This weeks Sunday activity: playing around with an Omron V3TU-1K magnetic card reader with USB interface.
Second (or third, fourh .. ) hand, and of course no drivers to be found anywhere.

UPDATE:
After contacting Omron Europe, I finally got drivers for it from Cetwin Service which seems to still have support for these. To spare them the extra work I’ve put the driver zip file up on the web here. Since the reader is very old and probably not in sale anywhere any more, this shouldn’t hurt anyones feelings.
In the end my reader was unable to read a single card. It is detected in Windows and seems to work, but any card I try to read it just beeps and flashes unreadable.

I am also looking for this driver.
In the meantime I have found an USB magnetic reader, plug and play, without installation by a little company in Belgium : Corona Print in Brussels.
No driver needed ! There is also a little configurator with which you can chose the tracks you want to read and other useful parameters.
If you found more information about this Omron reader, I am interested to get the right driver.
Best regards,

I have got the same trooubles with my reader. Finely I have get all the answers on my questions by contacting Corona Print who is distributor of Omron in Brussels for BeNeLux. It works also on Windows 7 32bit. It was a keyboard problem. They found the solution quickly and friendly !
