Square vs. Merchant –
I used to have a merchant account with my other business, It became costly with all the added fees, cost of the terminal, etc. I opened a Square account, and they do provide you with a customer service number if you have problems. If you use a GSM network (ATT or T-Mobile are GSM) the air-interface to the tower is encrypted. No security concerns there. Businesses all over Europe and Asia are now accepting payments through cell phones now, eliminating the need for credit cards. They have actually seen fraud go way down as a result.
THere are a few new companies coming out with similar services as Squared. I personally like the fee structure better than the merchant accounts, and the responsiveness I have seen to date. Just my two cents.
