The bird had the right idea!

I installed the software for the IRIScan Express and was not surprised to see that it isn’t TWAIN compliant. However, the ReadIRIS software that comes with it DOES use TWAIN compliant scanners if they exist. In poking around, I see that the software opens up a bundle specifically for the scanner. (I used a tool called opensnoop to see what the app was opening.)

 501   1867 Readiris       6 /Library/Application Support/IRISScan/IRISScan 1.6.bundle 
  501   1867 Readiris       6 /Library/Application Support/IRISScan/IRISScan 1.6.bundle/Contents 
  501   1867 Readiris       6 /dev/autofs_nowait   
  501   1867 Readiris       7 /Library/Application Support/IRISScan/IRISScan 1.6.bundle/Contents/Info.plist 

TWAIN drivers live in /Library/Image Capture/TWAIN Data Sources. It doesn’t look like the IRIScan folks did the right thing and create a TWAIN driver. Instead they created their own system for talking to the scanner. The scanner is a Plustek scanner (according to USB Prober). I haven’t found Plustek drivers, yet, but will keep searching.

So, the IRIScan scanners won’t work with ReceiptWallet. Piece of crap scanner. I’ve sent email to them asked where the TWAIN drivers are as the sales guy told me it was TWAIN compliant and how can I return the scanner. I’m sure I’ll get a great response to my message.

I should have heeded the advice of the bird and returned the scanner while I still had the chance and before I left the show. Anyone have a need for a paperweight? Their software is so awful that I wouldn’t even think of using it.
