RFID tags, also known as “Smart labels”, are identifiers with memory support, which have the form of real adhesive labels, able to exchange radio frequency information with dedicated devices (RFID controllers). Rfid tags, like any RFID transponder, are composed of a silicon chip and an antenna assembled on a special support and they have the task of identifying objects or people, in a unique and automatic way.

射频识别标签,提供卷,can be printed and coded by means of special printers with thermal transfer technology or direct impression. There are many variables and possibilities of choice / customization within the world of Smart Labels: our productions guarantee a high degree of flexibility in every aspect: available frequencies, chips, formats, sizes, materials, prints and coding. RFID tags can be produced in RFID tags HF 13.56Mhz frequency (ISO14443 or ISO15693), RFID tags UHF 860-960Mhz, or in double frequency for special applications.

The HF 13.56 MHz band is considered the universal band and it is used worldwide for applications such as access control, identification, payment, baggage control, laundry and library management, etc.. The latest generations of chips for this type of TAG support the anti-collision function that allows the reading/writing of multiple tags simultaneously present in the field of the Reader. Unlike in the UHF band, the 13.56 MHz RF field is not particularly affected by water or human body tissues. RFID tags HF operate at 13.56 MHz and it can be ISO/IEC 14443 or ISO/IEC 15693. The ISO/IEC 14443 standard is defined as “proximity” and covers reading distances of up to 12cm; this standard is that of NFC technology implemented in most smartphones and tablets. The ISO/IEC 15693 standard is defined as “vicinity” and covers reading distances up to a maximum of 130cm.

The RFID tags UHF band is the most recently introduced and it is the preferred band in logistic and asset management areas. The reading distance is significantly greater than HF tags one, with a reading range of up to 12-15 meters but, in exceptional cases, touching even 30 meters. The reading distance of RFID tags UHF is heavily influenced by the transmission power of the reader, the size of the tag’s antenna and the characteristics of the environment. Metal and liquids, in fact, attenuate the signal thus reducing the communication range. The tag-controller coupling occurs by electromagnetic means, in HF tags mainly by magnetic field, while in RFID tags UHF the prevailing component is of electric type. The reference standard is ISO/IEC18000-6 Type C and the communication protocol between tags and controllers is called ‘EPC “Class1/Generation2”. The anti-collision system is even more optimized, allowing multiple readings, which exceed 100 tags per second.
