Mobile phone credit card swiper

I am planning on getting a credit card reader for my mobile phone, so I can take credit cards.  Any suggestions "square" vs "paypal's"?

You might want to do a search on this topic as it has been discussed several times I believe.

I’ve only had the square and like it but one person made a good point - she has them all since they are free - that way if one doesn’t work or is giving her trouble, she has the others as back-up. There was one day that my square was not reading cards, so I plan to get the others at some point.

I have square, much easier to pay pal, and I've also read a lot of bad things about paypal screwing people over, namely sellers. Because their policy is to ALWAYS side with the customer.

I have both.  I find the square reader tedious to swipe cards because the way the reader is designed. They have a new card reader recently and I have not used that one yet.
I like PayPal because the reader is designed better , lower% rate  and I use PayPal to receive booking fees online. For me this makes it easier to track all my transactions. I also use paypal to buy online.
I used square for 2 years and I got the paypal reader few weeks ago.  
I have had no issues with any transactions with both of them!

Does anyone know of a similar option available in Australia?
