Remarketing to Customer's phone after PoS payment

Hello, i’m trying to find a way to connect the mobile phone of a customer, when he/she checking out to the PoS on my phisical shop. My idea is to collect phone number there, giving a 10% discount though discount code that i send to the mobile number (to check the number is correct). Than do remarketing, when customer leave. (Shopify PoS App natively permit to add email and or Phone number when you create the Account, but i would be sure they give me the correct one).
I can’t find an App that can do the job (via SMS or better Whatsapp).
Any ideas?
