We have had some real good results with UniFLOW.
We have used the Canon Prox card readers, as well as a number of different RFIDeas card readers.
If you use the Canon \ NTware card reader you don't have to configure the meap app to talk to it, if you use the RFIDeas card reader you will need a CFG file and the proper web page to configure it.
Your Canon Support guy (SE) will be able to help you figure out the right card reader. If you need an RFIDeas contact email me.
