Required characteristics for images (front and back).

Characteristic Description
Focused The images must be focused and show readable information for the correct execution of the OCR process.
Brightness The images must not show glare of light, excess brightness or contrast alterations that cause error in the validation of authenticity.
Quality The documents must have legibility characteristics, not be altered, not present physical damage or alterations that prevent the reading of the information and execution of the validations.
Figure The image should preferably be in the shape of a rectangle, where only the credential is shown without excessive background. Likewise, for both sides of the document.

TuID.init method instance

Method instance that calls the SDK.

  "Your ApiKey", 
  new TuID.INEValidation(true,true,true,true,true)


The TuID.init (Context ctx, Boolean showTutorial, Boolean showResults, method m) method receives 5 parameters:

Context ctx: refers to the context from where this method is called, example (this, getApplicationContext ())
Boolean showTutorial: “true” if you want to show how the SDK works and “false” not to show the tutorial.
Boolean showResults: “true” if you want to show a view with the results of the SDK and “false” to not show the results view. • Method m: refers to the method to which the request will be made.
m.INEv2: method that validates INE (returns validation result).
TuID.INEValidation: Class instance for validation of (Info, Quality, Patterns, Curp, Face).

onActivityResult method instance

Method required to get the data from the SDK.

protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {  
  super.onActivityResult(requestCode, resultCode, data);  
  if(requestCode == TuID.AUTHID_ACTIVITY_RESULT){  
    if(resultCode == RESULT_OK){  
      Bundle extras = data.getExtras();  
      assert extras != null;  
      Boolean status = extras.getBoolean("status");  
      String response = extras.getString("response");  
      String error = extras.getString("error");  
      Uri ineFPath = extras.getParcelable("inefPath");  
      Uri ineBPath = extras.getParcelable("inebPath");  
      Bitmap bitmapF = null;  
      Bitmap bitmapB = null;
      //Get images that are use for validation  
      try {  
        bitmapF = MediaStore.Images.Media.getBitmap(this.getContentResolver(), ineFPath);  
        bitmapB = MediaStore.Images.Media.getBitmap(this.getContentResolver(), ineBPath);  
      }catch (IOException e) {  
      //Check validation status
      if (status == false) {
        Toast.makeText(getApplicationContext(), error.toString(), Toast.LENGTH_SHORT).show();  
      } else {  
        Toast.makeText(getApplicationContext(), response, Toast.LENGTH_SHORT).show();
