The generation of each device is the biggest single factor in a quote, and in whether it can be reactivated at all. Here is how to tell the common Toast devices apart.
Handhelds
The Toast Go 1 is retired and cannot be reactivated. The Toast Go 2 has a built-in reader for dip, swipe and tap, and its chargers do not fit the Go 3, which uses a magnetic charging cable and its own dock (source).
Terminals
Toast Flex 3 is the current countertop terminal; Toast calls the Flex 14" the previous generation (source). Elo V2, V3 and V4 terminals are supported; the Elo V1 is retired (source).
Card readers
In the Toast app, current readers show as TOC300 (on-counter) or TDA300 (direct-attach); legacy Toast Tap readers show as BBPOS Chipper 2X (source).
Toast's own identification guide covers every device (Toast: what kind of hardware do I have). Or photograph the label on each device and attach it to your quote request.
Questions and answers
Which Toast devices can no longer be reactivated?
Toast lists the Toast Go 1, Elo V1, older Samsung, Acer, Azpen and OnePlus tablets, POSPAD, Teamsable, MR18 and Open Mesh access points, the MagTek eDynamo, and any device on Android 7.x or 8.0 as no longer supported. Toast says these need a new device to be purchased.
