.NET compatible qr scanning devices

Is there a scanning device that makes it easy to communicate with the .NET platform?

The scanning device must be:

  • Portable (therefore, it should be able to store data inside itself until it is connected to a PC)
  • It should be able to scan QR codes and display the corresponding parameters on the device’s built-in screen.
  • Must have a programmable display that provides user options after scanning in a QR code.
  • After connecting to a computer, it should automatically make any changes to the network database based on temporary data stored on the device, which will depend on which qr codes were scanned and what parameters were selected by the user after scanning the qr code.

I used the .NET tag because it is the language used by the environment in which I will work.

Expensive, but the Cognex 9500 should do everything you need:

This is mainly a Windows PDA attached to a barcode reader. You can write your own applications in the .NET Compact Framework to work on the PDA, and then the C # API, if you want to use the scanner from a PC.

  • Get iPod touch. Even the smallest iPod touch can store more than enough data when scanning QR codes.

  • Write a small application using the zBar SDK (free, LGPL) http://zbar.sourceforge.net/

  • Equip your data from iPod to PC - for example, using http

I created a prototype for scanning QR codes, saving them locally and then dragging data via WIFI to the Access database for a day. My application also retrieves configuration data from the Access database, controlling certain options in the user interface.

You are a couple of $ 100 (for iPod) and a day away from the prototype.
