Hotels are putting RFID tags in towels to catch would-be thieves.
Linen Technology Tracking, a company in Miami, has patented a washable RFID chip that can be sewn into towels, robes and bed sheets, allowing hotels to keep track of their linens.
One Honolulu hotel, which introduced the technology last summer, has reduced theft of its pool towels from 4,000 a month to just 750, saving more than $16,000 a month.
Rising cotton prices have been a motivation - A bath towel that might have cost $5 last year could cost $8 or $9 now.
Last year in Nigeria, a woman caught stealing towels from the Abuja Hilton was ordered to pay a fine or spend 3 months in jail.
