im钱包 is a popular mobile payment service in China developed by Tencent, the same company that created WeChat. It allows users to connect their bank cards and make payments through their mobile phones.

The English name for im钱包 is "WeChat Pay". It is called WeChat Pay because it is integrated into WeChat and users can make payments using the WeChat app. WeChat Pay has become one of the most popular mobile payment services in China, with over 800 million users.

To use WeChat Pay, users need to link their bank cards to their WeChat account. Users can then use the WeChat app to make payments by scanning a QR code or by sending money directly to another WeChat user. WeChat Pay also offers a range of additional features, such as allowing users to transfer money to friends or pay bills.

WeChat Pay has a variety of security measures in place to protect users' financial information. For example, when making a payment, users need to enter a password or use fingerprint recognition to confirm the transaction. Additionally, WeChat Pay encrypts all financial information and does not store users' bank card numbers on their servers.

Yes, foreigners can use WeChat Pay. However, they first need to link a Chinese bank card to their WeChat account in order to use the service. This can be done by opening a Chinese bank account or by using a third-party service that allows foreigners to link their international bank cards to WeChat Pay.

Currently, WeChat Pay is only available to users with a Chinese bank account. However, Tencent is working to expand the service internationally and has already launched the service in a number of other countries, including the United States and Europe.
