A. Camouflage
B. Signal blocking
C. Proximity readers
D. Reflective glass
E. RFID
F. Bollards

正解: C,E

解説:
RFID is an acronym for "radio-frequency identification" and refers to a technology whereby digital data encoded in RFID tags or smart labels (defined below) are captured by a reader via radio waves.
Proximity readers work by constantly emitting a short range radio frequency (RF) field. When a proximity card comes within range of this field, an integrated chip within the card is powered up and the chip transmits a card number back to the reader. Not all proximity cards are born equal though, and it is important that the differences are weighed up when making a decision about which technology to adopt.
