PAX A920 Terminal: Unboxing, Features, and Our Review

The PAX A920 terminal has made significant inroads into the British market, thanks to increased recommendations from various payment providers. With its ergonomic design and cutting-edge technology, this smart POS terminal competes robustly with popular models from Ingenico and Verifone. Mobile Transaction has tested the device to assess how well it meets your expectations. 

What is the PAX A920? 

The PAX A920 terminal is manufactured by PAX Technology, a renowned Chinese company specialising in payment devices. With offices in Woking and Horsham, the company has a significant presence in the UK. The A920 is a “smart POS” terminal due to its touchscreen interface and versatile software, making it a portable, self-sufficient checkout solution. It caters to entrepreneurs, sole traders, and small businesses looking for a blend of design and practicality. 

Key features include: 

  • Modern and sleek design 
  • Customisable to business needs 
  • Acceptance of various payment methods 
  • Portability 

One of the standout features is its Android operating system, which allows you to install and use PAX-based applications relevant to your business, similar to customising a smartphone or tablet through apps. This transforms the terminal from a simple card payment device to a smart device with expandable functions such as reporting and customer loyalty features.

The PAX A920 terminal and its charging base are packaged separately. 

POS Terminal Packaging: The packaging is standard and protective, though not particularly impressive. Inside, you’ll find the USB cable, printer roll, and adapter in a separate compartment. The display is protected by a transparent film, which should be removed before use. 

Charging Base: The charging base is purchased separately, although some suppliers may offer it in a package deal. Note that the cable for the charging base is included with the terminal package. 

Features in Detail 

The PAX A920 terminal is aesthetically pleasing with a pearl white plastic surface and sleek lines. The 5” touchscreen covers most of the front side, enhancing ease of use for any application. The smooth surface is also easy to disinfect, which is crucial for hygiene, especially in retail environments. 

The terminal accepts various payment methods, including chip and PIN, contactless, magnetic stripe, NFC, and QR code payments. It also features an integrated printer for paper receipts and offers WiFi and 4G connectivity, with a built-in SIM card connecting to mobile networks. 

Security and Additional Features: The terminal complies with EMV and PCI 5x standards, ensuring transaction security. It can also run multimedia files included in apps, explaining the presence of volume adjustment buttons. The rear camera can scan barcodes and QR codes, which is useful for applications requiring touch-free payments. 

Receipt Rolls: The terminal uses standard 57 mm wide and 40 mm diameter receipt paper rolls. Changing the roll is straightforward and quick. 

Battery and Charging: The battery is removable but currently cannot be easily replaced by the user. For replacements, contact your POS supplier. 

Charging Base 

The charging base, while not essential, is practical for those who need to keep the terminal on a counter surface. Though the base is made of slightly cheaper-looking plastic, it effectively supports the terminal on a flat surface. 

Where to Get the PAX A920 

Several UK payment providers offer the PAX A920, including Takepayments, Elavon, and Valitor. Typically, you’ll need to sign a contract for at least a year, covering card acceptance, terminal rental, and servicing. 

Our Opinion 

The PAX A920 is a strong competitor to Ingenico’s popular Move 5000 terminal. Its minimalist design, large user-friendly display, and Android OS make it an excellent choice for small businesses needing mobility, such as restaurants, events, fairs, and taxis. Despite its sleek design and functionality, businesses need to weigh the benefits of a touchscreen terminal against the traditional push-button models they might be accustomed to. Overall, the PAX A920 stands out for its versatility, ease of use, and robust feature set.
