Configuring the Broadcom Contactless Smartcard Reader for Proximity Card Users

You can use MIFARE or iClass proximity cards with the Broadcom Contactless Smartcard reader embedded in some Dell laptops (Latitude E-series and some Precision laptops).

Enabling the Broadcom Contactless Smartcard Reader

On each affected laptop, run ushradiomode64.exe-n from the command line at C:\Program Files\Broadcom Corporation Broadcom USH Host Component\CV\bin\

Using iClass Proximity Cards with the Broadcom Contactless Smart Card Reader

To use iClass cards, you must follow a few more steps:

• For 32—bit systems, from the command line, run regedit.exe. Go to HKLM\Software\SSOProvider\DeviceManager\Devices\Prox\Providers\Broadcom\ and rename FactoryLoadID to ~FactoryLoadID
• For 64—bit Windows 7 systems, from the command line, run regedit.exe. Go to HKLM\Software\SSOProvider\DeviceManager\Devices\Prox\Providers\Broadcom\ and rename FactoryLoadID to ~FactoryLoadID
3. (Windows 7 only) Disable the built-in Windows smart card provider:
4. From the command line, run regedit.exe. Go to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\Credential Providers and disable the following registry keys by adding a ~ to the beginning of the key name:
