At a 7-Eleven convenience store in Taiwan, you can pick up a 4-inch plushie of Miffy, the bunny character from the Netherlands, a mini bento box charm complete with a realistic chicken drumstick, or a tiny plastic rotary phone. Produced by iCash Corporation (a 7-Eleven affiliate), these keychains are more than just trinkets: Each contains a contactless chip that connects it to Taiwan's elaborate stored-value payment system.
You'll now be able to do contactless credit and debit card payments on all Bay Area transit agencies. Also, if you use your Clipper Card, you can get discounted and free transfers between agencies. Riders will only be charged full fare for the first agency they use and if they transfer to a different agency, they will get a discount up to $2.85. If the fare of your next ride is below that, your ride would be free.
