System Overview
6.1 System description
The Hi-G-T ek system consists of the following components:
1. DataSeal
The DataSeal is a sophisticated device, which includes 2
transmitter/receiver units (one for high frequency/long range and another
one for low frequency/short range communications), real-time clock,
processor, memory and sensing circuitry for sealing verification. The
Sealing Wire prevents any attempt of opening, bypassing, or tampering
with the DataSeal without alerting the system and recording the event.
Data may also be written into and read from the DataSeal to store and
retrieve general information. The DataSeal can communicate both in low
frequency with short range devices, such as the DataTerminal and
MicroDataReader, and in high frequency for long ranges with the
DataReader, together allowing a broad range of applications.
2. DataTag
The DataTag is a variant of the DataSeal device. Instead of the Sealing
Wire it has a removal sensing mechanism. T his makes it more suitable for
cases where you want to tag goods, but you don't have to seal them. Other
than that, it is identical to the DataSeal device.
3. MagneticDataSeal
The MagneticDataSeal is a variant of the DataSeal device. Instead of the
Sealing Wire it has a Magnet element. This makes it more suitable for cases
