[thhii]

I have dumps with t1 + t2
4147202219783915=180620110000714
B4147202219783915^SANDRZYK/MARK^1806201100001100000000714000000
I swiped and charged approved.
I changed t1 into
B4147202219783915^NEW/NAME^1806201100001100000000714000000
After that, swiped card response declined, can not make transaction.
I changed t1 into before
B4147202219783915^SANDRZYK/MARK^1806201100001100000000714000000
And i can swiped card normal.
Who can tell me the reason ?
When i generation t1 from t2, do t1 need digit "B" at first ?

All ways put B in tne beginning its better

what happens is that the bank recognizes the name of the account holder , in some cases it has happened to me when working track of usa

it is best to use b in front of the track with no name
