8.4.3.6.2 Reading distance
Each card needs a specific amount of power. The reader always provides the same
amount of power. Therefore, the reading distance will decrease if more tags are
present. Basically, the reading distance depends on the tag, the antenna and the
tuning of the antenna.
8.4.3.6.3 Multi-tag select
Using the serial number with <CR> as parameter, the corresponding tag will be
selected. High-level interactions can be performed addressing only this card. All
other tags remain silent.

By suppressing the antenna field reset, it is possible to detect only new tags in the
antenna field.

characteristics of the antenna.
