RFID - Radio Frequency Identification

RFID (Radio Frequency Identification) is a major and fast-evolving technology appearing to have a tremendous future. This is an identification technology which employs special readers able to read at distance an IC containing data related to persons, objects, locations, etc... The RFID technology uses very low power radio frequencies which can travel through non-metallic materials allowing data readings and writings without contact.

Depending of applications, LISCOM uses radio frequencies between 50 kHz to 2.5 GHz.
Low frequency (50 kHz to 14 MHz) systems work generally at short distances and do not require approvals by telecommunications authorities; furthermore, they are not too sensitive to metal and electrical noise.

Higher frequency systems (14 MHz to 2.5 GHz) work over greater distances ;  they may require approvals. Like other automatic identification technologies, RFID speeds the data capture and does not require for human operations in the process. RFID is ideal for harsh commercial and industrial environments.

RFID readers have no moving parts ; the systems need almost no maintenance and can operate without failure during long periods of time. The transponders have extremely long life and will last longer than the object to which they are attached.

Unlike bar codes and magnetic coding, RFID transponders are practically impossible to copy. This is an ideal technology for confidential identification either of people or assets. LISCOM RFID is fast as the transponder and reader can communicate in milliseconds ; data transfer rate is typically of 30 to 100 milliseconds.

Because RFID will read through non-metallic materials, the internal components are usually packaged in materials that can survive very harsh environments between -40°C and +80°C. The good quality transponders are not affected by most caustics and will be read through dirt, paint, cement, oil, wood, etc....
