轻松跟踪应用程序中的物理项目
我目前正在开发一个跟踪实际库存的应用程序。我想知道是否有某种方法可以使用 QR 码或某种条形码来扫描物品，然后让应用程序识别该物品并快速有效地提取该物品的信息。如果有人有更好或更多的想法来解决这个问题，请务必参与，我正在努力为用户提供更好/更简单的用户界面。
I am currently in development of an app that keeps track of physical inventory. I am wondering if there is some way that I could possibly use QR Codes or some kind of barcode to scan an item and then have the app recognize the item and pull up the info for the item quickly and efficiently. If anyone has a better or more ideas to solve this then please by all means pitch in I am trying to make a better/easier UI for the user.

您在这里有一些选择：
iPhone 3GS/4、iPod touch -> Infinite Peripherals 的 Linea 条码扫描仪（他们有自己的 SDK）也有磁卡读卡器。 Apple 在他们的商店中使用这些 iPod touch 的外部配件，如果您碰巧去 Apple Store，您可以看到他们的员工携带这些配件。非常可靠的选择。价格约为 300 ~ 500 美元一件。（Nordstorm、Sears、Kmart 也有使用）。
Verifone 销售类似的配件，但它们不像 Infinite Peripheral 条码扫描仪那么受欢迎。
或者使用相机读取 QR/条形码非常简单且快速。您可以使用 ZXing、Zbar sdk 扫描条形码，并且在成功扫描的基础上，如果您有可用的网络服务，您可以查找库存。这些是免费的 SDK。 Zbar 真的很快，我推荐使用 Zbar。您有一些使用摄像头的付费条形码扫描仪，例如 RedLaser。
要管理库存，请准备好网络服务，您需要提取商品的描述、价格等信息并在表格视图单元格中显示。更好的 UI 取决于您的要求以及您想要显示的数据类型。您想对库存做什么。在我得出结论之前，有很多问题，这个用户界面看起来更好。
您可以查看shopsavvy api，它根据条形码从数据库中提取商品信息。不过有偿服务。
You have some options here:
iPhone 3GS/4, iPod touch -> Linea Barcode Scanner(they have their own SDK) by Infinite Peripherals that has magnetic card reader as well. Apple uses these external Accessory for iPod touches in their stores, if you happen to go to Apple Store you can see these their associates carry them. Very reliable option. Costs about $300 ~ 500 a piece.(Nordstorm, Sears, Kmart use them as well).
Verifone sells similar accessory but they aren't as popular as Infinite Peripheral barcode scanners.
Or Reading QR/Barcode using camera is really simple and fast. You can either use ZXing,Zbar sdk to scan barcode and based upon successful scan you can lookup inventory if you have a webservice available. These are free SDK's. Zbar is really fast, I would recommend using Zbar. You have some paid barcode scanners using camera as well like RedLaser.
To manage inventory have your webservices ready, you need to pull information like description, price about item and display in tableview cell. Better UI depends on your requirements and what kind of data you want to show. What you want to do with inventory. So many questions before I can jump to conclusion that this UI looks better.
You can look at shopsavvy api that pulls up item information based on barcode from their database. Paid service though.
