In addition to a conventional NFC contactless interface, the new dual-interface NFC Forum Type 4 Tag also provides a one-wire interface that allows the tag to provide a wireless communications bridge between two devices.
With the new tags, a tap of an NFC phone to a Bluetooth wireless headset containing one of these tags can initiate the pairing operation. The tag detects the NFC field on the contactless interface and sends a pulse over the one-wire interface to the controller inside the headset to start the pairing process.
This same kind of field sensing could be used to establish Wi-Fi connectivity for the first time between an NFC device, such as a tablet, and a new wireless access point, or to start transferring data, through the tag, between the NFC and host devices.
The dual-interface NFC Type 4 Tag is offered in two memory configurations. The VaultIC 151D offers a 1.5-Kbyte file system size, while the VaultIC 161D has a 16-Kbyte file system size. Each tag integrates a standard contactless interface with full ISO14443 Type B protocol support for communicating with NFC devices and an INSIDE Secure proprietary one-wire interface for connection to a host processor. Accessing the data contained within the file systems from either interface is performed using the standard NFC Forum command set.
In recent news, Inside Secure has named US-based technology sales firm BP Sales to represent the company’s product offerings in Mexico.
