RFID tags point the way to the blind
RFID tags placed on the sidewalks of Italy help blind people to move around in unfamiliar places. This project is carried out as part of a research project funded by the European Union called the SESAMONET (Secure and Safe Mobility Network), which aims to improve the lives of visually impaired people.
In the city of Laveno Mombello, the project developers created a path of about 2 km long RFID tags that leads from the city’s railway station to Lago Maggiore Bank, loop in a park near the lake, and also pass through several intersections. About 10 people, with poor or absent eyesight, test the system using specially designed canes, which act as readers for 125 kHz passive Tags, in ceramic cases that are buried in tracks. Thanks to these tests, developers get the necessary information to improve the system.
When a blind person approaches the tag, his cane recognizes it (the reader’s antenna is built into the cane’s tip, the power source and the Bluetooth transmitter are integrated near the handle). Unique ID Tag is sent, via a Bluetooth transmitter, to the user's PDA, in which a special program is running that determines a person’s location. The program quickly sets the direction (with the help of voice commands of the program), or various sound signals, which are then transmitted to wireless headphones dressed as a tester.

The scope of application of RFID-systems is constantly expanding, besides the already existing methods of using RFID, which will be improved, there are many areas that are ready to adopt technology. The potential of using RFID is enormous.
Composition of RFID system
Tags (tags, transponders)
passive (read only information)
active (single write and multiple read or multiple read / write)
Readers (readers, antennas)
stationary
mobile
with different ranges
in room and outdoor performance.
System
writing data to tags
placing tags on goods
read data from tags
adding data to tags (about controls, etc.)
data collection and processing
transfer to other sites for control
reports and analytics.
The advantages of RFID systems compared to other identification methods
supported by major software providers (Microsoft, Oracle, SAP, etc.)
no contact or direct visibility needed
fast and accurate reading (close to 100% identification
good protection against environmental influences
passive tags have virtually unlimited lifespan
tags carry a lot of information
RFID tags are very difficult to fake.
RFID tags can be not only readable, but also with the ability to record information
the data on the RFID tag can be classified
the ability to simultaneously read multiple RFID tags at high speed.
Key RFID Applications
libraries and archives - search for literature, registration of received books and returned books to the library fund, inventory
trade and logistics - accounting and control of the movement of goods, goods, passing checkpoints by transport, inventory, etc.
public transport - traffic management, fare payment and passenger traffic optimization
security - control of access and movement of personnel in the territory and others.
RFID Tag and reader
A label is a small device for storing and transmitting information. It consists of a microchip and an antenna with which it transmits and receives information. There are tags that have a built-in power source (active tags), but the bulk of the tags used today do not have a built-in power source (passive).
A unique number and / or a certain amount of user memory is stored in the memory of the tag. When a tag enters the reading zone, this information is received by the reader (reader) - a device capable of reading and writing information in the tags, and transmitted to the computer for further processing.
