Functional Description

5.4 Functionality

5.4.1 General Information

The LFP Handheld Reader USB is a radio frequency identification system that uses radio transmission
to read or write data from LF transponders (134.2 kHz).
The core piece is an LF transponder (134.2 kHz) which operates as a forgery-proof electronic tag.

The reading unit of the system transmits an energy pulse via the antenna. The transponder is supplied
with energy by this pulse. The transponder then sends the stored data back to the device.

The reading process takes approx. 100ms (communication between transponder and device).
Since a line of sight between the device and transponder is not absolutely necessary, the transponder

can also be identified through non-metallic material.
The LF Handheld Reader USB reads all 134.2kHz transponders according to ISO18000-2 (and

ISO11785) common on the market.

5.4.2 Normal Operation

During normal operation, the LFP handheld reader is immediately ready for operation after a reset.
It does not perform any independent actions in this mode.
Pressing the read button triggers an automatic reading and, if the reading is successful, the data of the LF

tag are output.

5.4.3 Polling Mode

The reader can be set to a state of continuous reading, the so-called polling mode. The device then
performs a readout at regular intervals and outputs the data of the read LF transponder.
