tamper-resistant feature definition
tamper-resistant feature means a hologram or a watermark, although there may be other acceptable tamper- resistant features. We were unable to determine exactly what other acceptable tamper-resistant features might be by the time this paper was published. Moreover, in the future, the requirements for documents that will be accepted by the TSA will become more strict and a tribal photo ID which is acceptable now will probably not be acceptable when the stricter requirements go into effect. Our advice is to bring a back-up document with you when you travel (other acceptable documents include your driver's license or your passport). Please call us if you have any questions.
