Scaning QR codes - General Questions and Answers

Probably a crazy question but here goes. Is there any way to scan qr code using the same device the qr code is on. I seem to remember there was a browser that could do that. Is there a way or does anyone know of the browser I speak of?

Found some problems with barcode reader though! It would take forever to read the barcode and QR code! Are u reading a barcode or a QR code?

I'm using Barcode Scanner, and i have no issue. It's extremely fast reading both barcodes and QR.

scan qr code directly from device screen

Maybe I'm missing something, but I think it's silly when I come across a qr code when browsing with the tablet that I have to boot my computer, browse to the page, and scan the PC screen with the TF camera.
Is there an app that I am missing that can link from qr code directly?

Try QR Droid.
This is Why I like xda developers site. Every time I search for Something, I always find the answer. Thanks mate.

[APP][2.2+][NFC/QR] InstaWifi - Share and connect to wifi networks instantly

Hi fellow xda-developers,
I am happy to announce my first Android app, InstaWifi. InstaWifi is a new and fun way to connect and share your wifi networks with your friends and family.
I built this with NFC and QR code support. Simply tap on a NFC sticker or scan a QR code to connect to a wifi network instantly. Android Beam is also supported so you can skip the whole NFC sticker part.
Download the app here: https://play.google.com/store/apps/details?id=net.jessechen.instawifi
For more details, screenshots, and tutorials, check out my website: http://www.instawifi.jessechen.net/
Looking forward to any feedback or comments you guys have. Thanks!
Looks great can't wait to try it out

Thanks, let me know how it goes!
Indeed looking great
Am I right someone WITHOUT root can use this to connect with current WiFi?
I suppose so..
Thanks

Two questions...
1) Does the other person need to have the app as well, or will just any QR scanner app on any Android device work with this?
2) You can probably guess where that question will lead next, if someone has an (ugh!) iPhone or iPad with a QR scanner app, will it be able to automatically connect as well?
Thanks!
Loving the concept of the app, and it Works!

Yes, root is ONLY used to pre-populate the security type and passwords so that you don't have to manually type it in yourself. It is not required at all in order for it to work otherwise.

1) The other person needs to have the Barcode Scanner app installed (https://play.google.com/store/apps/details?id=com.google.zxing.client.android). It's the most popular barcode scanner app out there with ~50,000,000 downloads, so most people should have it already.
2) iOS devices can't automatically connect unfortunately due to the limitations of apple's platform (apps cannot control/manipulate wifi). If that ever changes you know I'll be there to write an app that can do it!
Tested this with my Galaxy S2 (GT-I9100).
But I can't connect to my Wifi via QR-Code. Is there a (known) issue with hidden SSIDs maybe?
The Wifi Settings of the phone tell me the Wifi is "not in range".
I'm on CM10 with Siyah Kernel.
An excellent app.
An extremely minor suggestion: not use a square icon but one with a "distinctive silhouette".
Can totally be ignored though

I believe hidden SSIDs have an issue with this. I'll try to see if that can be fixed in the future.

Hi, I have a Galaxy Nexus with CM10 and InstaWifi is no longer populating the password field.
Code:
D/su (20451): 10080 net.jessechen.instawifi executing 0 /system/bin/sh using shell /system/bin/sh : sh
I/k (20159): sudo made me a sandwich
I/k (20159): no root access, returning null password value

As I don't have NFC can the QR code be saved so it can be opened in gallery later, rather than having to launch InstaWiFi again?
You might also want to add cancel to the popup that asks to connect to WiFi. I opened in error and had to turn on WiFi before I could exit out of InstaWiFi.
Just my .02 cents.
Nice Idea, but Useless...
Its a nice idea though. But its a useless and impractical idea.
I think verbally spelling out the wifi password to the guests/friends is easier, time saving and hassle free because everyone has at least mouth & ears to communicate password.
Everyone doesn't have that app,
Everyone doesn't have Android,
Everyone doesn't have QR code reader/Barcode reader,
Everyone doesn't have NFC or beam
and to avoid all the hussles and frustration of not getting it through.... just communicate the password verbally... It just takes a moment to say a password rather than bieng in this hassle

let me correct your grammar (or typo?):

