Terminals

A terminal is a physical yetipay device used to accept in-person card payments. Every terminal is linked to a site within your merchant account.

When a customer taps, inserts, or swipes their card at a terminal, the resulting transaction is attributed to the site that terminal belongs to — and settled alongside all the other payments from that site.

How terminals fit in

Merchant
 └── Site (in-person)
      └── Terminal 1
      └── Terminal 2
      └── Terminal 3

Each terminal in your estate is registered to exactly one site. You can have as many terminals as you need on a single site.

Key things to know

• Terminals belong to in-person sites. A terminal can only be linked to a site that's configured for in-person payments.
• Transactions follow the site. The terminal itself doesn't affect settlement — what matters is which site it's linked to. All terminals on the same site settle together.
• Managed through Basecamp. You register, configure, and manage your terminals through Basecamp.
• Virtual devices for testing. You don't need physical hardware to start building. Use virtual devices in the test environment to simulate terminal interactions.

Serial numbers

Each Yeti terminal has a unique serial number (sometimes referred to as a Device ID). This is permanent — it will never change — and is how you identify a specific device across Basecamp and the APIs.

Format

The serial number always consists of two parts: the model code followed by the device ID, separated by a dash. Both parts are required — the serial number isn't valid without them.

Value	Valid?	Why
123456789	No	Missing model code
000123456789	No	Missing model code
S1F2000123456789	No	Missing dash separator
S1F2-000158243352274	Yes	Model code + dash + device ID

Finding it on the device

1. Tap the settings icon on your Yeti.
2. Tap Device Info.
3. You'll see the model code and serial number listed separately — combine them with a dash to get the full serial number.

In this example the model code is S1F2 and the serial number is 00158224211093, so the full device serial is S1F2-00158224211093.

Integration options

Depending on your setup, there are different ways to interact with terminals:

Integration	How it works
Pay At Counter	Your POS system sends a payment request to a terminal via the cloud API
Pay At Table	The terminal initiates the payment (e.g. tableside in a restaurant), syncing back to your POS
On Device (Android Intents)	Your Android app runs directly on the yetipay device and triggers payments locally
