The worst case scenario is company B steals company A's number. This results in company A getting additional payments.
Or perhaps company C, seeking to ruin the reputation of company A, sets up a fake 'A' storefront with customer service that doesn't shower.

Stealing the code would give you nothing, since it won't authenticate unless you're physically in the correct location. It matches the three authentication factors: what you own (the phone and the app), what you know (the code on the stamp), and what you are/do (where you are physically). It's straight up multi-factor authentication from where I'm standing.
