Normally, people use both debit and credit cards separately which makes the process longer and more sophisticated. Instead of other banks having to separate Debit and Credit cards, or even combine them into the two extremities of the card. As other banks did, they can now combine two chips into one card. In response to these inconveniencies, Sacombank provides customers with a card that combines two functions into a single chip. Everyday living may be made much more "breathable" by eliminating unneeded items. ‘This’ allows us to concentrate more time, space, and energy on more important matters. By the combination of “Debit” and “Credit” characters, Mastercard Only One will give users new and unexpected experiences.
