To use $this->input->post() initialize the form helper. You could do that by default in config folder's autoload.php.

include form in the the array.

$autoload['helper'] = array('form');

and use .serialize() instead of serializeArray()

$.ajax({
            url: base_url+"process_redeem_check",
            data: $("#formId").serialize(),
            type: "POST",
            dataType: "json",
            contentType: "application/json",

And then check you datas your are getting or not

public function process_redeem_check()
{
    $input = $this->input->post();
    print_r($input);exit;


}
