How does the speed of transactions differ between EDC machines and POS systems?
The speed of transactions differs between EDC machines and POS systems based on their design, processing capabilities, and the additional tasks they handle during each payment. An EDC machine is built primarily for one purpose: to process card transactions quickly and efficiently. Because it focuses only on reading the card, sending the transaction request, and receiving approval, the entire process is usually very fast.
This makes EDC machines ideal for environments where quick checkout is important, such as small stores, service counters, and mobile businesses. They have minimal software layers, fewer background processes, and straightforward functionality, allowing payments to be completed within a few seconds. POS systems, while also designed to handle payments smoothly, often take slightly longer depending on how many tasks are running at the same time. A POS device typically manages billing, item-wise details, inventory updates, tax calculations, customer data, and receipts alongside processing the payment. Because of these added operations, the system may require a few extra seconds during busy periods or when handling complex bills. However, modern POS systems are equipped with powerful processors and optimized software that still ensure payments are completed efficiently. In many businesses, the slight difference in speed is balanced by the added convenience of having all operations handled in one device. POS machines also support multiple payment modes such as UPI, cards, wallets, and QR payments, making the checkout flow smoother even if the process is not as rapid as a basic EDC device. Providers like NTT Data Payment Service design both EDC and POS machines to ensure reliable and fast processing, but the actual speed depends on the type of transaction and the features in use. For pure card-swiping speed, EDC machines are quicker, but for complete billing and operational flow, POS systems provide a more comprehensive and efficient experience overall.