Let me answer some of your questions:
- "Not everyone have Android." are u kidding me dude? You are here, the Android community! other OS are not talked here, they talked in other section!
- "Not everyone have QR code reader/Barcode reader," Yeah, you can always download it from Play Store
- "spelling out the wifi password to the guests/friends is easier." How do u can spell if the password is XdAiSTHEbest!ILOVExda#[email protected]$
Nobody answered pretty straight forward question. Does the receiver needs to have the InstaWifi app?
If yes, petty because it is easier to pass the password old fashion way.
If not, great app, especially for bars or public places...

Short answer: no.
According to the xda video on InstaWifi the recipient/receiver just needs to scan the QR-Code or a NFC capable smartphone.
Edit:
Apparently it is not as a simple/short answer as a 'no'. Sorry, my bad. The OP explained it in the post below.
Thx for the clarification.

Yeah, I understand that this can be a bit confusing. I'll try to break it down as simple as I can:
NFC:
1) Receiver must have the app installed, Android does not have native support to connect to a wifi network instantly, an app (which in this case, InstaWifi) needs to handle the incoming NFC data and connect to wifi for you.
2) If the receiver does not have the app installed, tapping the NFC sticker automatically takes you to the play store to download InstaWifi. Once it's downloaded, tap the sticker again and you should be good to go (hopefully less than 20 seconds for the whole ordeal, which can still be faster than typing out a super long password).
QR:
1) Receiver does not have to have InstaWifi installed. Reciever needs to have the Barcode Scanner app installed for it to work.
Hope that clarifies some things.
kool concept Loving app
But what if someone wants to use wifi and already at your house and has neither Data plan or QR reader or this app lol

Thanks for the grammar correction bro...
Now let me get back to your replies:
"are u kidding me dude? You are here, the Android community! other OS are not talked here, they talked in other section!":
Agreed.... But I meant to say that everyone visiting my place and asking for wifi password do not need to belong to Android community. do u understand that now?
"Not everyone have QR code reader/Barcode reader," Yeah, you can always download it from Play Store:
Let me put it this way....
Friend: whats your wifi password?
Me: you can scan the QR code for that dear.
Friend: but i dont have the QR Code reader
Me: Oh! AngSanley said you can always download it from Play store :angel:
Friend: But how can i download it from the Play store unless you don't tell me the password to connect to internet through wifi?
Me: Thats not my business :laugh: \
"spelling out the wifi password to the guests/friends is easier." How do u can spell if the password is XdAiSTHEbest!ILOVExda#[email protected]$:
Friend: Ok F**k it, just spell out your wifi password.
Me: XdAiSTHEbest!ILOVExda#[email protected]$
Friend: Whaatttttt?????????? who keeps such complicated passwords?
Me: The ones who are fond of using Instawifi app anyway
Friend: Get a life dude! You are complicated...

This application works the best for me, reads even the biggest codes in less than one second:
https://play.google.com/store/apps/...rcode.barcode.scanner.reader.flashlight&hl=en
The code that you're trying to scan is most probably invalid if it doesn't detect with any apps that you try.

Not a single ad, popup or message for me, just automatic fast scanning. Weird
I use this one: https://play.google.com/store/apps/details?id=me.scan.android.client
Have never had any issues with it. Just scan the code and click download.
Use bixby vision, hold the phone close to the code and not far away.
A QR option will appear.
Bixby works flawless for me, I don't understadn what the problem is...
Sorry on the reply delay. Bixby is working. I have to click the item sometimes or resize and QR code will pop up. I will try one of the app ad prevents.
I cant speak on a 3rd party QR reader. The highly rated ones i mentioned above didnt work though.

Seems like my WhatsApp hacked without scanning QR code

I've sent an image to my friend on whatsapp and I've sent exactly same image to another friend but my 1st friend knows to whom i sent that image with contact name without touching my device (Without scanning any QR code and without any spy app)
He don't want to tell me that how could he do that.
Can anyone help me to understand this..??
