silly question about hash image

hi

well , i have really a silly question about this image

i don't know even how it's called in english or my motherlanguage

is used to like the hash for the files ?


is there a tool to create it?

thanks

 

Hi mantra,

It is called QR Code.
The QR code contains the file URL. I guess it's not hash for files but URL address coded.
Because if you move your mouse pointer over the image in this example - then you will see the title text says "File download URL". Also check out the URL address of this image as a confirmation.
These codes are useful in situations where you may need to download the file or access the webpage to/from a mobile device.

 

thanks a lot Creer

 

thanks for the programs JRViejo

 

hi
only a question , i found these QR code in paper magazine too or in advertising papers

 

That's because generally everyone have handhelds (smartphones, tablets, etc.) that can easily scan these codes using apps these days.

 

You are welcome.

That makes sense, by using these codes you don't have to enter sign by sign URL address in your mobile device.

 

It doesn't have to contain URL addresses. It can contain names, phone numbers, email and other addresses. Thus, scanning in your phone it can become a contact.

Best regards,

 

Hi Mantra,

These QR codes are on people's businesses and visiting cards. By scanning in it then becomes a contact in the phone book.

Best regards,

 

thanks Aladdin!

 

You are welcome Mantra,

The image doesn't have to be in black only. It can be very colorful, consisting of more than one color. Also, it can contain the logo of the company or the name of the company in the middle. The information is contained in the three square boxes, the two at the top ends, and the one on the bottom left end. Only three squares.

Check out the QR codes for KFC (Kentucky Fried Chicken)

Best regards,

 

P.S. There is a fourth square at the bottom right, but it is not at the edge like the other three squares, and not as big too.

Best regards,

 

thanks again really very kind

best regards to you!
