What they are, what they are used for and how to generate QR Code, DataMatrix or EZ Code barcodes - video tutorial

Hi friends, this tutorial will show you how you can generate bar codes with which you convey information, these codes are of several types: QR Code, DataMatrix, Code EZ, etc, of which the best was imposed QR Code These codes can be read with a mobile phone or webcam quality. Even new videotutorial have a barcode in the bottom right, this code may help a user to enter our site without entering any URL in the address bar of the browser on your phone.
On the internet there are many sites that can help you generate barcode behind these points and lines can harbor all sorts of information: phone numbers, text, SMS written on computer, then generate the code, we can read the phone and so we transfer that information into the phone. As is known, it is difficult to enter text using a mobile phone, using these codes can simplify things enormously.
Imagine how difficult it is to type a long email on a phone that has a qwerty keyboard on screen or, to think that Nokia phones with Symbian normal keypad phone with pc can write text quickly that we can enter the phone in seconds using a bar code.
Thereto address You can read a bar code generated by me with the text above, text is limited to 250 characters.
In fact this technology is in its infancy, in the future these codes will become part of our lives, in other more developed countries such codes are used to transmit information in an efficient manner. For example, an ad for a product may contain a certain corner in code like this, code can contain list of stores that can be found in the product and price list, besides it can store a lot of technical specifications related to product presented in this way only those interested can scan the code with a mobile phone to get the details, which otherwise could not be included in that banner.

  • I have a Samsung phone has Java, but it's new model, I found it a program that has as its logo a square one with several smaller squares and I just now realized for what uses. But when you get into it, do not write that picture and I managed to decipher the picture, it's because I am old model monitor those streaks appear?

      Just do not have pictures, have a software that helps you to read those barcodes software that uses the phone's camera to read the codes.

        Well, that's what I said, I found a software, with a square icon, and on the help it says that it can scan ..., and with the help of that program I took the picture, I didn't do it so simply with the phone's camera. :)

  • Cristi, I also found something on the net from android some ok applications for android and that work ok on an htc wildfire a3333 and among those was the bar code that I tested but it doesn't work well on some barcodes, on a kingston card found the barcode, nice. Thank You :)

  • I have a nokia 6300 without operating system, I did kaywa account, I downloaded the software for my phone model, I installed the software in the phone and I set the allowed access.
    go smoothly when taking pictures of these codes, so it looks like you were wrong about that really need a phone with OS

      I tried to be booked, if go is even better, can be used on any phone.
      Thanks for the info.

  • It is a different OCR (Optical Character Recognition). In other words, an ACC (Optical Character Converter)!

    • BGD: Says

      and I'm waiting for that guide. I'm very curious what performance components you will put. I want to change the unit of my old PC (it's very weak 512 mb ram .. empty board of 125 mb ... 1.2ghz processor..it's very weak) so I want to buy a new pc next week or in 2 weeks at a low price (because the crisis affected me too). I saw on emag pc desktops already made (only the unit) at a low price around 10 mil. I wonder if I should take that one or make one at a lower price: S

  • Hi!

    I also have a problem, I want to buy a video card, a network card and a ram memory (how do I know what is the maximum amount of memory accepted?) But I do not know what technical specifications / features I need to consider because these components are compatible with the motherboard so please make a tutorial / article on hardware compatibility.
    PC configuration is:
    Processor: Intel Pentium (Dual-Core) E2200 / 2.2 GHz
    Motherboard: ECS MCP73VT-PM
    Integrated Graphics: NVIDIA GeForce 7050
    Integrated Network Card: Realtek PCI-E RTL8101E Family Fast Ethernet NIC

    You are probably wondering why I want to buy a network card, the answer is simple a few days ago my net crashed (by RomTelecom) I tried to reinstall the drivers for the net but in vain, because it can no longer find the network card. I reinstalled Windows, I checked and in the BIOS everything seems to be fine but the network card still does not appear in Windows (not even as a missing driver as if it no longer exists).

    Thanks in advance!

      To see what memory the motherboard supports, go to the manufacturer's website (type "go ECS" on google) and look at the specifications of the motherboard, there write what microprocessor your motherboard supports, also write what type of memory the motherboard knows (DDR, DDR2, DDR3). Especially to look at the working frequency of the supported RAM (400MHz, 533 Mhz, 667 Mhz, 800 Mhz etc - these details can also be found in the motherboard manual). If your motherboard knows DDR2 at 667 Mhz and you buy memories at 800 Mhz "it can work better" it won't work. Also on the site (or manually) you orient yourself after the video card (video card on AGP or PCIex). If you checked in the BIOS and the network card is enabled (not to be confused with the boot from LAN option, that's something else entirely), I say check right-click on My Computer -> Manage -> Device Manager -> view -> show hidden Devices "to see now if your network card appears. If the network card appears to be hidden, it means that your PC is infected. how to install the drivers from the CD, and not after any partition you put the drivers on, if the partition is infected and you accessed it after installing windows without having any antivirus installed then it will keep you hidden network card. Another reason why your network card does not work is because of the motherboard, it is good to check that you do not have broken capacitors on the card (the network card uses one of the capacitors in the vicinity of the CPU, and if you have broken capacitors on the motherboard, this means that the source no longer filters the current well), look at the LAN socket so that the pins are not destroyed and especially not have play (imperfect contact) with the motherboard.

  • Hi Cristi, when you do the tutorials try to slow down the camera microphone a little bit or move on so that it doesn't sound heard, it doesn't sound very ok, it scratches my ear, the camera tries not to switch from yellow to red in the microphone capture software when you , or if you give it to audio modification you don't give it high or medium you decrease it a bit from gain that is digital amplification let it softer only chassis as it doesn't happen to me so I have a logitech c270 right sound camera that hides the sound from vb I'm cool right? still try to slow down the volume or if it is close to you it will go on and it will sound ok you will see. No offense, I tell you. As the skyscrapers scratch me too much, let me gain more slowly. All the best :)
