Our new device is called ReTAG device, which consists of a 3.5 inch LCD touch screen, UHF and NFC antenna.
A 3.5-inch TFT (Thin-Film Transistor) LCD Touch Screen Display is a compact and portable display which features a 3.5-inch color TFT LCD panel that offers vibrant and high-quality visuals. UHF antennas are designed to operate in the UHF frequency range, which typically spans from 300 MHz to 3 GHz.
UHF signals have relatively longer wavelengths, allowing them to propagate over longer distances compared to higher frequency signals.
NFC antennas are specifically designed for Near Field Communication technology, which enables short-range wireless communication between devices. When two NFC-enabled devices come into close proximity, their antennas create a magnetic field that enables the exchange of data.
Depending on whether the tag was scanned by UHF or NFC, the screen on the ReTAG device will display the data it receives from the server. Device receives data about ID and goods on that tag. After scanning the tag, the user can move goods on the other tag, or destroy the previous tag from the database.
