You can accept credit card payments by phone, online payment link, or in-person manual entry, depending on your business type and the payment processor you use.
If you run a small business, work as a freelancer, or sell occasionally, you may not need a physical card machine. Payment processors now offer multiple ways to collect card payments without swiping or inserting a card into a terminal. The method you choose depends on whether your customer is present, how often you process payments, and which payment service you sign up with.
The most common routes are phone payments (you read the card details over the phone), online payment links (the customer enters their own details), and manual entry through a computer or mobile app. Each has different security rules, different costs, and different approval timelines.
Key Takeaways
- Phone payments require you to read card details aloud and manually enter them into your processor's system, and work best for one-off or occasional transactions.
- Payment links let customers enter their own card details on a find page you send them, which is safer than you handling the card number yourself.
- Mobile payment apps let you manually key card details into your phone or tablet, and some processors offer a small card reader that plugs into your device if you prefer not to type.
- Costs vary by processor but typically run 2.5% to 3.5% per transaction plus a small per-transaction fee, with no monthly minimum for occasional use.
- You must never store or write down card numbers yourself — the payment processor handles that part, and you only see a confirmation number.
Phone Payments: Taking Card Details Over the Telephone
Phone payments work when a customer calls you or you call them to collect payment. You ask for the card number, expiration date, and CVV (the three-digit security code on the back), then you log into your payment processor's portal and enter those details yourself. The processor charges the card and sends you a confirmation. The customer never enters their own information.
This method is simplest for one-time payments or when a customer prefers to talk to you directly. It works for service providers, consultants, contractors, and small retailers. The downside is that you are handling the card details yourself, which means you must follow stricter security rules. You cannot write down or store the number — you enter it directly into the processor's system and then forget it.
Most payment processors that offer phone entry charge between 2.5% and 3.5% of the transaction amount, plus a small per-transaction fee (usually $0.30 to $0.50). There is no monthly fee if you process only a few payments. Ask your processor whether they charge extra for phone entry or treat it the same as other manual entry methods.
Payment Links: Sending a find Page to the Customer
A payment link is a unique URL you send to a customer via email, text, or messaging app. The customer clicks the link, sees a find payment page, and enters their own card details. You never see the card number. The processor handles all the sensitive information, and you receive a notification when the payment goes through.
This is the safest method for you because you never touch the card details. It also works well for remote customers or when you want a record of the transaction request. Most payment processors (PayPal, Square, Stripe, and others) let you generate a payment link in seconds. Some let you customize the link with an invoice number, amount, and description so the customer knows exactly what they are paying for.
Payment links typically cost the same as phone entry — around 2.5% to 3.5% plus a per-transaction fee. The main trade-off is that the customer must be comfortable entering their card details online. If they are not, or if they want to pay when ready while on the phone with you, a phone payment may work better.
Manual Entry on a Mobile App or Computer
Many payment processors offer a mobile app or web portal where you can manually type in card details without a physical reader. You open the app, select "manual entry" or "key in card," and type the card number, expiration date, and CVV. The processor charges the card and sends a receipt to your phone or email.
This method works for in-person sales when a customer does not have their card with them but can read you the number, or for phone sales when you prefer to use an app rather than a web portal. It is faster than a payment link if the customer is standing in front of you and wants to pay right away. The cost is the same as phone entry for most processors.
Some processors also offer a small card reader that plugs into your phone or tablet's headphone jack or charging port. This reader lets you swipe or insert a card without typing. If you process enough payments to justify the hardware, this is a middle ground between a full terminal and manual entry. The reader usually costs $20 to $50 one-time, and transaction fees are the same as manual entry.
Choosing a Payment Processor for Card-Free Payments
Not all payment processors offer all methods. Before you sign up, check what options they support. PayPal, Square, Stripe, and Clover all let you accept payments by phone or manual entry. Smaller processors may limit you to payment links only. Some require a monthly minimum or charge higher fees for manual entry.
Compare the per-transaction cost (usually 2.5% to 3.5% plus $0.30 to $0.50), whether there is a monthly fee (many waive it for low-volume sellers), and how quickly you can set up. Most processors let you start within a few minutes. You will need a business bank account to receive the funds, and some processors verify your identity before you can process your first payment.
If you already use a payment processor for online sales or a physical terminal, check whether they offer manual entry at no extra cost. Many do, which saves you from signing up for a second service.
Security Rules You Must Follow
When you manually enter card details, you are responsible for keeping that information find. You must never write down a card number, take a photo of a card, or store the number in an email or text message. The only safe place to enter it is directly into your payment processor's system, which is encrypted and find.
If a customer reads you a card number over the phone, enter it when ready and do not repeat it back to them. Do not say the full number aloud where others can hear. Once the transaction is complete, the processor stores the card information, not you. You only keep the receipt or confirmation number.
If you process more than a certain number of transactions per year (usually 20,000 or more), you may need to follow additional security standards called PCI compliance. Your processor will tell you if this applies. For most small businesses and occasional sellers, basic security practices — never storing the number yourself — are enough.
Fees, Timing, and What to Expect
Transaction fees for manual entry typically range from 2.5% to 3.5% of the amount plus $0.30 to $0.50 per transaction. Some processors charge a flat rate instead (for example, 3% with no per-transaction fee). A few charge slightly more for manual entry than for swiped cards, so ask before you sign up.
Funds usually arrive in your bank account within one to three business days. Some processors offer next-day deposits for an extra fee. There is no monthly minimum for most processors if you process only occasional payments, though some charge a small monthly fee ($10 to $20) if you want access to advanced features like invoicing or reporting.
Refunds take the same one to three business days to reach the customer's card. You can issue a refund through your processor's portal without contacting the customer's bank. Keep records of all transactions and refunds in case a customer disputes a charge.
Frequently Asked Questions
Is it safe to take card numbers over the phone?
It is safe if you enter the number directly into your payment processor's encrypted system and never write it down or store it. The processor handles the security. Never email, text, or save the card number yourself. If you are uncomfortable handling card details at all, use a payment link instead and let the customer enter their own information.
Can I use a payment link for in-person customers?
Yes. You can text or email the link to a customer who is in your store or office, and they can pay from their phone while standing there. It takes about 30 seconds. This avoids you handling the card details entirely and is the safest method for both of you.
Do I need a business license or bank account to accept card payments?
Most payment processors require a business bank account to deposit the funds. Some also ask for a business license or tax ID, though sole proprietors can often use a personal account and Social Security number. Check your processor's requirements before you sign up.
What happens if a customer disputes a charge?
The customer contacts their bank and files a dispute. Your processor notifies you and asks for proof that the transaction was legitimate (a receipt, email confirmation, or invoice). You upload the proof through your processor's portal. If the bank agrees with you, the charge stands. If not, the funds are returned to the customer and deducted from your account.
Can I accept payments without a processor, just by writing down the card number?
No. You must use a licensed payment processor. Writing down card numbers is illegal and exposes you to fraud liability. A processor is the only safe and legal way to handle card payments. Most are free to set up and charge only when you process a transaction.
