What Features Do I Need to Look For in the Best Mobile Credit Card Processing Solution?

Your credit card processing solution is a very important aspect of running your business, just as important as the bank you work with. Apart from the fees charged or types of cards the processing service is compatible with, a few factors serve as popular characteristics of the top mobile credit card processing solutions in the market.

1. Fraud Protection and Security

Security, especially when it comes to financial activities, is the most important aspect of running a business on the internet. The existence of hackers on the internet is not a new concept. To protect yourself and your customers from credit card fraud, you need to choose a processor that provides sufficient security solutions for your transactions.

Spotting secure solutions have been made a fairly easy task thanks to the existence of different regulatory bodies. Certificates of PCI compliance and EMV compliance are great indications of reliable credit card processing services.

Some other security options that assure you of secure transactions include security code input requirements or the collection of a customer’s zip code before the transaction is completed.

The continual adoption of evolving security technologies is also an indication of consistent security. These technologies, as we have today, include biometrics, tokenization, and end-to-end encryptions.

A mobile credit card processing solution that offers insurance to cover worst-case scenarios also helps you avoid irretrievable financial losses for both you and your customers.

2. Great Customer Support

This is one feature that could only be truly measured through the reviews of other business owners making use of the payment processing solution. However, good customer support, which is responsive, readily available, and offered through real human communication, could also be indicated by the existence of advanced customer support options.

Alongside offering support through chat, email, and international call centers for troubleshooting issues, the top mobile credit card processing solutions additionally offer enhanced assistance. These enhanced support options include onboarding and activation, and regular interviews of business owners to help with any difficulties not reported.

3. Additional Services

Payments through credit cards are not the only way transactions are facilitated over the internet. Therefore, choosing a service that comes with other payment processing solutions for debit cards and invoices helps you create a more seamless financial workflow. Credit card processors should accept mobile credit card payments.

Some other additional services that also prove to be beneficial include credit lines and loans, payroll management, inventory organization, employee management, external platform integrations, and customer engagement options.

Regardless of all these features, the best mobile credit card processing solution is one that caters to your peculiar business needs.

Choosing a mobile credit card processing solution is dependent on the type and size of your business, your cash flow, level of reinvestment, payroll, expenses, and other transactional outflows involved in running your business. Therefore, features to look out for in a mobile credit card processing solution need to sufficiently cover these peculiarities.

Mobile Credit Card Processing Fees and Rates

Mobile credit card processing services generally operate a fee structure that is cheaper and smaller than that of their full-service counterparts.

Unlike full-service processing solutions, the top mobile credit card processing services even waive regular fees such as set up fees, monthly fees, monthly payment gateway-related fees, early termination fees, or PCI compliance or noncompliance fees.

Monthly fees tend to be discomforting for a lot of businesses, especially small-scale businesses that only process a small number of transactions per month. So, rather than adopting these fees, top mobile credit card processing services implement a flat-rate structure. With a flat-rate structure, you pay a fixed rate per transaction.

A flat rate typically takes two forms: a percentage of the whole transaction volume and, in some cases, a percentage that is additionally charged alongside a little service fee. Flat-rate pricing that includes an additional service fee typically consists of a transaction volume percentage lower than when only a percentage is charged.

For example, rather than paying a monthly $15 fee, a US-based mobile credit card processing solution charges you 1.8% of the transaction volume on average. Services that additionally charge a $0.5 fee per transaction, for instance, could charge 0.5% of the transaction volume.

Nonetheless, one fee that proves to be unavoidable is the chargeback fee, which is charged when a customer disputes a payment and the transaction is then reversed. This is more common with online sales.

While most of the top services charge the same rate regardless of the type of transaction, some charge a slightly higher rate for American Express and international cards. Payment services also charge different rates for debit and credit card processing while using a full-service payment processor results in you having to pay set up and monthly fee, among others.

Mobile Credit Card Readers

Mobile credit card processing solutions require minimal pieces of equipment to work. All they basically need is a phone or tablet with an internet connection, a credit card payment app installed on this device, and a mobile card reader to interact with the card.

Mobile credit card payments are never feasible without a card reader so, because of this, a lot of processing services provide you with one for free. Sadly, card readers that come for free are typically devoid of any form of EMV compliance.

EMV cards are smart cards that come protected with a pin or signature as well as other advanced security technologies. Free card readers typically do not possess this security technology, may not be compatible with Europay, Mastercard, or Visa cards, and, consequently, limit your payment options.

You could also accrue chargeback fees from your payment processing service. So, upgrading or purchasing a card reader that accepts EMV chip cards allows you to extensively prevent card fraud and keep your financial environment from having any loopholes.

Some of the best mobile EMV card readers are also equipped with NFC capabilities. There is compatibility with a wide variety of payment methods, meaning you get to receive payments through swiping of magstripe cards, dipping of EMV chip cards accompanied by a pin, and tapping contactless cards for swift payments.

Mobile wallets like Apple Pay or Google Pay also allow you to make payments by tapping your phones on a card reader. A top card reader possesses compatibility with this intuitive option.

Top mobile card readers are also characterized by in-built receipt printing and barcode scanning capabilities. Card readers also form a part of a fully equipped payment terminal consisting of a cash drawer, separate barcode scanner, separate receipt printer, mobile applications, a virtual terminal, business management, and employee management tools.

What is the Best Mobile Credit Card Processor?

The best mobile credit processor for you depends on the needs of your business. With so many mobile credit card payments solutions in the market claiming to be the best for you, it is important to take a deeper look into these processors beyond their bold statements on their websites.

If you are looking for a secure mobile credit card processing solution that offers you multiple fee waivers with a variety of business tools, Square is the go-to option.

For businesses that engage in cross-border e-commerce transactions and need a suitable credit card processing app to handle their needs conveniently, PayPal Credit Card Processing is a great option. Shopify Payments is the best mobile credit card processing solution for Shopify stores.

If you are in search of a mobile credit card payments solution that offers high security through multiple compliance certifications, SumUp is the go-to pick.
