Note
The insertion and removal of the card must be done in a
continuous motion. If not, the Reader may not read the encoded
data properly. In that case, the Reader responds to an inquiry
command by either transmitting the ASCII character “E””
representing an error, or by just transmitting status characters,
which indicates that the Reader has not detected any data and the
card was not completely inserted.
