      • Amount of the transaction
      • Total Amount that needs to be finalized (including any tip)

Should I accept debit cards?

Debit cards are increasingly being used as customers’ preferred payment method. When goods or services are purchased with an ATM debit card, the funds are removed from the customer's checking account. In addition to the standard ATM cards, many banks also issue the Visa Check Card and/or Mastercard's Master Money Card – both of which can be used in either an online or offline debit arena.

What is the difference between online debit and offline debit?

The difference between these two debit choices is whether a personal identification number (PIN) is used at the point-of-sale terminal. When a PIN is used, the transaction becomes 'online' and funds are immediately withdrawn from the cardholder's available funds. When an offline debit transaction occurs, funds are not withdrawn until the transaction processes – usually two to four days after the sale.

What are commercial cards?

Commercial cards – corporate, business, purchasing – are issued to businesses as an alternative way of financing expenses such as supplies, travel, and entertainment. These cards also provide users with specific reporting advantages. By using a commercial card, cardholders get itemized records of all their purchases. This simplifies reimbursement procedures and helps track expenses. This specialized reporting is possible because specific data is captured at the point-of-sale terminal. Mastercard and Visa each provide issuers with the ability to issue commercial card products.

What is Electronic Benefits Transfer (EBT)?

EBT is the automation of cash or cash-like benefits through electronic authorization, data capture and settlement processes. This is accomplished with the use of plastic magnetic-striped cards at the point-of-sale terminal. The end result is the elimination of coupon benefits distribution. The electronic process results in increased security, thereby reducing fraud and benefit misuse.


What are Worldpay Integrated Payments’ funding timelines?

  • Standard funding timeline, including Holidays and Weekends
    • Worldpay Integrated Payments’ funding cutoff is 5 AM (EST). Batches closed before the 5 AM cutoff will fund in 2 business days.
      • If the batch from the previous business day is closed after 5 AM (EST) the following day, it will be delayed by another business day.
    • Federal Holidays will delay funding by one business day. (see below)
    • Some high-risk businesses may have different settlement options. Using Automated Clearing House (ACH), Worldpay Integrated Payments will remit funds due for Mastercard, Visa, Discover, and JCB transactions to a merchant’s business bank account.
  • Next Day Funding timelines and restrictions
    • In order to receive Next Day Funding you must be setup for the program with Worldpay Integrated Payments
    • Next Day Funding requires the merchant to close their batch by 6:50 PM (EST).
    • Please contact Worldpay Integrated Payments for more info on Next Day Funding
  • AMEX (American Express) funding
    • For AMEX Direct (ESA), AMEX handles the funding of all AMEX transactions within a batch. American Express will obtain the merchant's banking information and pay funds directly to his bank, the payment will be separate from the payment from Worldpay Integrated Payments.
    • For AMEX Opt-Blue, the AMEX transactions are deposited by Worldpay Integrated Payments. The funding will follow the same timeline as your Visa/Mastercard/Discover transactions.
    • Please contact Worldpay Integrated Payments for specifics on your business’ AMEX program.
  • Daily Discount
    • Merchants can have processing fees taken out on a per-batch basis. This results in the deposit not matching the batch amount because the fees are debited from the batch and the remaining amount is deposited.

How do Federal Reserve holidays impact funding?

  • Funding will be impacted by any Federal Reserve Bank Holidays. Your funding will be delayed by one business day.
  • For example, if the holiday is on a Monday, you will receive your funds from Thursday, Friday and Saturday on Tuesday rather than Monday.
  • Local banks may be open but no funds are moved because the Federal Reserve is closed.


What is an Authorization?

As the name implies, an authorization is a transaction you use to:

  • Help verify that the card is not counterfeit
  • Verify that the cardholder has sufficient credit for the purchase
  • Place a "hold" on the cardholder’s credit line for the amount of the transaction

An authorization is required in order to complete a Sale transaction.

What is an Authorization Completion?

The Authorization Completion is the act of closing or finalizing a transaction that has been authorized. By completing an authorization, you are ensuring that transaction will be included in your processing batch for the day.

