Hardware dongle with built-in battery and clock

Real Time Clock dongle with built in smart-card based time clock and rechargeable battery for time limitation solution.

Easy to use, driverless hardware dongle with inbuilt smart-card based time clock and battery.

AuthGuru RTC dongles contain highly accurate internal clock which helps in defining tamper proof time expiration. Very popular and commonly used in for high performance requirement in Raspberry Pi, Games, Software application of various languages and platform.

Real time dongles with inbuilt battery and clock

Why choose RTC Key

AuthGuru RTC keys has an on-board clock chip which can charge through standard USB port, and this clock chip is independent from PC so the time-tamper issue will not affect RTC key. Additionally, we add the multiple nodes control strategy to help user set the usage time, expiration time.

High Performance Hardware

These are high performance dongle with built-in 32 bit smart card security chip. It is based on USB full speed mode and supports USB 1.0 and above.

Multiple OS support

RTC Dongle supports all OS in the market, and has been tested comprehensively, including Windows series both 32 bit and 64 bit, Linux and Mac OS.

Multiple programming languages support

RTC Dongle comes with various APIs for all commonly used development languages, such as C/C++, VB, .NET, Visual FoxPro, Delphi.

Usage count limitation

Developer can choose to open or close this function. After usage, the counter will auto minus 1 until the counter shows zero. In this case, the dongle has to be activated by remote authorization, or user can no longer use it.

On-board independent clock chips

It has an independent high-precision clock chip, which includes rechargeable battery and intelligent battery management unit. With all these functions help, the PC interaction and lasting time issue can be solved efficiently.

Higher capacity, Performance & Storage

RTC Dongle has built-in maximum 16K storage space. No limit read, write times up to 100,000. While the memory storage has no limit to read and write, Developer can flexibly and efficiently use these storage to reach best effect.
