[Noisebridge-discuss] seeking donation of RFID reader equipment

[Gopiballava Flaherty]

Ack. Sorry I missed that. 

The mouser URL implied that you needed an external antenna. 

Unfortunately, I'm fairly confident from the data sheet that the FCS2 package does not include an antenna:

a) Page 7 gives a pinout which says that it has two connections, one for each antenna pin
b) Different antennas have different characteristics. I don't see any discussion of how the performance of the FCS2 package antenna is, or when you might use it vs. a different antenna

c) I don't see any text that says "Also comes in a package with a built in antenna to make your life easier!!!" I usually see something like that. 

I know this is all a bit circumstantial but my experience with data sheets is that the component is always worse than you expected :)

Thanks,