What is a Batch? Do I need to process a deposit for every sale?

A Batch is a collection of transactions in any given time, typically for your days’ worth of transactions. A Batch Close is the action of submitting your authorized transactions for payment. While an authorization places a hold on a cardholder’s available balance to cover your payment, a batch completes the process of charging your cardholders by settling all Authorization Completions and remitting payment to your business. In most cases, Worldpay Integrated Payments handles the settlement of your batches automatically every day.

I’ve already obtained an authorization. Do I still need to process an Authorization Completion and Batch?

Yes. The funds will not be available to you unless you complete the transaction. In some cases, your system will process the completion the same time as the authorization, so no further action is needed once the authorization is obtained. Please consult your System Provider to find out more.


What is the chargeback procedure?

Most often, the first stage of a chargeback procedure comes in the form of a ‘retrieval request.’ A retrieval request is a request from a card-issuing bank to see an original, photocopy or fax of a sales draft to prove the validity of the sale. If one of your customers disputes a card brand (VISA/Mastercard) sale, you will receive a letter of notification and be requested to send a copy of the signed copy of the draft or other information to your processor. If your records are complete and you have complied with credit card regulations, as well as follow best practices set by the card brands, then you are more likely able to successfully contest chargebacks. You will receive a chargeback notification and at this time your account will be debited the chargeback amount. (the notification does not specifically say the merchant has been debited)

For complete merchant chargeback guidelines, please refer to the individual card brand websites:

Am I liable for chargebacks?

Yes, if the customer has a valid dispute with the charge in question and you do not provide the necessary documentation and/or satisfactorily remedy the situation. If, however, the customer doesn’t have a valid dispute and you complied with processing regulations, you may not be liable. If the chargeback is found to have been in error, a merchant will be granted a reversal.

What is my responsibility?

You are required to locate the signed copy of the draft or other requested information and send a copy of it to your acquirer within the time allowed. Failure to do so will result in a chargeback due to non-receipt of requested item. Your Credit Card Acquirer may request copies up to two years following the date of sale.

What are some of the different types of chargebacks?

A sale can be charged back for more than 35 valid reasons, the four most common are:

  • no signature on a draft
  • failure to fulfill a request for a sales draft
  • no imprint on a manually keyed in sales draft (for card present merchant)
  • unauthorized sale

How can I avoid chargebacks?

For card-present transactions:

  • Verify that the full card number does not print on the receipt, only the last 4 digits of the card.
  • If you manually key in a card number, get a manual imprint of the card, a signature on the imprint and verify the signature matches the signature on the card.
  • Check the expiration date and do not accept expired cards.
  • Return policies must be printed on the sales receipt close to the signature line.
  • Do not accept a card that looks to have been altered.
  • Obtain authorization for the full amount of the sale.
  • If a card is declined, do not attempt to continue to get an authorization, and ask for another form of payment.
  • Please reference the card brand’s website for additional suggestions.

For card-not-present transactions:

  • Have warranty and return/refund policies on the checkout page of your website with a click through box for the cardholder to check acceptance of the policies prior to the completion of the sale/order. If it is a written policy it must be signed and faxed or emailed back to the merchant for their records as an acceptance from the cardholder they agree to the term of the sale, return/refund policies including any warranties.
  • Use security features such as AVS to verify the billing address and zip code, and CVV2 to verify that the consumer is in possession of the card.
  • Ship goods only to the verified cardholder’s billing address and obtain a signed proof of delivery from the shipper for delivered goods.
  • Include a customer service telephone number in the billing name that appears on customer’s bank statement.
  • Never charge a cardholder’s card until the goods have been shipped.


What is the difference between Qualified, Mid-qualified, and Non-qualified transactions?

Qualified discount rate is applied for all transactions meeting the "normal" operating guidelines as outlined below:

  • All Merchants - close batches daily
  • Retail (Terminal) Merchants - magnetically swiped & electronically authorized charges
  • Internet / MOTO Merchants - electronically authorize charges using AVS and including order numbers for Visa and Mastercard transactions.

