COMMUNICATIONS DEVICE INCLUDING RADIO FREQUENCY (RF) SIGNAL BLOCKING LAYER FOR NEAR-FIELD COMMUNICATION (NFC) DEVICE AND RELATED METHODS |
摘要 |
A communications device may include a near-field communication (NFC) circuit device, and a radio frequency (RF) signal blocking member adhesively coupled with the NFC device. The RF signal blocking member may be configured to block RF signal communication by the NFC device while coupled therewith. The RF signal blocking member may comprise an electrical conductor. In accordance with an example, the RF signal blocking member may comprise a frangible layer. In another example, a pressure sensitive adhesive layer may be included for adhesively securing the RF signal blocking member with the NFC device. |
