A guide to setting up card payments for your business

Fewer and fewer people carry cash. If your business only takes bills, you're losing sales you never even see: the person who doesn't have cash and walks somewhere else. The good news is that taking cards today doesn't require an expensive terminal or a contract with the bank. With a small reader or even just your phone, you can start charging in minutes. This guide walks through the options without the jargon.

Understand the three ways to take cards

Before choosing, it helps to know what's out there. The most common options for a small business are three:

• Mobile reader: a little device you connect to your phone or tablet by cable or Bluetooth that reads the customer's card. It's usually cheap or even free to start.
• Tap to pay from your phone: your own phone becomes the terminal. The customer taps their card or phone and you're done, no extra hardware.
• Point-of-sale terminal: a fuller piece of equipment, screen and all, for businesses with a counter and high volume. It's the priciest option and the one you'll need later, if at all.

For most people starting out, a mobile reader or tap to pay from the phone covers everything you need.

The best-known platforms

Three names dominate this world and are worth knowing. Square offers a free reader when you sign up and is famous for how easy it is to get going; its app turns your phone into a terminal. Stripe is very powerful, especially if you also sell online, and has its own small reader that connects over Bluetooth. And Clip, very popular in Mexico and Latin America, offers affordable readers built for the local business. All three share one idea: it costs little or nothing to start, and you only pay a fee when you actually charge something.

The beauty of these tools is that you don't pay to have them. You pay only when you sell, which is exactly when you should pay.

How to get started, step by step

The real process is simpler than you'd imagine. In broad strokes, it looks like this:

• Create an account with the platform you choose and download its app on your phone.
• Request or buy the reader, or activate tap to pay from the phone if your device supports it.
• Connect the reader (by cable or Bluetooth) and give the app the permissions it asks for.
• Run a test with your own card for a tiny amount to confirm everything works.
• Set up where you want the money to land: your bank account, usually within one or two business days.

Watch the fee, not just the price of the device

The reader may be free, but every charge pays a fee: a small percentage of the sale. That fee is what really matters in the long run, because you pay it on every transaction. Compare each platform's rates by how you charge —card present, remote, online— and pick the one that best fits your kind of sale. And check how long deposits take: one day versus three can matter for your cash flow.

Taking cards and booking can go hand in hand

Accepting cards doesn't just close more sales: it also lets you take deposits to secure appointments, which is key if you suffer from people who book and don't show. Many businesses combine WhatsApp booking with a charge or deposit at the time of reservation; an agent like Lidia can confirm the appointment and, depending on how you set it up, point the customer toward payment. Fewer holes in the calendar and less money left on the table.

Takeaway

Taking cards is no longer just for the big players. Pick a platform like Square, Stripe, or Clip, start with a mobile reader or tap to pay from your phone, run a test, and pay close attention to the fee and deposit times. It's one of the fastest changes you can make to stop losing the customer who only brought plastic.
