Modern electronic payment terminals(EPTs) owe their flexibility and mobility to advanced technologies, and among these, the SIM card plays a central role. But why is it so essential to the smooth operation of an EFTPOS terminal?
What is a SIM card in an EFTPOS terminal?
The SIM card built into a payment terminal works like the one we use in our smartphones. It connects the POS terminal to mobile networks (3G, 4G or 5G), ensuring data transmission to bank servers. This mobile connection is crucial to guarantee smooth, fast and secure payments, even in areas without Wi-Fi or Ethernet cabling.
Key benefits of SIM cards for VSEs
1. Total mobility for professionals
Itinerant retailers, whether food trucks, local markets or temporary events, benefit from a payment solution that works everywhere. For example, at a particularly busy festival, Easytransac solutions equipped with SIM cards enabled several stands to offer fast card payment, avoiding long queues.
2. Transaction security
Mobile networks, especially those operated via professional SIM cards, offer greater security than public Wi-Fi connections. With Easytransac, every transaction is encrypted, reducing the risk of fraud and ensuring customer confidence.
3. Service continuity
Connection interruptions can be costly for retailers. Multi-operator SIM cards (Orange, Free, SFR, Bouygues), often included in the Sumni or Pax Eftpos terminals offered by Easytransac, automatically switch between different networks to maintain a stable connection.

Is it possible to do without a SIM card?
For merchants operating in locations with a stable Wi-Fi connection, the use of a SIM card is not mandatory. Payment terminals can be configured to operate solely via a Wi-Fi connection, offering an equally effective solution. However, in the event of a local network outage, a SIM-equipped terminal remains a more reliable alternative for ensuring transaction continuity.
eSIM: a growing trend for very small businesses
Although eSIM is still under development for payment terminals, it represents a promising development. This technology could enable even more flexible management and shorter installation times by eliminating the need for physical SIM cards. Manufacturers could consider this innovation for future generations of terminals.
Conclusion
The SIM card is much more than just a module for payment terminals: it's an indispensable solution for ensuring mobility, security and reliability in environments with no fixed connection. However, for stationary businesses with a reliable Wi-Fi connection, it's not always necessary. Pax and Sunmi terminals, available from Easytransac, offer this essential flexibility to meet the varied needs of professionals.
