## VASMode
This enum refers to the Apple VAS and Google Wallet VAS mode. This controls how the VAS data is returned in the transaction ARQC. For details on Apple VAS data structure returned in a transaction see *D998200383 DynaFlex Family Programmer’s Manual (COMMANDS)*.
| Enum | Description |
| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Single | The device reads only VAS data from a tapped smartphone, or reads EMV payment data from a tapped card. When the device sends ARQC to conclude the transaction, it only includes either EMV payment data in container FC for cards, or includes VAS data in container FE for smartphones. |
| Dual | The device reads both VAS data and EMV payment data from a tapped smartphone, or reads EMV payment data from a tapped card. When device sends ARQC to the host to conclude the transaction, it includes EMV payment data in container FC and includes VAS data, if available, in container FE. |
| VASOnly | The device reads only VAS data from a tapped smartphone, and does not read data from a tapped card. If the tapped smartphone does not support VAS, the device does not detect or read from the smartphone. When the device send ARQC to conclude the transaction, it includes VAS data in container FE and does not include EMV payment data in container FC. |
| PaymentOnly | The device operates the same as EMV mode. It reads only EMV payment data from a tapped smartphone or a tapped card. When the device sends ARQC to conclude the transaction, it includes EMV payment data in container FC and does not include VAS data in container FE. |
| ECP2 | The host can configure the ECP2 frame. See Apple ECP2.0 specification. |
## VASProtocol
This enum refers to the Apple VAS protocol. For details on Apple VAS data structure returned in a transaction see *D998200383 DynaFlex Family Programmer’s Manual (COMMANDS)*.
| Enum | Description |
| ---- | ----------------- |
| URL | URL VAS protocol |
| Full | Full VAS protocol |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://developer.magtek.com/sdks-and-tools/universal-sdk-documentation/android/enumerations/enumerations-f-v.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
