Issue Reading EMV visa credit card record

I have developed an android app to read EMV chips, i was able to read most of the EVMs for visa, master , American Express. except of one visa card,its chip looks different from the others,i know EMV does not specify which files data is stored in, so what i did is reading all files and records but it always return .

SW1-SW2 6A 83 Record not found

attachment is the picture of the Emv chip .

EMV Chip For Visa Credit Card

any idea what chip type is this ?

by read i assume you refer to READ RECORD. When Application File Locator( AFL) is not available, you do not have to do READs. It is using the identifiers from ALF you are supposed to do READs.
