Richard Gamble writes for Treasury & RIsk Magazine about purchasing cards and a shift in how they're being used that improves their effectiveness. Gamble writes "for years, banks marketed purchasing cards as a stand-alone product that worked best when a company could get as many suppliers as possible to accept it." But suppliers often balked at participating, leading to only partial success. Instead, Gamble reports that the "next generation of payments automation will have “a single user interface on the front end, but four pipes on the back end” that will deliver payments by card, check, ACH or wire."
