IBM is working with Visa to produce a shoe-based mobile payments system. Users can turn shoes into a mobile point of sale system and a secure payment gateway. With this idea, users can go everywhere without a wallet and pay for goods with wearable devices.
In my option, it looks like this shoe-based mobile payment is convenient. However, this method of payment is hard to view and operate. Unlike using a smartphone, you can view the amount to pay and accept the payment thought figure prints. This show-based mobile payment does not have a security protection. Anyone can wear this kind of shoes to make payments. Most people will have problems to accept this method and contact with auto-bill-pay. Overall, I think this approach is overreaching. The mobile-payment market will have a longer time to adopt this method.
