#### Properties
| Name | Type | Usage |
| ---- | ----------- | ----- |
| `isConnected` | `Boolean` | Indicates whether an eChip Reader Device is connected |
| Name | Usage |
| ---- | ----- |
| `isConnected: boolean` | Indicates whether an eChip Reader Device is connected |
#### Methods
| Name | Usage |
| ---- | ----- |
| `onConnect(Listener<EChipReader>): Disposable` | Adds an event listener for when an eChip Reader Device is connected. Callback method will be passed the new `EChipReader` instance for the connected device. |
| `start(): Promise<void>` | Initializes the watcher by first requesting permissions and then doing a hardware search. This method must be triggered by a user action such as a click event or the permission request will be denied. |
| `stop(): Promise<void>` | Closes all active connections. |
### EChipReader
The `EChipReader` instance is passed into the `onConnect` callback function and is the interface to the connected eChip Reader Device.
#### Properties
| Name | Parameters | Return Type | Usage |
| ---- | ---------- | ----------- | ----- |
| `onConnect` | `Listener<EChipReader>` | `Disposable` | Adds an event listener for when an eChip Reader Device is connected |
| Name | Usage |
| ---- | ----- |
| `claimed: Promise<boolean>` | Promise indicating if the USB device interface has been claimed. |
| `disposed: boolean` | Indicates if the device connection has been severed and the class instance disposed. |
#### Methods
| Name | Usage |
| ---- | ----- |
| `onDisconnect(Listener<null>): Disposable` | Adds an event listener for when this eChip Reader Device becomes disconnected. The instance will be disposed following this event. |
| `onEChipDetect(Listener<EChip>): Disposable` | Adds an event listener for when an eChip is connected to the eChip Reader device. Callback method will be passed the new `EChip` instance for the connected eChip. |
### EChip
The `EChip` instance is passed into the `onEChipDetect` callback function and is the interface to the connected eChip device.
#### Properties
| Name | Usage |

| `disposed: boolean` | Indicates if the eChip connection has been severed and the class instance disposed. |
#### Methods
| Name | Usage |
| ---- | ----- |
| `destroy(): void` | Called to disconnect the eChip device. |
| `onDisconnect(Listener<null>): Disposable` | Adds an event listener for when this eChip becomes disconnected. The instance will be disposed following this event. |
| `getData(): Promise<EChipObject>` | Promise resolves with an `EChipObject` representing the data on the eChip. |
| `clearData(): Promise<EChipObject>` | Method clears the data on the eChip and resolves with an `EChipObject` of the new blank eChip data. |
| `setData({string: MachineObject}): Promise<EChipObject>` | Method sets the data on the eChip according to the data passed into the method. The method accepts an object with `string` keys corresponding to the machine's 4-digit model number with the `MachineObject` as the value of the property. |
