Visa says it will introduce “tokenization” by mid-April. The technique substitutes your credit card information with a series of numbers that can be used to authorize payment without revealing your actual account details. When you use your smartphone to make a contactless payment, the token is submitted, instead of your account information.
The introduction of token-based security by Visa and rivals including MasterCard and American Express was a key component in the launch of Apple Pay in the US last year.
That's good news for iPhone 6 customers, but it's also good timing for the launch of Apple Watch.
