That is two questions, however I am going to try and reply each:
The “receiver” of a bitcoin transaction is admittedly simply an tackle that in your case occurs to be a peson and the place that tackle is related to a Pockets, e.g. a software program app, put in on a SmartPhone.
The pockets app can have an space inside it permitting customers to view transactions. Relying on the pockets, it would both show as cash despatched and obtained, or present a hyperlink to an exterior service comparable to https://blockchain.information the place information concerning the transaction could be seen. Utilizing the latter, the receiver (really, anybody) can see that the tackle you used to ship cash to, has been used as an “Output” in a transaction, and the tackle used to ship the cash (e.g. your individual pockets tackle) has been used as an “Enter” to that transaction.
In abstract: If each the sender and receiver tackle are displayed on blockchain.information, and have no less than 6 “Confirmations”, you possibly can just about safely assume that the cash have been efficiently despatched and obtained.
As for easy methods to ship cash to a different pockets, you’d comply with the identical precept:
1). Receive tackle from the individual you want to pay
2). Utilizing any pockets, punch in that tackle
3). Choose the quantity of coin to ship to that tackle
4). Hit “ship” or “pay” or no matter.
I hope that helps.
