GT-10/11 series is equipped with multi communication capabilities, in addition to serial/USB interface, an IrDA port, and Bluetooth are available.
IrDA port is used not only for regular communications with other IrDA peripherals but also for the optional OC-5L Optical communication unit which permits to transfer files to GT-10/11 series over the LAN, also to communicate with the optional IP-1 Security Pendant to increase the security of GT-10/11 series.
Bluetooth enables GT-10/11 series to communicate with virtually any Bluetooth enabled device.
Wireless LAN enables GT-10BCW, GT-10BCLW and GT-11BCW to communicate with your IT network infrastructure easily.
GT-10BCLW has a built in 1D laser scanner, the flexible side keys can be used as trigger keys for the operator to scan barcodes easily by simply pressing any of these keys (depending on the application design), the barcode scanner is capable of reading 10 types of barcodes including EAN, Codabar, ITF, Code39.
For superior expandability, GT-10/11 series is equipped with two types of expansion slots(GT-10B has miniSD card slot only), a CF type II primarily used for communication card like GSM/GPRS or memory storage and a miniSD for memory storage. To physically protect the protruding CF communication card, an optional CF cover slot is available.

To prevent information disclosure from the external storage cards (CF or miniSD) due to accidental loss or theft, when Card security is enabled, GT-10/11 series formats the external media with Canon original format. This format will not be recognized on a PC, also a card formatted on a PC will not be recognized by GT-10/11 series.
IP-1 Security Pendant is a small authentication device that uses the Canon original IrDA protocol to increase the security of GT-10/11 series. When the authentication is set on GT-10/11 series to authenticate via IP-1, only the designated IP-1 device is capable to unlock GT-10/11 series, so in case of a lost or stolen GT-10/11 series device information will be protected. Up to 3 IP-1 devices can be registered to authenticate with GT-10/11 series and the authentication screen can be customised. Management of the authentication history is possible.
The pendant weighs only 15 g and is about 1/3 the size of a bank card. It is waterproof, shockproof, and extremely economical in power consumption, it can run for over one year on one CR battery while being switched on 50 times a day. It is an ultimate solution for the security of GT-10/11 series.
A User Application Mode in which the designated application can run, the operator cannot alter the the system settings which protects the system from potential threats that can cause instability to the system.
A Management Desktop Mode, only the authenticated system admins can install or change the system settings.

On GT-10/11 series passwords and IP-1 Information are stored into a non accessible secured location; information cannot be viewed from any external source. To increase security on CF and miniSD external storage cards, a Root Encryption Key can be set on GT-10/11 series. When this Root Encryption Key is set, passwords, IP-1 information, CF and miniSD card information are encrypted using this Root Encryption Key, so data cannot be read even on another GT-10/11 series device. If these external media are required to be accessed by other GT-10/11 series devices, a special tool can be used on the PC to allow this data access.
GT-10/11 series adopts the most commonly used Windows CE 5.0 as the operating system of the device. This allows an easy development of software applications. The standard Internet explorer is implemented as the web browser; the standard Microsoft windows CE 5.0 mailer can be implemented. In addition special tools are provided in order to make use of the device modules.
The following Microsoft software development tools for Windows(R) CE 5.0 can also be used: eMbedded Visual C++ 4.0 (SP4) (a common development tool), Visual Studio 2005 (a standard development tool), ActiveSync (synchronization software). .NET Compact Framework2.0, required for managed code development, is pre-installed and set up on the GT-10/11. Canon's Custom SDK for development of special applications can also be used to develop applications for GT-10/11 Series devices, such as screens, the built-in printers, communication devices, and modules.
