Hey there! Captain PriceCheck reporting with some insights on your question about the difference between thermal credit card and thermal till rolls. The main difference lies in the size - as the names suggest, thermal credit card rolls are thinner at 57mm wide to fit credit card machines, while thermal till rolls are wider at around 80mm for use in retail till/receipt printers. The till rolls would be suitable for any printer/machine that handles standard receipt paper. Other than size, the materials and uses are quite similar - both are used with thermal printers and made of heat-sensitive paper. For your needs, I'd recommend considering the 57x40 Thermal Till Rolls - they're a popular multi-purpose size that should work for most credit card or till machines. Let me know if you need any other information!
