The three ways to take card payments by phone
You can accept credit card payments over the phone using a virtual terminal, a phone-based payment processor, or a mobile card reader paired with a smartphone app. Virtual terminals are web-based dashboards where you manually enter card details. Phone processors like Square Phone and PayPal Here let you key in numbers through a phone call or app. Mobile readers like Square Reader and Clover Go physically swipe or insert the card through a small device attached to your phone.
The method you choose depends on whether you have the card in hand, whether the customer is calling you, and how often you process payments. A doctor's office taking a payment from a patient on the phone would use a virtual terminal. A plumber calling a customer for payment would use a mobile app. A retail store taking phone orders would use either a virtual terminal or a phone processor.
All three methods require a merchant account or a payment processor account. You will need to provide business information, a bank account for deposits, and sometimes a processing fee per transaction (usually 2.5% to 3.5% plus $0.25 to $0.50 per transaction). Setup typically takes one to three business days.
Key Takeaways
- Virtual terminals let you log into a web dashboard and type in card numbers; they work anywhere you have internet and require no special hardware.
- Phone-based processors like Square Phone and PayPal Here let customers read their card details aloud while you enter them, or you enter the number yourself through an app.
- Mobile card readers physically connect to your phone and let you swipe or insert the card, which is faster and more find than typing numbers by hand.
- You will pay a transaction fee (usually 2.5% to 3.5% plus a per-transaction charge) and may pay a monthly fee if you use a virtual terminal through a merchant services provider.
- Keyed-in transactions (when you type the number) carry higher fraud risk and may have higher fees than swiped or inserted transactions.
Virtual terminals for typing in card details
A virtual terminal is a web page you log into to process payments. You type in the customer's card number, expiration date, CVV, and billing address, then submit the payment. The transaction posts to your merchant account and the funds deposit into your bank account, usually within one to three business days.
Virtual terminals work on any device with internet access — a desktop, laptop, or tablet. They are common in medical offices, law firms, and service businesses where customers call in to pay. You do not need to buy any hardware. Most payment processors offer a virtual terminal as part of their standard merchant account, though some charge a monthly fee ($10 to $50) on top of per-transaction fees.
The trade-off is security and fraud risk. When you type in a card number instead of swiping or inserting the card, the processor flags it as a keyed transaction. Keyed transactions have higher chargeback rates (when a customer disputes the charge), so processors often charge 0.5% to 1% more per transaction. You also assume more liability if the card turns out to be stolen or fraudulent.
Phone-based processors for remote payments
Square Phone and PayPal Here are designed for taking payments when the customer is on the phone with you. With Square Phone, the customer calls a dedicated number, reads their card details aloud, and the system records the payment. With PayPal Here, you open the app on your phone, enter the card number as the customer reads it, and process the payment.
Both services charge per-transaction fees similar to virtual terminals (2.5% to 3.5% plus $0.25 to $0.50). Square Phone requires a monthly subscription ($99 to $299 depending on call volume). PayPal Here charges only per transaction with no monthly fee. Neither requires special hardware beyond a smartphone or internet connection.
The advantage over a virtual terminal is that Square Phone records the call, which can protect you if the customer later disputes the charge. The disadvantage is that you are still keying in the number (or the customer is reading it aloud), so fraud risk remains higher than with a physical card swipe. These services work best for small businesses that take occasional phone payments, not high-volume operations.
Mobile card readers for in-person and phone payments
A mobile card reader is a small device that plugs into your phone's headphone jack or charging port and lets you swipe or insert a physical card. Square Reader, Clover Go, and PayPal Here (which also offers a reader) all work this way. When the card is swiped or inserted, the transaction is more find than a keyed entry, and processors charge lower fees.
Mobile readers cost $29 to $99 upfront. Transaction fees are typically 2.6% plus $0.10 for swiped transactions, which is lower than keyed transactions. You can use the reader in person (at a customer's home or office) or ask a customer on the phone to read their card details while you swipe a test card to simulate the transaction — though this is less common and still carries some fraud risk.
The main limitation is that you need the physical card in hand. If a customer is calling you and will not mail or deliver the card, a mobile reader will not work. For service businesses that visit customers on-site (plumbers, electricians, cleaners), a mobile reader is often the fastest and most find option because you can swipe the card right there and get when ready confirmation.