Mid-qualified discount rate is applied for all transactions meeting the operating guidelines as outlined below:

  • Retail (Terminal) Merchants
    • Manually keyed orders using AVS & order number on Visa and Mastercard transactions.
  • Internet / MOTO Merchants
    • There is no mid-qual rate for Internet / MOTO merchants.

Non-qualified discount rate is applied for all transactions meeting the operating guidelines as outlined below:

  • All Merchants
    • not closing batches daily
    • not using AVS & providing order numbers on manually keyed or Internet transactions for Visa cards.
      • High- Risk Merchants (Visa Transactions Only) following card types:
        • : Business and Corporate cards
        • : Mastercard/Visa Business cards
        • : Procurement cards (Government)
        • : Visa Signature cards
        • : Mastercard World cards


When are my processing fees taken out of my account?

  • Your statement will be uploaded at the end of the day on the 5th of every month; you may not see it until the morning of the 6th depending on your time zone. Fees are ACH’ed on the 5th of the month; it will be up to your bank when you see the fees debited.
  • The details of your fees will appear on your merchant statement that you will receive, typically in the first full business week of the month.
  • If your fees fail to be debited because of non-sufficient funds please contact Customer Care at 800-846-4472.

Why am I paying mid-qualified and non-qualified rates?

  • Visa and Mastercard have different interchange requirements based on industry type and method of transmission. Transactions that do not meet these requirements are billed at mid-qualified or non-qualified rates. Review the Visa and Mastercard Interchange Qualification Criteria for more information.

What are mid-qualified and non-qualified rates?

  • A mid-qualified rate, also known as a partially qualified rate, is the percentage rate charged to the merchant when accepting a credit card that does not qualify for the lowest, or fully qualified, rate. For example, a credit card that is keyed in versus being swiped, or one that is used as a reward or business card, does not qualify for the lowest rate. The mid-qualified rate is usually 0.50 – 1.50 percent higher than a qualified rate. It applies to retail, restaurant, and supermarket businesses. It does not apply to Internet and telephone order businesses.
  • The non-qualified rate is the highest percentage rate a merchant will be charged, usually 0.70 – 2.50 percent higher than a qualified rate. All transactions that are not qualified or mid-qualified fall into this category. Examples include: the credit card is keyed in rather than being swiped and address verification is not performed; a special kind of credit card is used like a business card and all required fields are not entered; a merchant does not settle the daily batch within the allotted time frame.

How can I get the lowest interchange rate?

  • The lowest qualified interchange rates are associated with credit or debit cards not attached to rewards programs or business accounts are present and swiped, and the merchant sales are settled daily. If anything differs from this, the card will qualify at a higher interchange rate.

Can I surcharge on transactions?

  • Surcharging credit card transactions is not supported by Worldpay Integrated Payments. A merchant may, however, offer discounts for cash transactions provided it is clearly disclosed to cardholders as a cash discount and the cash price is presented as a discount from the standard price available for all other means of payment.

What is a stored value program?

  • A stored value program allows you to offer your customers a proprietary card pre-loaded with value for future purchases. Although there are many different applications for stored value cards (Gift Card, Merchandise Return, Pre-pay), they all share some common components:
  • Magnetic Stripe Cards – The merchant gives a consumer an electronic stored value card in exchange for some kind of pre-payment. Typically, the card includes a magnetic stripe, the merchant's name or logo and an account number.
  • Transaction Processing – The merchant can process stored value transactions from the point-of-sale terminal. These transactions are delivered to Worldpay Integrated Payments' authorization system for processing in real-time and account balances are maintained for all cards.

What do I do if the Internet goes down and I cannot process?

  • Call for a voice authorization and use an imprinter any time a transaction is manually entered into your point of sale during an internet outage to minimize risk.
  • Check the draft to ensure that you have captured a clear impression of the embossed card number.
  • Complete the draft with the date, description of merchandise/service, sales tax, total dollar amount and authorization number, and get a signature.
