Abstract

The present invention relates to a strap device for a curtain or a flexible door, said straps having embedded RFID reader antenna modules and different MEMS and MOEMS sensors that make it possible to detect the direction of the objects passing through the gate and also detect the size of the objects so as to modulate the switching of the radiating elements of antennas on the basis of the position of the objects being read. The device also has embedded biosensors that measure in parallel the presence of toxic substances or materials. The device according to the invention has an LED or OLED and PHOLED display means embedded in the strap, more specifically, in a flexible material of the strap. The invention is particularly intended for the qualitative and quantitative traceability of materials passing through a logistical check gate. The device is intended for all places already having curtains with flexible straps, into which it is easily embedded. The device is suitable for all existing RFID readers.
