Using a Bluetooth Headset
You can use a Bluetooth headset for audio communication when an audio enabled application is used. See
Bluetooth on page 132 for information on connecting a Bluetooth device to the mobile computer. Ensure that the
mobile computer’s volume is set appropriately before putting the headset on. When a Bluetooth headset is
connected the speaker is muted.
Near Field Communications
NFC/HF RFID is a short-range wireless connectivity technology standard that enables secure transaction between
a reader and a contactless smartcard. The technology is based on ISO/IEC 14443 type A and B (proximity), Felica
and ISO/IEC 15693 (vicinity) standards, using the HF 13.56 MHz unlicensed band. The MC33XX supports 3
operating modes:
• Reader mode
• Peer-to-Peer communication
• Card Emulation mode.
Using NFC, the MC33XX can:
• Read contactless cards such as contactless tickets, NFC labels, HF tokens or standard smart cards.
• Read and write information to contactless cards such as SmartPosters and tickets, as well as devices with
NFC interface such as vending machines.
• Read information from supported medical sensors.
• Pair with supported Bluetooth devices such as printers, ring scanners (ex. RS6000), and headsets (ex.
HS3100).
• Exchange data with another NFC device.
• Emulate contactless card such as ticket or V-card.
The MC33XX NFC antenna is centrally aligned with the back housing directly underneath the regulatory label and
is designed for reading a range of NFC tags at distances from contact up to 2 cm from the rear of the device.
NOTE: If the mobile computer goes into suspend mode the Bluetooth connection is disabled and the
mobile computer automatically switches to speakerphone mode.
NOTE: NFC is supported on the premium and premium + configurations of the device.
