if you need to write a dump the only way is to use the DEFTUNE software that is created by the makers of the MSRX6 which is the best and most popular device to write track 1 and 2 on all cards.
NOTE that there is no such thing as EMV chip encoding or decoding and all software is a scam
the only way dumps are written is by the mag stripe and DEFTUNE software is free on there website.
