Just noticed this... last couple of years, all the Galaxies have included an IR emitter. When used in conjunction w/ S-Pay, it blasted barcodes (like grocery store club cards), which made it MUCH more reliable than relying only on the barcode on screen. I only noticed it missing on my S10+ tonight when the self checkout scanner wouldn't read my club card. Bummer. I guess it would have required an even bigger punch through the screen to include it in the S10.
