A new research survey shows that Apple Pay is gaining momentum at the expense of rivals like PayPal.

Apple Pay is proving popular among customers using mobile payment services. New data from 451 Research shows that people making purchases with a service like Apple Pay, PayPal, or Google Wallet prefer Apple Pay over other services. Apple's service outperforms others, with 66% of customers saying they were very satisfied with Apple Pay, over 45% for PayPal and 33% for Google Wallet.

Among those planning to make purchases with a mobile payment service in the next 90 days, 45% of customers chose Apple Pay, up 5% over the last few months. Over the same period, PayPal has seen a 5% decline in the number of users expressing a desire to use that service.

More users are feeling confident about the security of mobile payments. This latest survey reports that 24% of customers feel that mobile payments are more secure than traditional credit cards, up from 14% of customers one year ago, and despite some trying to link services like Apple Pay with credit card fraud.
