* The Half Card Reader can read half of a fully encoded card, however, the likelihood of errors going
undetected increases dramatically when the LRC is not read. When using LRC, the odds of an error
going undetected are about 1 in 10,000 reads compared to about 1 in 7 reads when no LRC is present.
For this reason, MagTek does not recommend reading cards that exceed the Half Card Reader's
maximum number of characters.
