Which portable credit card reader works best with Android for events?

[Bea55]

Need a credit card reader that's portable and works with shopify and android. The one recommended by shopify for androids is on backorder. I have my first event in 2 weeks and need to get one. Any suggestions?

I don't think there are any solutions.

You will either need to use a third party credit card processor, get an iPad and compatible reader, buy a POS Go device, or input the credit card # manually.
