@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.
