Slightly dated (by a week), but, illustrative: http://www.cnn.com/2015/08/29/politics/chris-christie-fedex-packages/ He seems to be confusing short-range RFID or readable barcodes used on packages, and, (say) ankle bracelets used for people on probation/waiting trial/heavily-supervised-parolees. Does Christie really want all tourists to put on ankle bracelets? But, seriously, that isn't what this is about. It is another gratuitous xenophobic attack on "immigrants". Christie wants to keep up with the Joneses, politically-- Trump has gotten a lot of mileage out of his xenophobic ranting, and, Christie wants some of it for himself. Revolting.
