First paragraph under Table A-5

"For our example, this value would be 4. The Company Prefix is next (27 bits), followed by Asset Type (encoded in 17 bits)."

This should read:

"For our example, this value would be 5. The Company Prefix is next (24 bits), followed by Asset Type (encoded in 20 bits)."

The previous page refers to the partition value as 5 and the actual encoding shown is partition 5.

Also, checksums are appended to the end of the hex string in messages returned from readers. This is a difference between the early spec in 2005 and the current implementations. So all examples would now have the checksum at the end.

This example should now read:
"3354257BBF40C0E40000849EA4FF7"

instead of:
"4FF73354257BBF40C0E40000849EA"
