This week's Question: Google Wallet, an Android mobile app launched earlier this month, is slowly being rolled out to the public. The application allows users to make purchases with their phones. The technology uses near field communication (NFC) chips to store and remit credit card data, discount card information, and coupons. Users must enter a four-digit security PIN on their phones before making a purchase; they then tap their phone on a store's terminal, transferring the payment from shopper to retailer. Supporters appreciate the ease of use, while skeptics still have mobile device security concerns. What do you think? Will consumers accept the growing mobile payment options?
