Having a poor checkout experience can cost you customers. Research in 2025 found that nearly 40% of shoppers are no longer loyal to a single store and will readily switch to a competitor that offers a faster checkout experience. Additionally, over 61% of consumers have abandoned a physical store specifically due to long lines.
Suffice it to say, having a solid checkout system in your business can help you stay competitive. You need to invest in the right solutions to ensure that shoppers have the most convenient experience possible.
This is where wireless credit card processing comes in.
Today, wireless credit card processing, and their innovative processing machines, have given merchants more mobility than ever. Wireless payment technology allows merchants to handle credit cards, as well as cash and checks, on the floor and on the go without sacrificing security. It also leads to faster processing times and the ability to process secure transactions through wireless terminals from virtually anywhere and at any time.
But how exactly does the technology work? We’ve put together a detailed guide to wireless credit card processing and how to implement it in your business. Let’s dive in.
How wireless processing works
There are multiple wireless credit card processing types (credit cards and debit cards, contactless cards, or mobile devices) that use radio-frequency identification (RFID) or near-field communication (NFC) to accept payments. Samsung Pay, Apple Pay, Google Pay, or any bank mobile application that supports contactless payments can be used in this case.
Here’s an overview of how wireless credit card processing works:
- The merchant dips, taps, or swipes the customer’s card through a wireless credit card machine. Similar to cellular technology, the terminal connects via a secure cellular data network or WiFi to transmit encrypted transaction data to the processor, like Stax.
- The merchant services provider then passes this information to the bank that issued the customer’s credit card (issuing bank). They check to see if the card is valid. If the amount requested is available on the card, it sets aside the amount of the purchase for the merchant.
- The issuing bank sends back an approval or decline message to the merchant services provider.
- The transaction information is sent back to the mobile credit card machine. Authorization typically occurs in near real-time, often taking just seconds depending on your network connection.
- At the end of the day, the merchant manually or automatically “settles” their terminal batches and this begins the final step in the transaction process. Once the settlement process begins, the funds are transferred from the issuing bank and deposited into the merchant’s account.
With Stax, you can configure your terminal to automatically “settle” or batch out at the end of each day, ensuring your funds are deposited into your account as quickly as possible—usually within 1-2 business days.
Standalone wireless terminals vs. mobile POS apps/readers
While both payment processing solutions allow merchants to untether the checkout experience, there are some key differences between wireless terminals and mobile POS apps/readers.
Wireless processing involves a wireless credit card terminal, a keypad, and/or a display screen. Wireless terminals can often print paper receipts, and they do not require a direct hookup to a phone line or internet connection. They instead work independently and, hence, wirelessly to accept credit cards at various locations. This method of processing is widely used in service industries, such as delivery, repair, and taxi driving. Basically anywhere that employees need to process credit cards from a customer’s home or outside of a physical store (though, many restaurants use wireless terminals for servers to accept payment at the table).
Mobile apps and readers allow merchants to accept credit and debit cards through their cell phone, and they can send the customers a text or email receipt. Sometimes this involves an app from the processor (such as tap to pay through Stax) or a piece of equipment that is standalone or attaches to the phone. The technical aspects of this method are usually varied depending on your credit card processor.
A closer look at wireless credit card machines
Wireless credit card processing won’t work without the right equipment, which is why it’s worth exploring the different wireless credit card terminals in the market. These credit card machines function the same way as countertop terminals. The main difference is that they don’t have to be plugged into a power source. Most wireless payment terminals connect to your WiFi network or utilize a built-in SIM card to access 4G LTE and 5G cellular networks for nationwide coverage.
Some of the most popular wireless credit card readers and machines (and ones offered by Stax) include:
Dejavoo QD2: This mobile wireless device accepts chip, swipe, and contactless payments. It features a 5.5” color LCD touchscreen and connects via WiFi and 4G/LTE.
