There is no doubt that mobile retailing will be one of the most preferred means for transactions amongst the 4 retail channels , but NRF's prediction that it will capture about 8% of the total e-commerce market by 2015 is a bit optimistic but its best to wait and watch.
Countries such as Germany, Denmark, Japan are already piloting successful projects wherein consumers can check out of stores directly after stocking what they need while payments are automatically debited through their mobile phones.
