Hi, Please don't hijack threads - this is a different discussion so a different thread :)
I can give you a quick answer. We scan a *lot* of tags, and also noticed a small set of NfcB/ISO-DEP cards that are a little tricky. You have to orient the antennas in just the right alignment, and it can take a couple of seconds. I asked our vendor and they explained that some NfcB cards are designed to work with limited RF sensitivity, since they are designed to work with fixed reader/writer infrastructure that has larger antennas and higher power. There is no way to adjust the power. I think you will find any NFC Forum tags will work fine however.
