I have been dabbling in writing a custom application that uses .NET. I am currently working with ThingMagic (Jadak) but have had issues getting a consistent read. Lot's of communication with tech support but no resolution yet. From what I can tell there is also Zebra and Impinj - there may be others.
Jadak has been problems getting a consistent connection to their reader. One time it will work and then next the reader will reject the connection attempt. They are working on this but no word yet.
Although Zebra is a pretty ubiquitous name in printers they worry me because there are a limited number of supported readers and the API version looks a little outdated.
Impinj looks pretty straightforward - just no experience at all with them.
Anybody have experience with .NET (C#) and RFID readers?
Who has a solid but not complicated API?
Who has a solid physical product offering?
