The following paragraph focuses on Identive CLOUD 4510F Reader Module few specifics of contactless communication to outline usage recommendations in order to ensure best user experience. User credentials 2 are made of a contactless integrated circuit chip connected to an antenna User credentials can take several form factors: The generated current is proportional to the magnetic flux going through the antenna of the user credential Data exchange The carrier frequency of the magnetic field is used as a fundamental clock signal for the communication between the reader and the credential. It is also used as a fundamental clock input for the integrated circuit microprocessor to function. To send data to the user credential the reader modulates the amplitude of the field. To answer the reader, the integrated circuit card of the user credential modulates its way of loading impedance the field generated by the reader.

The presence of conductive materials like metal in the vicinity of the reader and the user credential can significantly degrade the communication and even make it impossible. The magnetic field of the reader generates Eddy or Foucault s currents in the conductive materials; the field is literally absorbed Identive CLOUD 4510F Reader Module that kind of material. A minimum distance of 2. To prevent the fields of adjacent readers to interfere with each other, a minimum distance between readers of 2. The presence of multiple user credentials in the field also interferes with the communication.

When several user credentials are in the field of the reader, load of the field increases which implies that less energy is available for each of them and that the system is detuned. For this reason, Identive has implemented in its driver only one slot.

Parameters like the geometry Identive CLOUD 4510F Reader Module especially the relative size of the reader s and credential s antennas directly influence the inductive coupling and therefore the communication. CLOUD 45x0 F was designed and optimized to function with user credentials of various technologies and sizes. In order to optimize the coupling between the reader and the credential, it is recommended to put both antennas as parallel as possible to each other In order to optimize transaction speed between the reader and the card it is recommended to place the credential as close as possible to the reader.

This will increase the amount of energy supplied to the user credential which will then be able to use its microprocessor at higher speeds 3. The application-specific logic has to be implemented by software developers on the host Applications provided by Identive Identive does not provide payment or transport applications or PKI or CAC applications.

There are many tools provided; here are two of them: It is an easy to use tool to configure NFC forum tag demonstrations rapidly, available in our web shop. Smart card commander version 1. This tool is as well part of all our SDKs and available as a stand-alone product. The flash can be upgraded once the device is deployed in the field, hence enabling firmware upgrades to add and potentially patch features.
