With growing interest from both advertisers and retailers in the interactivity that can be achieved from installing DTAG100 dynamic NFC tags alongside digital screens, Dot Origin has invested significantly in advancing the potential of this solution through its new 2waytap technology. The latest version of the DTAG100, now available to selected partners, enables near-instantaneous two-way exchange of data between mobile phones and advertising screens, kiosks and point-of-sale systems. As well as enabling the launch of mobile apps with unique or personalised data, using 2waytap allows such systems to obtain crucial user identity or transaction information from each mobile in return, subject to the usual app privacy controls, resulting in a truly personalised and interactive engagement at each tap.
