The vertical brush tag is the latest POS terminal of Jia Lian Payment, and it is a tag model with a built-in flow card and a built-in camera. Vertical electronic signs support bank card swiping transaction, Alipay code scanning transaction, WeChat code scanning transaction and China UnionPay Express transaction.

There are several reasons for the failure of the vertical electronic signature board transaction:

1, restrictions on bank card issuers

Each bank has an independent risk control system model, and the system will make judgments based on multi-dimensional factors such as users' assets and transactions. So be sure to choose a machine that swipes the card without skipping the code. If it is restricted by the bank card issuer, you need to wait until the card is unsealed.

2. The magnetic stripe card is not certified.

The security of magnetic stripe card is relatively low, in order to ensure the card.
