Function: It allows for the status of the card reader to be questioned to confirm whether
there is a card in the field that it is being filtered in multiread mode. If there is no card in
the reader field, it will return just one argument byte.
The reader code may be made up of decimal ASCII characters (from ‘0’ to ‘9’) or
ASCII-Hex (from ‘0’ to ‘9’ and from ‘A’ to ‘F’) characters. It may also include an
indicative prefix of the reader to have read the card (see Subsection 8.1.4.).
9.6.18. Card Reading
Function: It returns the code read by the card reader. It may be made up of decimal
ASCII characters (from ‘0’ to ‘9’) or ASCII-Hex (from ‘0’ to ‘9’ and from ‘A’ to ‘F’)
characters. It may also include an indicative prefix of the reader to have read the card
(see Subsection 8.1.4.).
If the reading was erroneous, the frame is returned with 0 arguments. This will enable the
Host to act on the LEDs or the Beeper to inform users of the success of failure of the
operation.
If the multiread filter is enabled, a code based on special characters (e.g.
‘***********’ for TTL_0) can be obtained to indicate that the card has been
removed from the reader.
9.6.19. Key Pressing
Function: Returns key code pressed for Online management according to the following
table:
