# pinMessageIndices

A list of message indices referring to a predefined message table, used to specify the type and number of messages displayed during the PIN operation. `nil` by default.

```
var pinMessageIndices: [NSNumber]? { get set }
```

## Discussion

If `nil`, the reader does not display any message (reader specific). Typically, PIN verification takes 1 message; PIN modification takes 1 – 3 messages.
