For screens, everything depends on your use. If you have a fixed store, prefer a tablet. You will see more information and you can use a stand, which makes it easy to take orders!

Nowadays, it is no longer necessary to choose a tablet with a 4G/5G connection. You can use your smartphone as a router and share your plan connection. Here is a tutorial to share a connection.
Note that on Tunder, it is not necessary to have a connection because the cash register is fully usable in offline mode. Very practical when you are in a place without a connection!
Storage is not an important parameter when it comes to choosing your cash register on Android. The recorded data is very light and the photos will not weigh heavily on the scale.
