Using iPad 2 as a POS Terminal

[asiadelights]

Hi, Im looking to get a couple of ipads as a pos terminal, and I found that the minimum requirement is ios 9, which is available on the iPad 2. Being an older device, anyone here has any experience working with them? Will it be slow or trouble setting it up?

Thanks!

I have been using an ipad 2 with 9.3.6 for development and testing.  It isn't as fast as other devices i've used (iphone Xr, Samsung A 8"), but it isn't painfully slow either.  Switching between food and beverage categories half second, items with variable rates seem to about 3/4 of a second to bring up the pricing input.  I am in Colombia, everything moves slower here.
