I'm communicating with a Visa Electron debit card via an ACR reader and I get the following response from the GET PROCESSING OPTIONS command:
80 0A 1C 00 08 01 03 00 10 01 01 00 90 00
How should I interpret this response, when there's no AFL (Application File Locator) nor any AIP (Application Interchange Profile) in it? Here's the full communication log:

Thanks a lot!
EMV specification can help you about details. In the response Only Tags 0x82 and 0x94 values without tag and length parts.
In the Get Processing Option (GPO) Command response BER-TLV encoded data. In your sample: Under Tag 0x80 "Template, Response Message Format 1" packed Tag 0x82 "EMV, Application Interchange Profile (AIP)" value 2 bytes and rest is Tag 0x94 "EMV, Application File Locator (AFL)" value.
Here are results with EMV APDU command/response parser
