If you walk into an environment where debit and credit card payments are accepted, it straight away builds a trust element. It is also a good way to entice potential custom from individuals who only have a set amount of cash on them. Seeing the sign “card payments accepted here” can also encourage spontaneous purchases. It is always important to secure logos of the cards you do accept i.e. Visa, MasterCard, Amex and so forth, this again builds trust and assurance and can transform the way people shop with you.
