@Christopher-Bunnell I did a little research and the card you select will impact the robustness of readability and amount of data you can write to the card. I did find a demonstration of several tags and the NTAG213 was picked up from a distance of 3.5 CM from a reader which was the best performing tag in this test. The Mifare Ultralite was the poorest performing in terms of needing to be .5 CM from the reader to be read.

I need information about the 13.56 Mhz Mifare cards used with the RFID\NFC expansion. I want to know if some cards are "better" than others in terms of the reader more easily being able to read the card. If so, what specifications do I need to look for to choose the card that will be most easily read?

I am having trouble following the instructions for the Hologram Cellular Expansion Guide. [https://onion.io/2bt-using-hologram-expansion/](link url)

Where the instructions say "Now it’s time to connect things together:"
Plug the Omega2 into the Dock (Which dock are we talking about? The expansion, Arduino or Power Dock?)

Plug the Hologram Expansion into the Dock’s Expansion Header (Which dock are we talking about? The expansion, Arduino or Power Dock?)

Plug the SIM card into the Cellular Expansion’s SIM card slot, located on the bottom (The Onion cellular expansion example looks like the picture below and mine looks like the example just below that (link provided). I do not see a place on my Hologram for a SIM card. My Hologram DASH has 36 pins and I see no place where they would plug in. Please explain how I get the correct equipment and everything put together correctly.):
