Second in my opinion its better to develpe the POS machine instead of cards, and unique card nunber can be linked with multi card issuer companies with the differert card and at the time of swaping, machine will give the option of choosing the card type and the company.

But then I realized that the more logical (and practical) approach is to implement such features into cellphones (as previously stated).
Why would companies world-wide want to upgrade all of their swiping credit systems for this device…when you could implement this device into a cell-phone a year later…and another upgrade would be needed.
In order for this all-in-one mentality to catch on: it simply needs to be on your phones.
