# Creating invisible digital signatures in Android

It isn’t possible to create digital signatures without a signature form field. A [`SignatureFormField`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.forms/-signature-form-field/index.html) for signing is always required, but it can have an empty bounding box, making it invisible:

### KOTLIN

```kotlin

// Create an empty rect.
val rectFSignatureFormConfiguration = RectF(
    30f, // left
    190f, // top
    30f, // right
    190f // bottom
)

val signatureFormConfiguration = SignatureFormConfiguration.Builder(0, rectFSignatureFormConfiguration).build()
val signatureFormField = document.formProvider.addFormElementToPage("signaturefield-1", signatureFormConfiguration) as SignatureFormField

// Now perform the digital signing with the newly created form field.
performSigning(signatureFormField)

```

### JAVA

```java

// Create an empty rect.
RectF rectFSignatureFormConfiguration = new RectF(
    30, // left
    190, // top
    30, // right
    190 // bottom
);

SignatureFormConfiguration signatureFormConfiguration = new SignatureFormConfiguration.Builder(0, rectFSignatureFormConfiguration).build();
SignatureFormField signatureFormField = (SignatureFormField) document.getFormProvider().addFormElementToPage("signaturefield-1", signatureFormConfiguration);

// Now perform the digital signing with the newly created form field.
performSigning(signatureFormField);

```
