Transfer Data

You may transfer any data that can be represented by the array of bytes.

Example data

Let’s imagine that we want to transfer login data about the user to a different device without showing the data to the user.

Data class that represents the structure

struct TransferData: Codable {
    let userID: String
    let name: String
    let token: String
    let timestamp: String
}

Serialized Data To Transfer

{"userID":"1862","name":"John Doe","token":"72f828a0-e3a1-4691-ad99-d5a401bf5d5d","timestamp":1706534397}

Final QR code

The string above is then:

1. Turned into a byte array.
2. Encoded with the SDK.
3. Encoded data transformed into a Base64 string.
4. The Base64 string is encoded to the QR code (medium correction level).

The final QR code for such data might look like this:
