Using RFID to coordinate sales floor promotional displays with ad campaigns has yielded a 54 percent increase in sales at Germany’s $68 billion Metro Group. The sales increase figure was one of several pro-RFID numbers mentioned in an October 27 speech by Metro’s IT office chief, Gerd Wolfram, according to RFID Journal.

Wolfram reportedly said Metro, the world’s fifth largest retailer, found that using RFID-tagged pallets for inventory tracking brought a “significant reduction of shipping mistakes and resulting compensation claims,” in addition to a 15 percent cut in truck unload time and halving the time it takes to verify proper item delivery. Metro, using products from Checkpoint, is about to experiment with using item-level RFID tags as the sole method of theft deterrence in stores.

The trick is to have authentication performed on a separate, much more strongly secured host - such as an Active Directory Domain Controller, or a Kerberos server, or a NIS+ server, or even using something as banal as an LDAP-over-SSL authentication dialog. In these environments, the odds of the "password file" being stolen and subjected to an offline attack go to near zero, and only online attacks may be carried out by the attacker. With sensible exponential backoff between failed password attempts, lockout after a modest number of failed attempts on a single account, and pattern detection, that minimum 7 character password is quite secure enough. Passwords aren't dead yet for security purposes, and they will be with us for a very long while to come for practical purposes. The trick is to employ them correctly. Read more...
The possibilities you describe are years away from being implemented at best, so for the moment passwords are an ugly reality. Luckily, password managers can easily manage hundreds of passwords of any length. The only thing a user needs to remember is the master password. It seems like an easier task to educate users on how to use password managers rather than implement complex security technology on a global basis. Read more...
