Universal Asynchronous Receiver/Transmitter or UART for short represents the hardware - integrated circuit, used for the serial communication through the serial port. But unlike long range RFID, NFC is intentionally limited to short proximity for improved security. In this standard, data are sent over a single line from a transmitting device to a receiving device in bit serial format at a prespecified speed, also known as the Baud Serial communications involves sending data one bit at a time. With Bluetooth, for example, you may need to pair devices before they can communicate with each other, which can be cumbersome. It was originally designed by Philips Semiconductor in 1982. Essentially, data is transmitted in one way, 1 bit at a time, from sender to receiver. If your Touchatag or ACR122 device fails being detected by PCSC-lite daemon (pcsc_scan doesn't see anything) then try removing the bogus firmware detection of libccid: edit libccid_Info.
