Here is an interesting article speculating (rumor) that Apple might be considering getting into the P2P (Peer to Peer) mobile payment service. Of course, Apple has the program "Apple Pay" presently, which links payment to your credit card. This P2P payment system would presumably link payments to your debit card which debits your bank account directly. I'm not a fan of anyone, or business, having direct access to our bank account via a debit. I like the idea of a middlemen -- like a bank -- where my exposure is limited to $50 for fraudulent use. I would need a lot more understanding about this mobile payment service from Apple, if it should come to fruition, before using it.
Nonetheless, technology changes and progresses, and it will be interesting to see if this concept does, in fact, materialize.
