Over the past few years, various companies have been coming up with the mobile wallet feature. This is a service which allows the user to use their phone while making any kind of purchase instead of carrying their card. There are NFC based devices which are used so that the customers can go ahead and use the service.

For iPhone users, we have the Apple Pay which is reining the throne right now, however it does have its own competitors for Android users there are services like Samsung pay, Android Pay and Google Wallet that are the major players while there are also some that are small competitors.

For security reasons, the card details of the user are not stored however there is an Account Number that is unique for every device. Every time the user uses this service a code is generated which can be used only once for a single transaction. This is part of the security measure to ensure that there are no unnecessary charges; this means that every transaction has its own code that helps complete the transaction.

In order to maximize the convenience, for iphone users, they have the benefit to go ahead and use their iPhones by holding it out with their Touch ID button using their finger or thumb. For those who have Apple Watch, all they need to do is just raise their hands and let their wrist face the reader.

While one could think that things can get as easy as this it seems like Google has proved everybody wrong. The Google hand free version allows a person to make payments without doing much. All they need to do is inform the cashier that they wish to make the payment using Google and walk away smiling with whatever they have brought.
