You need to accept more than cash if you sell pretty much nowadays and want to make it as easy for people to pay. Credit card swipes, EMV chips, and contactless payment methods are all a must. What you may not know is that all of those different payment methods do not require a large, overpriced POS System. All you need is a contactless payment called Square Contactless and Chip Reader, which is discounted on Amazon right now.
