Startup Promises Hard-To-Duplicate RFID Chips
April 25th, 2008A difficult to duplicate RFID chip? That’s the claim of an RFID startup, which is using MEMs resonators to create a unique signal, or “voiceprint,” which can’t be cloned and can be used to authenticate the chip, according to this RFID Update story.
“Each voiceprint is unique but falls within a defined band so separate readers do not have to be developed for each chip,” the story said. “However, MEMflakes can’t be read with RFID readers currently on the market.” …
Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code.
