Development of an RFID transceiver system

The customer solution from EPSILON is to offer cost-effective RFID labels, costing in the range of a few cents for large quantities, as data carriers and identifiers on ink cartridges. The RFID labels are designed in such a way that the stored information can be read when inserted into a printer. Parameters such as serial number, type of ink, best-before date, level, etc. can be stored. In the inserted state, a cyclic updating of the parameters is possible. The corresponding receiver and transmitter module is located in the industrial printer. The maximum range depends on the transmission power and the mechanical environment. In the reference application, operation is deliberately restricted to a limited distance of 3cm.

Concept

Conceptual design from the feasibility study to the serial device. Coordination and elaboration of the technical specifications.
