Last week, OCR-based loyalty card scanning was added to the Android version of Google Wallet, but today the iOS faithful can get in on the action. An update allows you to add all of those pesky rewards cards that clutter the ol' billfold and ditch the unsightly key ring tags. In addition to pulling info from scanned barcodes, the new version can simply read the text on your card and fill in the appropriate fields automatically -- useful for cards that pack magnetic strips instead of barcodes. If you'll recall, credit card snapshots were enabled on the iPhone change purse last month for adding a full range of payment options. In addition to the new frequent buyer functionality, Wallet will also notify you when you're strolling past a merchant that matches one of those saved memberships. You know, just in case you're having trouble finding the nearest GameStop.
