- Product Introduction
It is a kind of work produced by Philips Company A contactless smart tag card chip with a frequency of 3. This chip is a series of radio frequency identification chips newly developed and designed for logistics system applications such as parcel delivery, air luggage, rental services, and retail supply chain management. The tag chip uses protocol standards that comply with and/or the etched or stamped coil can be operated by the chip within a line of sight (such as the width of the access gate) without the use of batteries, so it can be designed for long-distance applications.
The chip has an anti-collision function, which allows the simultaneous operation of more than one tag card in the antenna field. The anti-collision algorithm selects each tag individually and ensures that one selected tag correctly performs the data exchange without data errors caused by other tags in the field. When the smart tag is placed in the electromagnetic field of the reader-writer antenna, the data transfer rate allowed by the R communication interface can reach b/.
