Samsung has a payment platform for their Android phones that is supposed to rival ApplePay. It looks like Samsung needs to do more work because their service definitely is not bulletproof.
Samsung Pay works by issuing a "token" that the merchant receives instead of your credit card number. This process is supposed to protect your credit card number and keep it private. It turns out, the more tokens Samsung issues, the more predictable they become. Hackers can steal the tokens and use them on their own phones. Nice!
