Thanks for the information provided. <br />I wanna ask you about something that has happened these days. <br /><br />I am sending a AMEX EMV transaction to ATS(AMEX TEST SYSTEM), but it's complaining to have an incorrect application cryptogram. So I need a way to recalculated to confirm that is good or bad. I know that ARQC is based on some input data from the terminal that are compared to the CDOL from the card. <br /><br />How can i recalculate the ARQC? <br /><br />If you have any hints about it, please let me know. <br /><br />Have a nice day.Anonymoushttps://www.blogger.com/profile/15577264426808285997noreply@blogger.comtag:blogger.com,1999:blog-3106309360391724696.post-45514607036407935142015-08-01T21:12:20.093-07:002015-08-01T21:12:20.093-07:00Really helpful as simple :) Thanks Ali bhaiReally helpful as simple :) Thanks Ali bhaiaashrafhttps://www.blogger.com/profile/01569975496190019490noreply@blogger.com
