How does a PDQ machine work?

How does a PDQ machine work- ComparedBusiness

The main function of a PDQ machine is to accept payments. You have the following choices for handling payments with PDQ machines:

  • Contactless (Using digital wallets, debit cards, or credit cards)
  • Chip & PIN

Steps to process transactions

Keep in mind the following steps so you can process payments by using the Chip and PIN or contactless method easily.

  1. Start by putting the total charge for the customer’s purchase into the machine and double-check the amount
  2. Ask the customer if they will be paying through a card or digital account. Request your customer to slide their card against the PDQ machine if they are paying through a credit or debit card. However, if your customer wants to pay with their digital account, ask them to tap their mobile instead.
  3. If the customer is paying via the contactless method, you don’t likely need a password to process the transaction. If it’s a card payment, the machine will ask for a PIN. Instruct your customer to enter their 4-digit PIN.
  4. The machine will then process the transaction. It checks the PIN with the customer’s bank and confirms there is enough money for the transaction. This step is automatic and may take a few moments.
  5. If a transaction goes through, the payment will be sent within 24 hours from your merchant account to the business’s bank account.

Taking payments via contactless method with a PDQ machine

To accept contactless payments through debit or credit cards, or with digital wallets, the process is:

  1. Your customer taps their card or mobile device against your compatible PDQ machine.
  2. The approval request is sent to the customer’s card provider, which checks the customer has the funds to clear the transaction.
  3. If the customer has the funds, the transaction is approved and the money is transferred into your merchant account.
  4. If the customer doesn’t have the funds, the transaction will be declined.
  5. For approved transactions, the funds will be transferred from your merchant account into your business’ bank account – this can be as quickly as 24 hours.

Types of PDQ machines

PDQ machines are of various types, you can select the one most suitable for your business.

  • Countertop 
  • Mobile
  • Portable

We’ve discussed the features of each type of PDQ machine, the businesses for which they work best, and their advantages and disadvantages.

Countertop PDQ machines

How does a PDQ machine work (2)- ComparedBusiness

The most commonly used type of PDQ is a countertop machine, which is directly attached to a POS. A POS (point of sale) is a place where customers pay for products or services.  It can be a computer or a cash register. 

Countertop PDQ machines are connected with POS, so payments can be processed at the same place where they were made.

Ideal for:  Brick-and-mortar stores like supermarkets, retail stores, hair salons, etc. that have a fixed till point.

Benefits Drawbacks
  • User-friendly as it's the most common type of PDQ machine.
  • They are physically connected to the point of sale, which makes the connection stable.

  • You cannot move the PDQ machine around, hence zero mobility.
  •  It takes up a lot of space in a business setting.

Portable PDQ machines

Portable PDQ machines are also called wireless chip and PIN machines. Portable PDQ machines are handheld devices that can process transactions via Wi-Fi or Bluetooth to send data to the POS. Portable PDQ machines have a maximum range of up to 100 meters.

Ideal for: restaurants, cafes, coffee shops, bars, clubs, fine dining, or any businesses that want to offer the best service and ease for their customers.

Benefits Drawbacks
  • Better experience for customers as they don’t need to wait in line for their payments to be processed.
  • Increased mobility as compared to countertop PDQ machines.
  • Sleek designs that are handy and take up less space.
  • The device needs to be charged.
  • Wifi range of 100 meters from the POS. 
  • working of the machine depends on Wifi/ Bluetooth.
  • Disruption in connection results in failed transactions.

Mobile PDQ machines

Mobile PDQ machines use wireless technology, such as Wi-Fi or mobile data networks, to connect to POS.  Unlike traditional PDQ machines that are fixed to a location, mobile PDQ machines can process payments anywhere. They are also not limited to a specific range. They will work efficiently even outside the business premises, as long as you have an internet connection.

Ideal for: businesses that travel a lot, like food truck businesses, delivery services, market stalls, or taxi drivers.

Benefits Drawbacks
  • Compact designs that take up less space, are perfect for businesses that are on the go.
  • Not limited to business premises.
  • Not reliable if you have a poor internet connection.
  • The device needs to be charged.
  • Usually, more than one device is needed to carry out transactions.

Costs Related to PDQ Machines

How does a PDQ machine work (5)- ComparedBusiness

When you’re thinking about getting a PDQ machine, it’s important to know about the related costs so you can make the right choice for your business. 

Here’s a simple breakdown of what to expect:

Setup costs

The first cost to consider is the setup fee. This is a one-time fee that’s usually between £100 and £150. 

Buying vs. Renting a PDQ Machine

You’ll also need to decide whether to buy or rent the PDQ machine. 

  • Renting can cost you around £15 a month. This is a good option if you want to keep things affordable upfront. But renting has its downsides—many providers obligate you into contracts, and upgrading your system later might be difficult.
  • If you buy the machine outright, you avoid the monthly payments and have more freedom to grow and upgrade your system in the future. The purchase price can range anywhere from £19 to £230, depending on the type of machine you choose.

Monthly Fees

There are usually two main monthly costs to think about: merchant account fees and service charges.

  • A merchant account is needed for processing transactions, and these fees typically start at £10 per month.
  • Minimum Monthly Service Charge (MMSC) is usually around £15 a month. It’s a fixed expense that the providers charge to make sure they cover their costs, even if your business processes fewer card payments.

If your business doesn’t process many card payments, look for a provider without a minimum usage fee.

Transaction Fees

A transaction fee is applied every time your PDQ machine processes a card payment. This can either be: 

  • A percentage of the transaction- between 1% and 3%.
  • A flat fee per transaction- around 10p to 30p.

£100 - £150
