@TK This is quite misleading :)
a) "DAN" is not a thing - DPAN is
b) Tokenised cards are stored in a TPM on Android devices in the same way as on Apple. The TPM is required to "emulate" an EMV card during a IRL transaction.
c) In the e-commerce flow, it's correct that Google is providing the tokenised PAN. However, you're missing the part where the card scheme provide data back to the mobile wallet provider to power "recent transactions". So the data is available anyway.
