After the host issues the Arm-to-Read command, the UIC680 will check if any payment card is
detected in the reading zone or any magnetic stripe card is swiped (the magnetic stripe reader
is optional device). No matter the card is decoded successfully or not, it will return the ‘^’ to
indicate that the card has been read. The host can issue the ‘Q’, ‘R’, ‘S’ commands to retrieve
the card data accordingly.
