What does Walmart have that bitcoin doesn't have? The custodial coin, no need to call blockchain for each transaction. Ledger fees drop to almost trivial for most items.
- Walmart beat on both the top and bottom lines, boosted by strong online sales.
- Same-store sales rose for a 13th consecutive quarter.
- The retailer raised its fiscal year 2018 adjusted earnings per share guidance.
- Walmart shares are trading at an all-time high.
What about those fingerprint cards? Not fully autonomous cash cards, but the next step up in debit cards. Walmart needs to offer a branded version of that and allow short term credit to their customers.
Then Walmart collects all the transaction fees, even as it offers even money on interest charges. Their store policing costs go down, but their bad debt recovery process ramps up. From that point is is simple for Walmart to offer fully intelligent cash cards, with the help of hardware wallet vendors.
