Contemplated validation systems provide access to a master validator, one or more remote validators, and an authorized party such that validation using a validation script can be performed in a flexible manner that allows modifications to the script in real time. Typically, modifications are requested by a remote validator in the field where the remote validator can not answer a validation request generated by the validation script in a proper or predetermined manner. A master validator will receive the request and modify the validation script accordingly to allow the validation to proceed. Most typically, modification of the script is authorized by an authorized party.
