When it comes to holiday gift shopping, no category of purchasable goods offers quite as much promise as personal technology. It’s now a standard go-to. Don’t know what to get dad? How about some tech? He loves tech. Don’t we all? Well, sometimes. For as much convenience and life-enhancing gee-whizardy as technology can offer, it can just as easily introduce complexity—or worse, risks to our privacy or personal security. This gift guide offers a run-down of tech gifts for the already-savvy people in your life who care about security and privacy.

RFID-blocking wallets are a fashion-conscious approach to this wireless security conundrum. Using a special material designed to block such radio frequencies, these otherwise normal-looking wallets prevent any such data-skimming from taking place.
