Ironically, both iOS and Android have payment solutions built in, and on Apple devices this uses the secure enclave. Fingerprinting a phone is a vastly inferior solution to that.
Which is useful if you happen to live in an Apple Pay / Android Pay supported country with contactless payment widely rolled out.
However, considering contactless was pretty rare even in the US until recently, it’s wise to have other solutions - and cover other use cases like online banking, loan applications etc etc.
