Paymark has seen three days in a row of transactions exceeding the five million mark (December 21-23), another first for the company.
While the final figures for today are yet to be counted it looks likely to end with more than five million transactions as well.
"The switch has held up well with no reports of problems on the network, which accounts for more than 75 per cent of the nation's EFTPOS terminals," a spokesman for Paymark said..
"The technology team at Paymark ensures the network is as resilient as possible to minimise downtime for retailers at this key time of the year.
"Even with record peaks such as the ones seen today, the network is still operating well below its maximum capacity."
