The shielding article comprises a shielding component configured to prevent operation of an antenna of the device used for conducting proximity-based communications, without preventing operation of at least one other antenna of the device when the shielding component is aligned with the antenna used for conducting proximity-based communications. The shielding article may be separate from, or included in an accessory or carrying article and may be fixed or detachably coupled thereto. ## Claims ### Claim 1 A shielding article for shielding a device enabled for proximity-based communications, the shielding article comprising a shielding component configured to prevent operation of an antenna of the device used for conducting proximity-based communications, without preventing operation of at least one other antenna of the device when the shielding component is aligned with the antenna used for conducting proximity-based communications. ### Claim 2 (depends on 1) The shielding article of claim 1, wherein the shielding article is configured to be coupled to the device to enable alignment of the shielding component and the antenna used for conducting proximity-based communications. ### Claim 3 (depends on 2) The shielding article of claim 2, wherein the shielding component is movable with respect to the device to enable a first coupled position wherein the shielding component is aligned with the antenna used for conducting proximity-based communications, and a second coupled position wherein the shielding component is unaligned with the antenna used for conducting proximity-based communications to permit proximity-based communications with the device. ### Claim 4 (depends on 3) The shielding article of claim 3, wherein the shielding article is affixed to an accessory for the device. ### Claim 5 (depends on 4) The shielding article of claim 4, wherein a closure for the accessory comprises the shielding article. ### Claim 6 (depends on 3) The shielding article of claim 3, wherein the shielding article is detachably coupled to the device or an accessory for the device. ### Claim 7 (depends on 6) The shielding article of claim 6, wherein a collar sized to slide over the device or the accessory comprises the shielding article. ### Claim 8 (depends on 1) The shielding article of claim 1, wherein the shielding article is affixed to an exterior surface of an accessory for the enabled device such that the shielding component is aligned with the antenna used for conducting proximity-based communications when the device is stowed in the accessory. ### Claim 9 (depends on 1) The shielding article of claim 1, wherein the shielding article is located within an accessory for the device. ### Claim 10 (depends on 9) The shielding article of claim 9, wherein the accessory is contoured to restrict stowage of the device such that a first exterior surface of the device faces a particular direction. ### Claim 11 (depends on 10) The shielding article of claim 10, wherein the first exterior surface comprises a display screen. ### Claim 12 (depends on 10) The shielding article of claim 10, wherein the accessory is contoured to permit stowage of the enabled device such that a first exterior surface of the device can face multiple directions. ### Claim 13 (depends on 1) The shielding article of claim 1, wherein the shielding article is located within another article. ### Claim 14 (depends on 1) The shielding article of claim 1, wherein the shielding component comprises any one or more of a solid portion and a mesh portion. ### Claim 15 (depends on 14) The shielding article of claim 14, wherein the shielding component comprises a plurality of solid portions distributed within the mesh portion. ### Claim 16 (depends on 1) The shielding article of claim 1, wherein the shielding component comprises a plurality of portions, each portion configured to shield a portion of the antenna used for conducting proximity-based communications. ### Claim 17 (depends on 1) The shielding article of claim 1, wherein the shielding component comprises any one or more of a lossy material and an absorbent material. ### Claim 18 (depends on 17) The shielding article of claim 17, wherein the shielding component comprises of any one or more of a polymeric material filled with magnetic particles, a permeable material using magnetic fillers, and foam absorbers impregnated with a carbon coating. ### Claim 19 (depends on 1) The shielding article of claim 1, wherein the antenna used for conducting proximity-based communications is a near field communication (NFC) antenna and the device is enabled for conducting NFC-based communications. ### Claim 20 An accessory for a device enabled for proximity-based communications, the accessory comprising a shielding article for shielding the device, the shielding article comprising a shielding component configured to prevent operation of an antenna of the device used for conducting proximity-based communications, without preventing operation of at least one other antenna of the device when the shielding component is aligned with the antenna used for conducting proximity-based communications. ### Claim 21 A carrying article comprising a shielding article for shielding a device enabled for proximity-based communications, the shielding article comprising a shielding component configured to prevent operation of an antenna of the device used for conducting proximity-based communications, without preventing operation of at least one other antenna of the device when the shielding component is aligned with the antenna used for conducting proximity-based communications. ### Claim 22 (depends on 21) The carrying article of claim 21, wherein an accessory coupled to the carrying article comprises the shielding article. ### Claim 23 (depends on 22) The carrying article of claim 22, wherein the accessory is detachably coupled to the carrying article. ### Claim 24 (depends on 22) The carrying article of claim 22, wherein the accessory is integral to the carrying article.
