Hi @sabrirauf ,

In the documentation of EMVCo, there is no exists tag '00' in Data Objects for Additional Data Field Template (ID "62").

Name ID Format Length Presence
Bill Number "01" ans var. up to "25" O
Mobile Number "02" ans var. up to "25" O
Store Label "03" ans var. up to "25" O
Loyalty Number "04" ans var. up to "25" O

Terminal Label "07" ans var. up to "25" O
Purpose of Transaction "08" ans var. up to "25" O
Additional Consumer Data Request "09" ans var. up to "03" O
RFU for EMVCo "10"-"49" S O
Payment System specific templates. "50"-"99" S O

Ref: Data Objects for Additional Data Field Template (ID "62") page 22

I checked your data and the '00' tag is not valid, following the official EMVCo documentation.
