Square says it now takes a poignant 4.2 seconds from a impulse we drop your chip until a transaction is completed. And they’d like to see that turnaround time driven down even further, to an even 3 seconds. Square does have a bit of an advantage in a space since they control both a hardware and program during Square registers, though according a New York Times, Wal-Mart also managed to save business 11 seconds only by stealing an volume acknowledgment screen.
On a other hand, as a Wall Street Journal forked out final month, all of this is pushing towards a contactless remuneration future. And, as it turns outs, chip cards were not as secure as we thought in a initial place.
