The campaign will announce a convention-wide rollout of Square, a device on the cutting edge of mobile donations, reports James Hohmann of POLITICO. Square-enabled phones and devices will be used throughout the 2012 Republican national convention providing a quick and easy way for delegates and visitors to make donations and buy souvenirs with a simple swipe of their credit card onto a mobile device. ‘We are excited to be the first Presidential campaign to make serious use of Square devices at a major event like a national convention.’ Zac Moffatt, Digital Director of the Romney campaign, says in a forthcoming statement. This lets grassroots supporters accept credit and debit card donations, which should help Mitt with small-dollar donors. Square devices will also be provided to each Victory location.
