PayContactlessEmbed.getInstance().doPayWithAccount(@NonNull Double amount, @Nullable String currencyCode, @NonNull FragmentActivity activity, @Nullable Map<String, String> rfuMap, @NonNull TransactionResultListener listener)

Please set empty map value for rfuMap instead of null on SDK version 3.4.12. This issue will be fixed with the next version.

If currency parameter is set null, the default currency is used for transaction. The default currecny is Naira in SDK.
