The msr have 3 tracks which you have to fill correct so you will get a working card. You can start buy write some invalid dumps on card and then read them to verify if your dumps was written on the card. Personal i use a msr206,as you can see is not an expansive machine but i can tell you that it is good enough for write any kind of dump on a card.Msr has a read function and a write function.
Who ever want to work dumps with or without pin must first get an msr.The msr is a magnetic reader and writer machine which will allow you to read the data from a credit/debit card or to write some data on a magnetic strip card.A msr price is between $300 to $1000 but even a cheap msr will work just fine.Once you buy the msr you must run the software program in your computer.When you had installed the program you can start to test the machine.First you can play with any card and see what is going on.Before you start to write the valid dumps you will need to practice writing because the small mistakes will make the card to not work.
