Bling Nation is looking to change that with its service, which pairs RFID-enabled stickers with a back-end system that charges purchases to credit cards (via PayPal) and sends text-message receipts to cellphones.
Their automated system replicates the functions normally performed by customs and immigration officials, and uses biometric face recognition and ePassport RFID registration to process trusted travelers much more rapidly and efficiently than standing in line to be personally checked, especially during peak travel times.
