# BarcodeAnchor A barcode’s position in a person’s surroundings. ``` struct BarcodeAnchor ``` ## Overview A `BarcodeAnchor` describes a barcode that ARKit detects in a person’s surroundings. A barcode anchor has exactly one that indicates which type of barcode the framework detects. It also includes properties, such as the barcode’s payload data, which is a decoded string value of that data. ## Topics ### Getting barcode information [`var extent: SIMD3`](/documentation/ARKit/BarcodeAnchor/extent) The extent of the detected barcode’s bounds. [`var originFromAnchorTransform: simd_float4x4`](/documentation/ARKit/BarcodeAnchor/originFromAnchorTransform) The transform from the barcode anchor to the origin coordinate system. [`var payloadData: Data`](/documentation/ARKit/BarcodeAnchor/payloadData) The encoded payload data of the detected barcode. [`var payloadString: String?`](/documentation/ARKit/BarcodeAnchor/payloadString) The decoded payload string value of the detected barcode. [`var symbology: BarcodeAnchor.Symbology`](/documentation/ARKit/BarcodeAnchor/symbology-swift.property) The symbology of the detected barcode. [`enum Symbology`](/documentation/ARKit/BarcodeAnchor/Symbology-swift.enum) Values that describe specific kinds of barcodes. [`var id: UUID`](/documentation/ARKit/BarcodeAnchor/id) The unique identifier of an anchor. ### Instance Properties [`var description: String`](/documentation/ARKit/BarcodeAnchor/description) A textual representation of this anchor. ### Default Implementations [ARKitCoordinateSpaceProviding Implementations](/documentation/ARKit/BarcodeAnchor/ARKitCoordinateSpaceProviding-Implementations) ## Relationships ### Conforms To [`CustomStringConvertible`](/documentation/Swift/CustomStringConvertible) [`Identifiable`](/documentation/Swift/Identifiable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Anchor`](/documentation/ARKit/Anchor) [`ARKitCoordinateSpaceProviding`](/documentation/ARKit/ARKitCoordinateSpaceProviding) [`Escapable`](/documentation/Swift/Escapable) [`Copyable`](/documentation/Swift/Copyable) [`Sendable`](/documentation/Swift/Sendable) --- Copyright © 2026 Apple Inc.
