The two first names belong to the first Prox–DU device. The two next names belong to the
second Prox–DU device.
Note: The application should use the name of the device for connecting the appropriate
smart card interface.
PC/SC limitations
The Prox–DU and the Prox–SU devices have the following limitations:
• The contactless interface will only support the T=1 protocol.
Consequently any connection requiring the T=0 protocol will not be accepted by the
contactless interface.
• Multi-activation of contactless smart cards is not supported.
Consequently the first smart card detected in front of the reader/writer will be
activated. The remaining smart cards will be ignored.
• The communication with the contactless interface and the contact interface shall be
exclusive.
Consequently the application shall not use the two interfaces simultaneously. Else
communication errors can occur.
