rememberPCIFieldState

Creates a new instance of PCIFieldState that is remembered across recompositions.

Important: This state is NOT preserved across process death or configuration changes (e.g., screen rotation). This is intentional for PCI DSS compliance — sensitive card data (card number, CVV, expiration date) must never be serialized to Bundle or disk.

To preserve state across configuration changes, host PCIFieldState in your ViewModel instead:

class PaymentViewModel : ViewModel() {
    val cardNumberState = PCIFieldState.create()
    val expirationDateState = PCIFieldState.create()
    val securityCodeState = PCIFieldState.create()
}

@Composable
fun PaymentForm(viewModel: PaymentViewModel) {
    CardNumberTextField(state = viewModel.cardNumberState)
    ExpirationDateTextField(state = viewModel.expirationDateState)
}
