Their small size allows them to be easily integrated in space-constrained objects, such as stickers, labels, key fobs, and more. NFC is the only wireless technology that can be used to interact with NFC tags. Once it is activated by the NFC reader, the single-interface NFC chip enables the exchange of data between the tag and the reader, when they are brought in close proximity. NFC readers chips are often embedded in smartphones, payment terminals, ticket machines, car door handles, car center consoles, or as part of a broader payment system, such as an automotive or transport application, or a gaming device.įor example, if an NFC reader is embedded in a door handle, the door can be unlocked when the authorized NFC-enabled smartphone is brought in close proximity of the door handle.Ī single-interface NFC chip is a passive device embedded in an NFC tag, which only communicates with the other part of the NFC system, the NFC reader. Supporting multiple RF protocols and features, an NFC reader chip can be used in three different modes: Read/Write, Peer to Peer (P2P), and Card Emulation. Usually, combined with a microcontroller, the NFC reader chip powers up and exchanges information with one or more NFC tags. An NFC reader can also be called an NFC writer, because of its ability to write data into the NFC tag. This article may also apply to mp3 players or other similar devices, which can mount as either a standard USB Mass Storage device or (when using vendor-specific drivers) as a nonstandard device type.An NFC reader chip can be considered as the main controller of the communication system, as it initiates the communication, powers up the NFC tag, and sends commands through the magnetic field to the passive tag. #Readwrite smartphone portableDepending on how the smart phone presents itself to the Operating System it may or may not be possible to use Application Control - typically if the hardware is mounted as a USB Mass Storage device and has a drive letter then Application Control will work, but if the device is mounted as a Portable Device or similar, or if it does not have a drive letter, then Application Control cannot be used.Īpplication Control rules are defined under Policies - Application and Device Control in the Symantec Endpoint Protection Manager (SEPM) console. #Readwrite smartphone windowsTo be able to use this type of detailed filtering with SEP the hardware device needs to be accessed using regular file read/write functionality within Windows certain nonstandard access methods (for example CD-burning) cannot be monitored by the SEP client. With some smart phones select how the device should be mounted (as a USB Mass Storage device, Portable Device, Modem, etc.) - either in a popup menu on the phone when it is connected to the USB port, or as a configuration option within the phone settings - in some of these cases add several different hardware ID strings to the policies, depending on which modes to block or allow.Īpplication Control policies can determine read and write access to files and folders, based on configurable wildcards or the type of device. #Readwrite smartphone installTo find the GUID or device ID string used by the hardware, use the DevViewer.exe tool that comes with the SEP install files in the tools folder. ![]() Device blocking rules are defined under Policies - Application and Device Control in the Symantec Endpoint Protection Manager (SEPM) console, and new hardware devices can be added under Policies - Policy Components - Hardware Devices. Depending on how the smart phone presents itself to the Operating System when plugged in over USB, it may be possible to create Device Control policies to block the device. The Symantec Endpoint Protection client can help keep a computer protected against threats introduced through docked/synched mobile devices. #Readwrite smartphone how toSee Symantec Mobile Security for more details on how to protect Android and Windows Mobile devices. Symantec also recommends defending devices like smart phones with their own mobile security product. ![]()
