Smart Label Technology - BiStatix

Recently, Huamin Smart Card Systems introduced a new advanced technology, BiStatix. BiStatix ​​is ​​a low-cost wireless identification (RFID) technology developed by Motorola, which provides a breakthrough solution that combines the low cost of barcodes and automatic data collection. This technology can replace bar codes and traditional RFID for postal mail tracking detection, airline baggage tracking detection, and commercial product management. BiStatix ​​took advantage of Motorola’s patented dual technology data reception, allowing the simultaneous use of traditional bar code systems, new BiStatix ​​enhanced bar code labels, and single BiStatix ​​tags. In addition, BiStatix ​​can be easily applied to current bar code devices.

Basic Principles - BiStatix ​​has a reader that can generate energy at a predetermined frequency and rely on the "energy field" to receive information. The reader emits a continuous RF signal. When the smart tag approaches the reader, the printed antenna on the tag can receive the RF signal from the reader. The printed antenna transmits the RF signal to the silicon integrated circuit on the tag. The circuit then transmits its own recorded information to the reader, which uploads the information to the host of the management system. In this process, the reader can also add, modify or delete the information in the tag according to the requirements of the host.

----As a sensing system, BiStatix ​​works by capacitive coupling, but it does not require the traditional wireless coil, but uses two printed electrodes attached to the integrated circuit (IC). The two electrodes collect the excitation signal, generate a (working) voltage through the IC circuit, so that the IC can work, and transmit the pre-programmed data to the data receiver, which is decoded and transmitted to the terminal computer. This is basically the same as a traditional RFID system.

The BiStatix ​​system has two data receivers: unipolar and bipolar. In a single-stage system, the data receiver uses a single antenna to transmit the excitation signal. When the tag is presented to the data receiver, the electrode near the excitation signal will direct the current through the chip to another electrode that is coupled to the plane. This plane can be Things such as "trays or trays" can also be cardholders. In bipolar systems, the data receiver is used to transmit and receive excitation currents, and the tag must be placed in a reasonable position on the receiver so that the tag antenna can "see" couple to the corresponding antenna located on the data receiver. The tag antenna can be supplied with operating voltage; next, data is transmitted from one electrode of the tag to the receiving antenna of the data receiver.

Application Features - BiStatix ​​utilizes a silicon chip-based design technology that discards expensive components to reduce costs. Of course, bar codes with the addition of BiStatix ​​are always more expensive than simple bar codes, but BiStatix ​​is ​​definitely the lowest-cost RFID technology that can be added to bar codes.

The technology has a simple manufacturing process. It uses a carbon ink antenna and has abandoned some expensive processes such as coil winding, label generation, etching, and IC integration.

BiStatix ​​labels can be printed on a variety of print carriers, for example it can be printed on insulating paper, plastic, wood, textiles or glass. If the print carrier is damaged, such as tearing, crumpling, etc., it will not affect its work, and data can be read from any angle and direction. Therefore, it is hardly limited by size and space and is more economical and practical.

In addition, BiStatix ​​uses the traditional screen printing and conversion process in label manufacturing, abandoning the complex process of coil winding and metal deposition, and replacing it with a simple flip-chip die-bonding process based on common materials. In this way, the production process is simple and can guarantee high reliability and productivity.

The silicon chip of BiStatix ​​core chip can be very thin. In fact, the size of the chip is less than 250μm, and the entire surface area of ​​the chip is less than 3mm2. It can be applied to places that are not easily detectable, at least not prominent.

Currently, BiStatix ​​technology has been successfully applied around the world. It is believed that in the near future China will have the practical application of BiStatix ​​technology.
