paybytouch.gifTwo months ago, we wrote about how fingerprint payment, long talked about, had finally arrived.

San Francisco start-up, Pay By Touch Solutions, announced $130 million in financing as it planned to roll out a way for you to use your fingerprint to pay for groceries and other goods and services.

It has since shown it is pretty serious about its pledge to be in some San Francisco areas retailers by first quarter of next year. Lately, it has gone on a pretty impressive acquisition binge. Take a look at these announcements; they are being made every couple of days. It is buying up companies that will help it market other goods to you, based on your preferences — all linked to your fingerprint. So, for example, when you’re in a restaurant, it will potentially know you like green tea, and offer you a premium Chinese brand at a discount, etc.

Yesterday, it announced it had acquired two more companies, including 7th Street Software, of Berkeley, which is backed by Alafi Capital.
