The balance isn't swept from the private key until you actually accept the transaction.
	*It is possible that the funds on the private key can be spent by another person between the time you scan the code and the time you commit (accept) it. The Bitcoin POS system will show a zero balance upon the initial scan if the funds have already been spent, but it is possible, for example, that another person could spend the funds ''after'' they are scanned but ''before'' the transaction is committed. In most cases, you'll be notified within a minute or two (via the Alerts screen) that a payment was rejected by the network. Also note that if a payment consisted of multiple scans, ''all'' of them must be accepted for the transaction to go through. If a single scan gets rejected due to a double-spend attempt, the entire transaction gets rejected.		*It is possible that the funds on the private key can be spent by another person between the time you scan the code and the time you commit (accept) it.

	*The Bitcoin network may charge a transaction fee under various circumstances. If you sweep ''all'' the funds from the keys present, the transaction fee will be deducted from the balance you receive. If you sweep ''some'' but not ''all'' of the funds, the fee will either be deducted from the balance you receive (default), or the change returned to the customer. This can be changed on the setup screen. Transaction fees charged by Somebody, Inc. are billed separately and are never deducted from transactions directly.		*The Bitcoin network may charge a transaction fee under various circumstances.

	The POS system acts as a client for a central server run by Somebody, Inc. It does not maintain a Bitcoin block chain, but rather, sends SSL-encrypted queries to servers belonging to Somebody, Inc. in order to retrieve rate quotes and perform transactions. Consequently, it requires a constant Internet connection in order to function. Transactions cannot take place and rates cannot be quoted without a functional connection to the Internet.
