It retrieves user’s payment information automatically and transmits it via NFC to the payment terminal during payment.

If data is stored, the user need not connect to the internet. NFC uses EMVCo or tokenization technologies while developing a mobile wallet for iOS. To develop an Android mobile wallet app, NFC and HCE technology are the best options.

Bluetooth and iBeacon-

iBeacon technology is an excellent way to transfer data, and it does not require internet. Smartphone with Bluetooth can communicate with an external BLE transmitter, i.e. beacon. POS terminal fetches the necessary details stored in the mobile wallet of the user through beacon devices and Bluetooth technology. It makes shopping simpler for shoppers.

Why mobile wallet security matters?

To understand how to develop a mobile wallet app, let us read further.

#1. Allow users to create own profile:

The developer should offer each user an option of creating a unique profile. The user can store all the details such as name, mobile numbers, address, bank details, transaction details, etc. in the profile. This feature plays a vital role as it offers personalized service and ease in accessing the app.

#2. Let them sync more than one bank details:

There is a possibility that user might have more than one bank account. The app must have the option of syncing bank details of more than one bank. Developers need a tie-up with all the banks to proceed with this functionality. Initially, developers can collaborate with big and famous banks only.

#3. No minimum transaction rule: 

An excellent mobile wallet app allows users to transfer even 1 dollar. It depends on the app development services management to decide what should be the maximum limit of the transaction. There is also a maximum transaction limit.

Imagine your user is buying some fruits and is not carrying cash. The vendor has an option of mobile wallet payment. The bill is 2 dollars. The user should be able to pay a small amount like 2 dollars to the vendor. This feature is the most liked feature by users.

#4. Split bills option:

mobile wallet app split bill

Some advanced mobile wallet apps are offering a feature of split bills. The user needs to add profiles of other users and add total bill amount. the app then splits the amount. App also notifies the other group members. This feature is best suitable for college going crowd and students who usually follow same bill split formula.

#5. Let them use without adding bank details:

Many mobile wallet apps have not made it compulsory to sync bank details with the app. What if anyone wants to use the app but does not have a bank account. In such cases, the user can use the app but cannot transfer money to the bank. Only if another user sends money to this user, then the only user can use that much of amount for transactions.

#6. Let them send money to those who are not using the app:

What if you want to send money to your father through the mobile wallet and your father is not using a mobile wallet. Don’t worry. Do you have his bank account details like name of the person, account number, bank name, branch name, IFSC code, etc.? User needs to put these details in the app. All e payment apps have an option called transfer money to the bank account.

#7. Receipts:

Every user must get an acknowledgment in the form of digital receipt. When you visit a restaurant, after paying the bill, the manager gives you a receipt. When you buy something from a shop, the shop employees give you a receipt of payment. These receipts are proof of transactions.

No matter transaction was successful or not; the user must get an acknowledgment about it. In the mobile wallet app, the user gets a digital receipt of every single transaction. The receipt has details such as amount transacted, date of the transaction, time of the transaction, sender details, receiver details, etc.

#8. Reward points:

Have you ever got any notification from mobile wallet apps about rewards or discounts? The apps offer a certain percentage of discount to the users after a payment transaction.

Like this, top app developers can offer such rewards, discounts, etc. many apps offer free vouchers if the user transfers a particular amount or more.


Gone are the days when people used to pay bills by visiting the bill payment centers. That process was too hectic and required much time. Ever since the USA has become digital, people have started paying bills online. The mobile wallet market is seeing a great hike.

Hence, developers must consider this market and start developing a mobile wallet app. Developers must take care of security issues, offer various features like reward points, split the bill, syncing more than one bank details, etc.
