If Dad’s an international traveler, he could probably use a travel documents organizer to make navigating customs easier. This organizer from Travelon has the added bonus of protecting his passport from unauthorized RF scanning. The RFID-blocking Safe ID Ripstop Boarding Pass Neck Wallet measures just 5.5″ x 4.5″ x 0.5″ when folded, and it comes with a neck strap so your documents are always at the ready. There are pockets inside for tickets, the passport, and a photo ID, plus a coin/currency pocket and a pen for filling out customs documents. A mesh pocket on the back holds things that don’t need to be protected from unauthorized scanning. The Safe ID is available in blue or gray for $18.
