您好，我參考了Wiki百科對wallet詞條的解釋。註意壹般意義上的“錢包”用wallet比較合適，purse壹般指女性專用的小錢包或手提包（相當於handbag）。
參考Wiki百科：
A wallet, or billfold, is a small, flat case that is used to carry personal items such as cash, credit cards, identification documents (driver's license, identification card, club card, etc), photographs, business cards and other paper or laminated cards. Wallets are generally made of leather or fabrics, and they are usually pocket-sized and foldable.
