# Token Data Members

The following table lists and describes the data members of the `Token` object.

| Data Member | Data Type | Description |
| - | - | - |
| `description` | string | **Optional.** A description of this token type in your application. |
| `merchantTokenId` | string | **Required.** Your unique identifier for this `Token` object. This ID is also referred to as the token type. For example, an airline might identify a `Token` object with the ID `FREQ_FLIER_MILES_2010` to denote the number of frequent-flier miles accumulated by a customer account in 2010. A cell-phone company might use `ANYTIME_PHONE_MINUTES` to identify `Token` objects that specify a customer’s balance of anytime minutes. **Note:** use of the forward slash character (/) in merchant identifiers is not allowed. See [Merchant Identifiers](Merchant_Identifiers#) for more information. |
| `VID` | string | Vindicia's Globally Unique Identifier (GUID) for this object. When creating a new `Token` object, leave this field blank; it will be automatically populated by Subscribe. |
