The idea is to write a wrapper that encapsulates all of the (related) data. This is useful in type-checked languages where changing the signature can have repercussions across multiple classes. I actually do this in javascript, too. I'll pass in object (it's nice in js because you can just write them in json) and refer to the variable by object property verifyID({idNum: 1234, surname: 'Himes', firstName: 'Dan'}); {where the signature is verifyID(idObect) } This has the advantage of not requiring you to remember the order of parameters.
