4.5 Same card results in different ID codes
If the presented card support multiple protocols, then it vary which protocol
will be returned. For example if the card support both HID iClass and HID Prox,
sometimes the HID iClass ID code is returned and somethimes the HID Prox ID
code is returned. Solution:

Configure the card reader to allow selective card reading, by disabling
the unused and/or undesired protocols (3.5).
A similar situation will also occur if multiple cards (same or different protocols)
are presented at the same time. This can for example be the case if the user
are storing multiple proximity cards in a wallet and is placing the wallet on top
of the card reader.

Ask users to only present one card at a time. In SafeCom Administrator
on the Users tab in the Server properties dialog you can specify the Max
IDs per user .
4.6 The ID code appear different in SafeCom
Administrator and Notepad
If a filtercard.dll has been installed as part of the SafeCom solution the ID
codes are different. The filtercard.dll does on-the-fly ID code conversion. This
conversion does not occur when the ID code is written into Notepad.
4.7 Reader behaves differently after RMA process
A Nuance Mx Proximity Reader is always shipped with the default configuration,
regardless of if it is shipped in response to a new order or as a replacement unit
as part of the Return Material Authorization (RMA) process.
If a configuration was applied to the existing Nuance Mx Proximity Readers then
the same configuration (3.5) should be applied to the received Nuance Mx
Proximity Reader before it is deployed.
