Radio Frequency IDentification (RFID) tags and readers are a category of low-end wireless devices that people may not recognize as forming a computer network. Which of the statements below are true about RFID?

i. RFID technology takes many forms, used in smartcards, implants for pets, passports, library books and more
ii. with the EPC (Electronic Product Code) RFID tags are small, inexpensive devices that have a unique identifier and a small amount of memory that can be read and written by an RFID reader
iii. the tags are the intelligence in the system, analogous to base stations and access points in WiFi networks
iv. in the EPC Gen 2 Physical Layer the data is transmitted in the same way as in all other wireless situations we have seen so far
