PayPal on Thursday unveiled “PayPal Here,” a small accessory similar to the solution offered by Square, that can be used to accept credit card payments on an iPhone. The reader is a large blue triangle that connects to the top of an iPhone through the headphone jack. With the help of the “PayPal Here” iOS app, a merchant can input a sum and have a consumer swipe his or her credit or debit card to make payments. PayPal’s app also features a “Scan Card” feature, which uses the iPhone’s camera to record a credit card number or even a check. The app can track invoices and cash payments, and be used with checks, credit cards and debit cards. PayPal Here comes on the heels of the company’s unveiling of an upcoming digital wallet service that looks to compete with Google Wallet.
