HighWire's voucher system allows mobile users to access subscribed content off-campus. A voucher is obtained through a publisher's website on an institution's network and applied to a mobile device within 48 hours. This grants the same access level to protected content as the institution's subscription when using mobile websites or apps. Vouchers are device and publisher specific and last 1-12 months depending on the publisher. The system provides a seamless way for mobile users to access subscribed content remotely.
