the reader is now configured and it works. when it detects a tag, the windows software tells you
Tag ID,Tag Name,Tag Type, Total Reads, Rate, Antenna, Date/Time

this is what the serial data looks like, 57600 baud: (it repeats constantly while the tag is nearby)
we got these 900mhz band RFID tags available from mouser.com as part number SL3S1202AC0,118 they cost 8 cents each. http://www.mouser.com/ProductDetail/NXP-Semiconductors/SL3S1202AC0118/?qs=sGAEpiMZZMvQHWqrh58LgXtw8BZ1psdi%252bSfsWYs2XZg%3d
the picture on the mouser site is wrong for these parts, they do not look anything like a 1206 capacitor.

- Antennas: From the NXP app notes:
- AN1523 has a reference design for a mid-range less than one meter read distance antenna. The antenna is 34 mm x 15 mm.
- AN0972 has a reference design for a "general purpose" antenna with an optimal read range of 2.5 meters. The antenna is 1.25" x 0.875"
- AN0969 has a 98 mm long antenna design, with a read range of 1 m to 6 m depending on the substrate you use. Teflon and polystyrene are best; Rogers TMM6 is the worst but has the least variation across the frequency range.
- AN1615 has a short range ring antenna design. 8.3mm diameter ring. Read range of 2 cm.
- AN1685 has an 80mm x 35mm antenna design, with a 6 meter read range.
