KaLeFu is a convenient mobile payment product launched by China UnionPay. It is a portable POS machine. "KaLeFu" is a mobile payment hardware product that connects a mobile phone or mobile smart terminal with a bank card. Use hardware encryption to protect mobile payments. Supports credit card repayment, bank card balance inquiry, transfer and remittance, mobile phone recharge, game card recharge, Q coin recharge, attraction tickets, communication bills, hotel specials tonight, cashier, air ticket booking, mobile mall shopping, national traffic fines, water, electricity and gas Fee payment and other services.

Judging from its product introduction, Kalefu is a mobile card swipe device based on the UnionPay payment channel. It is similar to Lakala and only has the function of reading magnetic strips. The focus is on the matching mobile phone. In terms of application (in fact, it is the same if you enter the card number manually, and you don’t need that hardware at all), it is a personal application, not a POS machine. It does not have the security of mobile POS, and the mobile phone cannot encrypt the data string, and it cannot print. If something goes wrong with the purchase order, the bank cannot adjust the order. You and the cardholder can only bear the responsibility. Because the success of all card transactions is based on the purchase order, it is recommended that you do not use your mobile phone to swipe the card. As a tool for collecting accounts, if something happens, it will be too late to cry.

As for the account issue, you can bind public and private accounts at will, all in the mobile application.
