About Near Field Communication (NFC)
NFC technology provides the ability for short-range, wireless data transfer
between the CT40/CT40 XP and NFC tags or other NFC enabled devices placed in
close proximity to the back of the computer. All CT40/CT40 XP mobile computers
support the following modes of operation:
• NFC tag reader/writer mode: The computer reads and/or writes digital
information from or to an NFC tag.
• Peer-to-Peer (P2P) mode: The computer uses Android Beam and/or Bluetooth
technology to transfer screen content (e.g., a picture, contact information, Web
page URL, or file) between NFC enabled devices.
• NFC card emulation mode: The computer emulates an NFC card (smart card)
that an external card reader can access. You can download and install apps for
card emulation mode from the Google Play™ store. Some examples include
digital wallets (e-wallets) offered by your bank or credit card company and
Google Pay™. The app you install determines the type of emulation mode used:
Card Emulation with a Secure Element or Host-based Card Emulation.
Secure element use is common for financial transactions that require a high
level of security in order to provide a secure memory and execution environment
for running custom smart card applets and storing your personal information
(e.g., account information and credentials).
Note: When using a Universal Integrated Circuit (UICC) card for NFC Secure Element NFC
link encryption, install the card in SIM slot 1.
