In this mobile payment patent: http://www.google.com/patents/US8639619, the last 2 steps of claim 1 are:
providing the token and the payment amount to the payment-processing entity, via the communication module, to cause completion of a transaction between the user and the merchant,
wherein providing the code or token alone does not enable completion of the transaction.
Why does the first step say "providing the token...to cause completion of a transaction" and the second step say "providing the code or token alone does not enable completion of the transaction"?
Having trouble understanding why the last part of claim 1 is there at all.
