# isConcatenated

Whether this object represents a concatenated QR Code payload consisting of two or more underlying payloads. If YES, then:

## Declaration

```swift
var isConcatenated: Bool { get }
```

## Discussion

Discussion The constituent payloads are exposed in the subPayloads property. Properties other than subPayloads and qrCodeString (e.g. vendorID, discriminator) are not relevant to a concatenated payload and should not be used. If accessed, they will act as if the payload was not in fact concatenated, and return the relevant value associated with the first sub-payload. Mutating such a property will discard the additional sub-payloads.
