US-based Early Warning Services, the company behind Zelle, said that US-based financial services firm Citi (NYSE: C) will offer Paze, the bank-offered online checkout solution, expanding access to millions of customers through one of the largest US credit card issuers, the company said.

Seventy-two percent of US consumers surveyed value the efficiency of digital wallets for online transactions and 82% trust their banks' safety and security more than third-party payment options.

With Paze digital wallet, customers can check out online seamlessly without manually entering card details. Paze also offers added security through tokenization so that actual card numbers are not shared with merchants.

Eligible Citi cardmembers will be able to activate Paze through Citi.com, the Citi Mobile App or mywallet.paze.com. Customers can then look for the Paze button at the online checkout of participating retailers and easily complete their purchase with just a few clicks.

Paze is available at leading online merchants in apparel, electronics, jewelry, food, entertainment, beauty and more.

Citi joins a group of banks and credit unions providing online checkout through Paze. Paze will be available to eligible Citi cardmembers in the coming weeks.
