bankmecu will offer its customers PayTag, a technology that allows users to make contactless payments from their mobile phones.It is the third organisation in as many weeks to announce that it will offer PayTag. Commonwealth Bank and Coles are also deploying the technology. PayTag is a sticker that users attach to their iPhone or Android phone that uses a tiny antenna to link their mobile banking application to a contactless payment terminal. Users choose the account they wish to use to make payments and the phone works in the same way as a contactless debit card.The device works on any point of sale terminal that accepts contactless cards. The same $100 maximum limit on purchases applies to both PayTag and contactless cards.bankmecu worked with banking services provider Cuscal on a PayTag trial during September.Cuscal's general manager of products and services, Adrian Lovney, said in a media release that the company will be working with another mutual to offer PayTag.
