SAN FRANCISCO (Reuters) - Shares of radio-frequency identification (RFID) chipmaker Impinj Inc pared gains on Monday after Inc said its new checkout-free grocery store, which opened to the public on Monday, does not use the technology.

Investors have speculated that Impinj could sell components to Amazon. Its shares surged as much as 18 percent earlier in the session. They were up 8.5 percent at $25.19 in early afternoon trading.
