T+1' s settlement method is in line with UnionPay's fund settlement method, and T+1' s POS machine is very safe and stable. The normal capital settlement mode of T+1 is that after the customer swipes the card, the acquiring institution of the POS machine will transmit the transaction to the clearing institution, and the clearing institution will then transmit the information to the cardholder's card issuer.

after the customer consumes, the clearing institution will transfer the funds to the account designated by the acquiring institution on the next working day. Because the T1 payment can't be cleared until the clearing institution goes to work, the payment company has introduced the T payment mode.

T collection can be received on the same day, which greatly facilitates the capital turnover of users. However, the handling fee for T collection is higher than that for T1 collection. If users spend more than one time, it is best to use T1 consumption.
