displaying details from magnetic card reader

hello people

new here and new to electronics and arduino. ive been messing around with a magnetic card reader
which has rs232 output ive opened up the module and it has a ttl to rs232 converter chip on board.

can i get the ttl before it goes into the rs232 driver and connect to arduino?

what would the sketch be?

thanks in advance

Yes. Find the datasheet for the chip and figure out which pins are inputs.

That depends on what data the reader sends. You need to know the baud rate. I would use SoftwareSerial to read from the card reader and use Serial to send that data to Serial Monitor to read.

thanks john

thats all i needed to know
