PAX Terminals: The S58 and Other PAX Models
PAX terminals, from older countertop models like the PAX S58 POS to current Android devices, are sold through many processors. PAX makes the hardware. The company that sold you the terminal sets it up and sets your pricing. Here is how to tell which model you have, when an older one needs a look, and what to check on your statement.

Short answer
What should I check if my business uses a PAX terminal?
PAX terminals range from older countertop models like the S58 to current Android devices. Older models may lose software or security support, so ask your provider whether yours is still supported. Check whether the terminal is owned, leased or bundled into your rate. Send your statement for a free statement review.
What PAX terminals are
PAX Technology makes card terminals: countertop machines, PIN pads and handheld Android devices. Processors and independent providers load their own payment app and sell them under their account terms.
The S58 is an older PAX countertop model. Current PAX lines include the A80 countertop terminal, the A920 handheld family and the A35 PIN pad. Your provider can confirm which models it still supports.
Who PAX terminals fit
- Counter checkouts at convenience, liquor and grocery stores
- Merchants with an older PAX S58 POS who want to know if it is still supported
- Businesses that want a simple card machine rather than a full POS
- Owners checking whether a terminal lease still makes sense
PAX S58 POS and current PAX models
- PAX S58
- An older PAX countertop terminal. If yours still runs, ask your provider whether it still gets software and security updates.

- A current Android countertop terminal with a touchscreen, keypad and built-in printer. See our PAX A80 terminal guide.
- PAX A920 family
- Handheld Android terminals with a built-in printer, used for payments at the table, the curb or on the go.

PAX terminals at a restaurant or bar
Restaurants and bars often use a PAX handheld for payments at the table or along the bar, with a countertop model at the host stand. Tip prompts and tip adjustments depend on the payment app your provider loads.
If your terminal is older, ask whether it supports tap to pay and current card security standards before a busy season, not after it stops working.
What to check on your statement if you use a PAX terminal
- Which PAX model you have, and whether your provider still supports it
- Whether the terminal is owned, leased or bundled into your rate
- Monthly terminal or software fees per device
- Whether the terminal is locked to your current processor
- Any fee to replace or repair an older device
PAX terminals questions
Still not sure? Ask us directly.
Is the PAX S58 POS still supported?
It depends on your provider and the payment app on the terminal. The S58 is an older model, so ask your provider whether it still gets software and security updates and whether it takes tap to pay. If not, plan a replacement before it fails.
Where can I get a PAX S58 POS board?
Ask your provider or PAX to identify the right part and a repair option. A board repair on an older terminal can cost more than a supported replacement, so compare both before you pay for parts.
Is PAX a payment processor?
No. PAX makes terminals. Your processor or provider loads the payment app and sets your pricing, which is why two merchants with the same PAX model can pay different amounts.
Can you review my statement if I use a PAX terminal?
Yes. Send one recent monthly statement, every page. We separate processing fees from terminal and software fees and tell you whether your device is owned or leased.
