Biometric Payment Arrives in a Store Near You 206

"A chain of Florida convenience stores has begun accepting fingerprints as payment, using a biometric system called Pay By Touch. The company is a Bay-area startup backed by $130 million in VC cash and the acquisition of BioPay, a Virginia-based biometrics firm that's already done $7 billion in European transactions. From the article: 'The company is a bit puzzled by customer privacy fears. After all, they say, how can using a unique fingerprint for identification be riskier to theft than a plastic card, key chain token, or account number? ...The fingerprint image recorded is not the same as those collected by the federal government or law enforcement.'"

One-way hashing would do this relatively easily. Similar to passwords if you hash the original content and then the tested content and they match there is a very high probability that it is the same original content. It is also irreversible (in bounded time).

Either way I'm not picking one up, I'll go to hand-crank radio and telegrams before I become a beacon of marketing information.
