 
Love Google Goggles. Cant wait to see what they come out with next.
Just tried it with a canadian and an american bill works like a charm
That's great! Tourists will love Goggles in Hong Kong. We have three note issuing banks and each of them changes the design once every several years. I can't tell how many different $20 bills we have, but there are at least six.

And Goggle should speak up too. It will be helpful to the visually impaired. Some countries still have the annoying practice of print bills of exactly the same size for all denominations.

But I was too optimistic. I just give it four different $100 notes (I've told you we have lots of different designs). One got it right. One says it is a $20 note. One says it is a $50 note. One isn't recognized as a banknote.
IT MIGHT BE A BIG HELP if you mention to the people looking at these bills, that all color laser printers are made with a stegenography that encodes the unit's serial number in the image.


Now, go back to watching TheVoice(TM) or JerseyCity(TM).
I guess you can use this technology to allow me to spread out all of my money on the floor, take a picture of it, and let my phone count it for me :)

who is that man at the picture
Lol at all the sarcastic comment, but I think this is for easy recognition of international currency during travel.
I gotta buy me a android phone. How's that plan free data cell phone plan going?
I made the detecting counterfeit comment because I have this nearly mystical value about Google at this point... they're going to turn my phone into a tricorder at this rate.

I honestly really love the progress they've made on things like computer vision... stuff that used to be relegated to kids toys is becoming mainstream useful.
now if it told you how much that note is worth in your own currency based on the current exchange rate it might be a lot more useful.
+Edward Dennekamp Well, Google Search already does that, so it wouldn't take much for them to connect those two dots.
I love Google and Android, but does anyone else get the feeling that Google is neglecting their flagship Android 4.0 device, Galaxy Nexus? Every other device (including Nexus S) seems to be getting updates to newer versions of Android faster than their so-called 'flagship'.
i love google so cool
it's also working with Egyptian currency, so fun
Also working on Israeli currency, Nice!
Just a note on +Andrew Bates's comment with regard to Goggles recognising a £20 as a fiver, I can't see how this can happen. Not knowing how the image recognition algorithm works, I can only guess that it works out the image is a British bank note by the Bank of England logo and the Queen's head. Once it's identified that, all it needs to know is the colour: fivers are green, tenners are kind of orange, £20s are purply-blue and £50s are red.

How it identifies US bank notes I have no idea. As they're all green, I find it difficult to tell the difference without looking for the number!

Great work, by the way. Goggles has saved my skin on so many pub quiz picture rounds!
Sorry +Andrew Bates, I didn't mean to imply you were wrong. The point I was trying to make is that the software shouldn't make this mistake due to the very unique nature of British (and many other countries') currency. As I qualified earlier, this is based on little-to-no understanding of how the recognition process works, so I'm willing to be shot down in flames...

Incidentally, I did try this for myself before reading the comments and Goggles correctly identified my fiver as a fiver. Unfortunately, due to being incredibly poor, I can't test a £20!
ahh understood +James Field, sorry I'm having one of those days. Thanks for taking the time and patience to elaborate.

Indeed, it identifies a £5 just fine, but I have tried using Google Goggles on a couple of £20 notes, in different lighting conditions and can repeat the same issue.

+Sylvester Johnson as per my screenshot above, it seems like Google Goggles is using the image of the Queen's face as the identifying factor in determining what note it is seeing, but as you can see it's not really getting it right. Is that screenshot of any use to you for bug fixing? Is there anything else I can do as a user to help (DDMS logs, etc)?
It's a cool feature, and I've tried it with Russian rubles. It recognizes the banknotes fine, even the outdated stuff from the Soviet Union and the 90ies hyperinflation. Still, it describes the old banknotes as just "so-and-so rubles", without mentioning if they are still valid. I think it'd be a very welcome feature, especially for travelers.
Why not make it able to take a picture of multiple bills and then offer to convert it to another currency for us?
Hey, I herd you liek goggles. So, we put goggles in your google so you can google with your goggles while you google.

Did I do it right? D:
Now that's thinking outside the box, +Matthew Sorensen! That is definitely a good way to converge Goggles and Calculator into a real-life usable tool. Nice suggestion!

+Sylvester Johnson, are you reading this? I think most people would love to see more integration between Google services and this is a prime example.
Does it recognize fake bank notes? ;-)
Really one of the fantastic applications in Android. Kudos to its master brain!
Google Goggles never worked for me when I wanted it to.. Its just too hard to rely on - I have tried translating text, landmark images, brand images. The hit rate has been less than 50% so I have given up. Perhaps it will get much better and useful in a couple of years, but for now I feel its useless.
Try to use the Baidu of china !
is there an API for 3rd party developers to integrate Google Goggles into an Android app for specific purposes?
