servers.

Digital wallets are being used more frequently among Asian countries as well. One in every five consumers in Asia are now using a digital wallet, representing a twofold increase from two years ago. A
MasterCard mobile shopping survey among 8500 adults, aged 18–64 across 14 markets, showed that 45% of users in China, 36.7% of users in India and 23.3% of users in Singapore are the biggest adopters of digital wallets. The survey was conducted between October and December 2015. Further analysis showed that 48.5% of consumers in these regions made purchases using smartphones. Indian consumers are leading the way with 76.4% using a smartphone to make a purchase, which is a drastic increase of 29.3% from the previous year. This has inspired companies like Reliance and Amazon India to come out with their own digital wallet.

Security
Consumers are not required to fill out order forms on each site when they purchase an item because the information has already been stored and is automatically updated and entered into the order fields across merchant sites when using a digital wallet. Consumers also benefit when using digital wallets because their information is encrypted or protected by a private software code; merchants benefit by receiving a combination of protection against fraud, faster receipt of payment, decreased transaction costs, and decreased theft loss.
Digital wallets are available to consumers free of charge, and they're fairly easy to obtain. For example, when a consumer makes a purchase at a merchant site that's set up to handle server-side digital wallets, they type their name, payment and shipping information into the merchant's own form. At the end of the purchase, the consumer is asked to sign up for a wallet of their choice by entering a user name and password for future purchases. Users can also acquire wallets at a wallet vendor's site.
Most, if not all digital wallets offer advanced security features e.g.
biometric authentication
