Benefits of card machines for small businesses

Is a card machine right for your small business? Of course, it varies from business to business. But this is what it could do for you:

  1. Up your sales –
    Today’s customers expect to pay by card, and giving them what they want will help stop them from walking
  2. Build your credibility –
    Card machines make you seem more professional, which is especially important if your small business is still fairly newborn
  3. Save on admin –
    Forget the bank runs and streamline your account management by linking your terminal to your computer or smartphone
  4. Take safer payments –
    Card machines have extra security built-in to protect both you and your customers
  5. Be ready for the future –
    Cash is drying up, and it’s a good idea to think ahead – so fill in our handy quote finder without delay, and get the cardreader ball rolling for your business.

Tips for choosing the best card reader for your small business:

To help you pick the ideal provider for your business, here are the five key considerations:

  1. Sales –
    Some providers have flat rates whereas others will offer cheaper fees the higher your sales volumes. Check that your sales volume will match the provider’s minimum requirements to make the most of any deals to be had.
  2. Mobility –
    A mobile card reader that you can take to your customers is especially helpful if you’re in the hospitality industry.
  3. Number of devices –
    Customers don’t like waiting to pay, and poor service might stop them coming back – make sure you have enough machines to allow maximum payment efficiency.
  4. Which types of card do I need to accept? –
    Most people understand that small businesses may only be able to accept a limited number of cards, but the more options you give your customers to pay with, the better.
  5. Accepting contactless –
    One in three UK card payments are made using a contactless card or e-wallet. Therefore, having a contactless point of sale option is a must, especially if you’re often making sales of £30 or less.
