use credit card readers that plug into the headphone jack (red arrow) in the mobile device, which accepts microphone input. When the card is slid through the reader, it converts the digital data in the magnetic stripe to analog tones similar to an analog modem for dial-up telephone lines...
A modem, or data set, is a device that converts the digital signals produced by computers and terminals into analog signals that telephone circuits are designed to carry and then back to digital signals at the other end of the communication link. See also analog-to-digital conversion. 展开 ...
A typical telephone modem makes use of ADC to convert the incoming audio from a twisted-pair line into signals the computer can understand. In a digital signal processing system, an analog-to-digital converter is required if the input signal is analog. What is the Nyquist theorem and why is...
