Performance characteristics:

1. Can read and write multiple tracks simultaneously (tracks 1-3);
2. Under normal circumstances. Magnetic stripe passbooks use track 2, while ATM cards use track 3. Reading and writing tracks 2 and 3 simultaneously is a basic requirement for banking services;
3. Optional built-in IC card reading and writing function, which means that the same machine can be used for the magnetic stripe passbook and the electronic wallet function that the withdrawal machine will use. Now, a reader\/writer with only magnetic card function is selected, and in the future, only one IC card reading and writing module needs to be added to complete the IC card reading and writing function, protecting investment;
4. Good compatibility, can be connected to any type of terminal for use. The magnetic stripe reader\/writer device, combined with the 51X password keyboard, can form a simple and practical POS system with any brand of terminal; 5. Optional built-in or external serial port extender, easy to connect and use;
6. Provide compatible models with any magnetic stripe reader\/writer installed by the user without changing the user's application;
7. Provide programs for WINDOWS, UNIX, DOS and their development in collaboration with users;
8. Can write high resistance card extension ICs and PSAM cards;
9. The 91X series is a gold card keyboard that combines a keyboard and a reader\/writer, making it convenient for our work;
10. The gold card keyboard has AT\/XT key value conversion function.
