Excilan has introduced a way to pay for public wireless Internet access using a mobile phone without a password.
The system makes it possible to pay and log on by simply answering the phone and pressing a button, Excilan chief executive officer Lodewijk Cornelis claimed.
He expected wireless internet service providers, Wisps to use the system alongside other payment methods such as a monthly subscription, credit card billing or the sale of prepaid scratch cards.
Travellers passing through Amsterdam's Schiphol airport, for example, can log on to the Attingo wireless network using Excilan's payment system, or by buying an access code from a vending machine in the airport at a cost of €9 (£6) per day.
Excilan runs a payment clearing system, so prices are fixed by individual operators. The company will charge an annual subscription fee and a per-transaction fee to Wisps and mobile phone network operators using the service.
Apart from Attingo, five other Wisps use or plan to use Excilan's payment system: IFatport, Megabeam Networks, Netario.com, TLC France and WLAN.
Mobile networks in Iceland, France, the Netherlands and Switzerland have so far signed up to the service.
