Aah, I reverse-engineered them from the output of "nfc-list" (included in
LibNFC), but http://wg8.de/wg8n1496_17n3613_Ballot_FCD14443-3.pdf has a small
amount of info (although the PN532 doesn't expose everything according to that
spec).
For a Maxim MAX66040E-000AA+, things look like:
1 ISO14443B passive target(s) found:
PUPI: a2 a6 02 00

For a two different capacities of Atmel CryptoRF:

* PICC supports only 106 kbits/s in both directions
* Maximum frame sizes: 24 bytes
* Frame Waiting Time: 9.666 ms
* Frame options supported: NAD

Unfortunately, I don't have any more types of ISO 14443-B tag/card; and the USB
cable on my reader is dodgy - but there are examples from these in some of the
trace files that I've uploaded.
