The Topaz Model LinkGem T-RFS261-P1B is a rugged and complete wireless signature capture system for anywhere that the benefits of eSignatures are needed. Topaz LinkGem wireless tablets allow businesses to replace paper-based document transaction or identity verification with secure and legally-binding electronic signature applications. The frequency-hopping spread-spectrum 2.4GHz wireless transceiver used by Topaz LinkGem tablets allows for extreme portability in a wide variety of eSignature application environments. For example, the wireless design can be used for ID verification through a bulletproof partition in a law-enforcement or correctional facility where running a data cable is not a viable option. The unit is also useful at drive-up teller windows in banks or pharmacies where it can be passed easily from the teller to the customer and back again. The design of the active Topaz PenGem pen allows the sensor to be mounted inside the rugged tablet housing, meaning that the signing surface will never wear out, even after millions of signatures. The Topaz PenGem itself is rated at over 30 million tip activations, but should the need arise, batteries and plastic pen tips can be easily replaced without any disassembly required. The convenient design of the tablet features pen storage, proximity alert, remote activation, and power-saving standby mode. The base unit can be hot-plugged into the computer and need not be connected during the boot process. Tablet MTBF is 1 million hours and the pen batteries offer a lifetime of 250,000 signatures. Topaz SigPlus ActiveX Java, shared C library and applications software allow for signature capture, encryption, and image-file creation. Receiver base adapters are available with standard RS232 (serial) or USB interfaces.
