These are SQUARE credit card readers, model A-SKU-0047 with 3.5mm posts that fit headset jacks on both iPhones and Android phones (my phone is an Android). I have been the only owner of each of them. Used on my cellphone at art shows with the SQUARE processing software to process credit card transactions. These fit in simply, easily and always work. Most transactions process at rates of 2.6 to 2.9% with $0.10 fee per transactions. Rate is 3.5% + $0.15/transactions if card number is manually entered. These are simple to use and my years of experience using them is they are flawless. Never had one not process unless the magstripe on the credit card had issues, which is not a failure of these readers but of the credit card.

The only reason I am parting with these is my cellphone just 'died' and had to be replaced. It has the "C" connector, so all these with the headset posts do not work on it.

Price for all 7 is $30.
