How do I interpret the response from GETTING HANDLING OPTIONS?
I am communicating with a Visa Electron debit card through an ACR reader and I am getting the following response from the team GET PROCESSING OPTIONS
:
80 0A 1C 00 08 01 03 00 10 01 01 00 90 00
How to interpret this answer when there is no AFL (Application File Locator) or AIP (Application Interchange Profile)? Here's the complete message log:

The EMV specification can help you in detail. The response contains only tags 0x82 and 0x94 values without the tag and length parts.
In the response, Get the processing parameter (GPO) BER-TLV . In your example: in tag 0x80 "Template, response response format 1" packed tag 0x82 "EMV, application exchange profile (AIP)" 2 bytes and the remainder Tag 0x94 "EMV, Application Locator (AFL)".
Here are the results with EMV APDU command / response parser
