Could foul things up the next time you try to leave the country by air and and the airline swipes your passport for APIS purposes prior to boarding pass issuance.
(Or are all U.S. land border stations swiping individual passports/WHTI-complaint documents for each and every traveler nowadays?)
Food for thought and for reconsidering the overblown "trying to smuggle the 3 year old" comments.
BTW, RFID is a wonderful technology for applications of this nature, and widely deployed at the land borders.
Some small crossings cannot swipe and still write down passport numbers or just wave through... my aunt crossed at one a few days ago (to her surprise, re: writing the numbers down) and I crossed at one a couple of months back where they just looked and waved me on. Just an added fyi... fwiw.
