The Biometric Daily

Paying with your finger is the latest hit at your local grocery. Two companies, Pay By Touch & BioPay, rival for the customers favor. The business model for both companies is the same; trying to obtain as many user(templates) possible and tie them to the individuals financial information as provided at enrollment.
The actual payment is simply done by typing the number provided during enrollment and a simple fingerscan on the biometric paymenterminal.
Questions has been raised about the security of these biometric payment method's, but apparently the public doesn't care. Biometric convience is hot and consumers want it. Pay By Touch recently raised $130mln for further expansion.
Which problems will these companies face in the near future?
The first biometric "hack" will blow a big hole the corporation's security image. Although both concepts use a 2-factor authentication (something you know and something you are) I expect that the system will be hacked in the near future.
The second problem both companies will face is that the jump to Europe will turn out to be too far. Since most European countries have very sophisticated smartcard based payment systems, there is no direct customer need to fulfill.
The third problem will be that customers will ask for interoperability between the various systems in the near future. The only way that this can be achieved is either through exchange of vital information (templates/ID) or through adapting the various terminals and re-enrollment of all users.
I welcome these initiatives but I do not think both systems will turn out to be the de facto standard for biometric payments.
