With the launch of iOS6, retailers and restaurants are wondering how PassBook is different from Google Wallet. In a nutshell, Google Wallet allows you to store your credit / debit card on your Google Wallet and pay with your Google Wallet. Google Wallet is NFC based and as a result, it only works if the merchant’s POS is NFC friendly. Google Wallet does not allow the storage of egift cards, coupons, vouchers, etc. in the app.
PassBook, on the other hand, is just a place to store passes, egift cards, vouchers, etc. PassBook does not support NFC and therefore, it can only work if the merchant’s POS can scan the ecard.
So, for egift cards, ecoupons, vouchers, passes, etc. Google Wallet cannot help you so much, unless it is from a major credit card provider such as Visa and MasterCard. PassBook, on the other hand, is the perfect solution for storing your ecards, ecoupons, vouchers, etc. News is leaked that Google is going to allow storage of any ecard on the Google Wallet in the next few weeks. Until then, iPhone PassBook is a more practical solution:)