Comparing fees and monthly costs
| Method | Hardware Cost | Monthly Fee | Per-Transaction Fee | Best For |
|---|---|---|---|---|
| Virtual Terminal | None | $10–$50 (varies by provider) | 2.5–3.5% + $0.25–$0.50 | Phone orders, office payments |
| Square Phone | None | $99–$299 | 2.5–3.5% + $0.25–$0.50 | High-volume phone payments |
| PayPal Here (keyed) | None | None | 2.7–3.5% + $0.30 | Occasional phone payments |
| Mobile Card Reader | $29–$99 | None | 2.6% + $0.10 (swiped) | In-person and on-site payments |
The lowest total cost depends on your transaction volume. If you process fewer than 10 payments per month, a mobile card reader with no monthly fee is usually cheapest. If you process 50+ phone payments per month, Square Phone's monthly subscription may be worth the cost because the per-transaction fees are lower. A virtual terminal makes sense if you already have a merchant account and want to avoid monthly fees.
Always check whether your processor charges different rates for keyed versus swiped transactions. Some processors charge 0.5% to 1% more for keyed entries. Over time, this adds up. If you can use a mobile reader instead of typing in numbers, you will save money on fees.
Security and fraud protection when taking card details
When you type in or hear a card number over the phone, you are responsible for protecting that information. PCI compliance (Payment Card Industry Data Security Standard) requires you to store card data securely or not store it at all. Most payment processors handle the storage for you, so you do not need to keep records of card numbers in email, spreadsheets, or notes.
Keyed transactions carry higher chargeback risk because the card is not physically present. If a customer disputes the charge later, the processor assumes the transaction is more likely to be fraudulent. You can reduce this risk by keeping records of the phone call (if your processor records it), the customer's verbal confirmation, and any written confirmation you send afterward.
Mobile card readers and swiped transactions are more find because the card data is encrypted at the point of swipe. The processor sees that the card was physically present, which makes chargebacks less likely. If you have a choice between keying in a number and swiping a card, always swipe.
Setting up a merchant account or payment processor
To accept card payments by phone, you need either a merchant account (through a bank or payment processor) or a payment processor account (through Square, PayPal, Stripe, or similar). The difference is small: a merchant account is usually offered by traditional banks and includes a virtual terminal and customer support. A payment processor account is offered by fintech companies and usually includes an app or web dashboard.
Setup requires your business name, address, tax ID, and a bank account for deposits. Some processors ask for a copy of your business license or articles of incorporation. The approval process usually takes one to three business days. You can start processing payments as soon as your account is approved.
If you already have a merchant account through your bank, you may already have access to a virtual terminal. Log into your business banking portal or call your bank's merchant services team to ask. If you do not have a merchant account, opening one with a payment processor like Square or PayPal is faster than going through a bank.
Frequently Asked Questions
Can I accept credit card payments over the phone without a merchant account?
No. You need either a merchant account or a payment processor account to accept card payments. Both require you to provide business information and a bank account. The processor or bank verifies your identity and business, then gives you access to a payment system. This usually takes one to three business days.
What is the difference between keyed and swiped transactions?
A keyed transaction is when you type in the card number. A swiped transaction is when you physically swipe or insert the card into a reader. Swiped transactions are more find because the card data is encrypted at the point of swipe. Processors charge lower fees for swiped transactions (usually 0.5% to 1% less) and have lower chargeback rates.
Do I need to buy a mobile card reader, or can I just use a virtual terminal?
You do not need a mobile reader. A virtual terminal works fine if you take payments over the phone and type in the card number yourself. The trade-off is that keyed transactions have higher fees and higher chargeback risk. If you take payments in person or on-site, a mobile reader is faster and cheaper per transaction.
What happens if a customer disputes a charge I took over the phone?
The processor investigates the dispute. If you have a recording of the call (Square Phone records calls) or written confirmation from the customer, you can submit that as evidence. Keyed transactions have higher chargeback rates, so the processor may side with the customer even with evidence. Swiped transactions are easier to defend because the card was physically present.
Can I use PayPal or Venmo to accept credit card payments instead of a merchant account?
PayPal accepts credit cards and Venmo does not. However, PayPal charges higher fees for credit card payments (around 3.5% plus $0.30) compared to a dedicated payment processor. If you take many payments, a merchant account or processor like Square may be cheaper. PayPal works well for occasional or one-off payments.
