● - is a product produced by Philips Company with an operating frequency. The contactless smart label card 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 d-tag chip uses protocol standards that comply with it and is a major member of the smart label product series. The chip is simply connected with a few turns of the printed antenna (receiving or transmitting. Carrier frequency). The etched or stamped coil can be chipped on. It operates within a sight distance (such as the width of an access control gate) and does not require the use of batteries, so it can be designed for long-distance applications.
● The d chip has an anti-collision function that allows more than one tag card to be operated in the antenna field at the same time. The anti-collision algorithm selects each tag individually and ensures that one selected tag correctly performs the data exchange without causing data errors due to 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 communication interface can be achieved.
