Read problems (Tag-it HF-I Plus Inlay)
Hopefully this will help in improving the module - the Read Block command can be a little flaky, trying to read a block from a Tag-it HF-I Plus Inlay (Texas Instruments). Note that the block data is 09 5F 9D B2, below are outputs from attempts to read the block without and with debug mode on respectively:

Re: Read problems (Tag-it HF-I Plus Inlay)
try the "hf 15 cmd sysinfo"? are you sure its a iso15693 tag?
and finally, how is your antenna output (hw tune) ?

Re: Read problems (Tag-it HF-I Plus Inlay)
Antenna is working normally (I always run a tune before doing any tests as it can be a bit flaky):
[== Undefined ==]
Measuring antenna characteristics, please wait...#db# DownloadFPGA(len: 42096)
....#db# DownloadFPGA(len: 42096)
# LF antenna: 0.00 V @ 125.00 kHz
# LF antenna: 0.00 V @ 134.00 kHz
# LF optimal: 0.41 V @ 169.01 kHz
# HF antenna: 13.90 V @ 13.56 MHz
# Your LF antenna is unusable. The card reads fine on a Galaxy S6 using the NFC TagInfo app. Writing to the tag using the Proxmark worked when setting the OPTIONS flag, however the feedback was still that the card didn't respond but data may have been written anyway (writing was actually fairly reliable).

Re: Read problems (Tag-it HF-I Plus Inlay)
I don't know the status on the "hf 15" commands, there were issues (ref: https://github.com/Proxmark/proxmark3/issues/20) on github ealier.
