Most stored-value cards incorporate technology which allows for contactless data transmission over short distances so the computer processor in the microchip con interact with readers and other devices.

Near field communication

Explanation:

 The near field communication is one of the type of technology in which any two devices are communicating with each other by sharing the data or any information on the basis of some communication protocols.

According to the given question, the Near field communication technology works by using the NFC microchip and with the helps in this the communication become more effective with the other devices.  

 Therefore, Near field communication is the correct answer.

hey there! :

mass = 5.75 g

volume = 7.5 cm³

therefore:

density = mass / volume

d = 5.75 / 7.5

d = 0.7 g/cm³

answer c

hope that !
