How many different passwords am I supposed to remember? Every year, the number only goes up. But a tech company in Massachusetts may have solved that problem. It's developed flexible circuits that can be pressed into the skin and used to open accounts:
The tattoos have been developed by Massachusetts-based engineering firm MC10, and contain flexible electronic circuits that are attached to the wearer's skin using a rubber stamp.
Nokia has previously experimented with integrating tattoos into mobile phones, and Motorola's senior vice president of advance research, Regina Dugan, a former head of the US Pentagon's Defence Advanced Research Projects Agency, demonstrated the silicon-based technology that uses bendable electronic circuits. Initially designed for medical purposes, Motorola hopes the ‘Biostamps’ could now be used for consumer authentication purposes.
