Apple has just kicked off the iPad extravaganza with a big piece of news about its Apple Pay initiative. It'll launch this Monday, and now has the support of 500 US banks along with major retailers like Starbucks, Macy's, McDonald's, Disney, Walgreens and Target. To remind you, Pay will make it possible to use your iPhone 6 and 6 Plus at the till (or online) instead of pulling out a credit card, since they're the first Apple handsets with contactless NFC. It'll work in conjunction with the Touch ID fingerprint scanner, and let you use any credit cards you've stored in Passbook. Meanwhile, the new iPhones' Secure Element chip encryption is fenced off from iOS and iCloud, so that even Apple itself can't see confidential purchase information. If you're good with all that, you can give it a crack starting October 20th -- a partial list of retailers is available here.
